How to handle very large data with Tableau

All,

I am using Tableau 9.0 to do data analysis. My data set is very large containing 100 billion records.

I want to use filter to filter out the data firstly. But, when I try to add filter on the specific column of the data in Tableau, it keep running… for ever. The reason is tableau wants to display all this field value to me with ascending order, then allow me to make selection. e.g to select only one or two value to filter…

But it keeps running due to 100 billion records. How to solve this problem? Could I switch off this function (display all specific field value..)? How to filter so large data sets?

Thank you in advance

Tableau 201: 5 Tips for Creating Efficient Workbooks

One of the most common questions we receive from new Tableau users is, “How much data can Tableau handle?” Further, we commonly undertake Tableau engagements with the exclusive goal of making workbooks run more efficiently.

Tableau is capable of handling extremely large data sets, and the software only becomes more powerful with each new release.

That being said, providing an answer on how much data Tableau can handle is a tricky question, and that’s because “big data” is a relative term. Whenever a new field is placed on a view, Tableau queries the underlying data to visualize the answer.

This works much like when a database query language like SQL is used to ask questions of a database. For this reason, the efficiency can depend on many factors including not only the number of records, but the processing power of the hardware, the complexity of calculations, the type of data, etc.

This post shares five tips we use to make your Tableau workbooks run more efficiently.

Credit: It’s hard to pick just five Tableau efficiency tips, but the following was prioritized in part because of this great Tableau post: 6 Tips to Make Your Dashboards More Performant by Nicholas Hara.

5 Tips for Creating Efficient Workbooks in Tableau

1. Think Strategically About the Data You Absolutely Need

By far the most powerful efficiency gains that we have witnessed was when the size of the data set was reduced by removing irrelevant data from the file. This may seem obvious, but we can’t tell you how many times we have seen authors attempting to visualize more data than they need.

For example, if the company-wide standard for your analyses is year over year, don’t even bring in the data from three years ago. In this scenario, you immediately remove at least one-third of the data before you’ve even started!

Another piece of low-hanging fruit we often see is the aggregation of dates.

For example, your company may be collecting data at the timestamp level, but if your analyses do not require hour / minute / second level views, you can aggregate the dates by day. This will significantly reduce the number of records.

These are just two common examples, but bringing in only the data you need is the first step to creating efficient workbooks in Tableau.

Prepare Data Before It Gets to Tableau

In the Shape Data step of the INSIGHT Framework for Data Visualization series, we mention that we prefer to prepare our data before it gets to Tableau.

While Tableau has many powerful data preparation features, they are not the primary value of the software, and there are better tools for this specific job.

We recommend using a tool outside of Tableau to prepare the data set, so that once you start using it in Tableau, Tableau can do what it’s best at.

Use Context Filters

We have combined the “first” tip into parts because preparing and limiting the size of the data are that critical to the efficiency of your Tableau workbooks.

Another way to limit the data that Tableau is visualizing is to leverage “context filters”. Context filters are processed before anything else and can be thought of as temporary tables for your view.

When a context filter is used, Tableau creates a subset of the data set limited to the filter selection; then all subsequent filters hit only the subset of the data. Any dimension filter can be used as a context filter by right-clicking on the filter from the Filters Shelf and choosing “Add to context”.

2. Limit Filters; Use Apply Button

When you think about filters as queries on the data, it makes logical sense that each incremental filter on a view will add processing time. While we don’t have a hard and fast rule for how many filters are acceptable, prioritizing which fields should be available as a filter can dramatically improve the efficiency of your views.

If fields should be filtered more permanently, consider the first tip above and either filter the data before it gets to Tableau or add the filter to context to speed up processing.

One way to reduce filters on a dashboard is to use dashboard actions instead.

Using a sheet as a filter or adding a filter dashboard action that runs on hover or select provides a more efficient means for filtering the rest of the dashboard.

If you are using filters, a handy feature of Tableau is that dimension filters that are being shown to end users on the view can be set to process only after all changes to the filter have been selected

For example, if you are showing a dimension filter that includes 10 dimension members, then by default, Tableau will apply the filter every time a dimension member is checked or unchecked on the filter. So if you uncheck one dimension member, the view is reprocessed; uncheck a second dimension member and the view is reprocessed again.

If you would prefer that the view only process after both dimension members have been unchecked in this scenario, click the dropdown arrow on the filter, hover over “Customize”, and select “Show Apply button”.

Now the filters will be processed only after the end user has made their filter selections and then clicked the “Apply” button.

3. Reduce the Number of Marks

When you think of each data point, or mark, as a record that needs to be processed on a view, this tip also makes logical sense: the more marks that need to be processed, the longer it may take for the visualization to appear.

The efficiency tips to this point should have a big impact on the number of marks you are left to work with, but this is still good to keep in mind. Depending on your analysis requirements, it may not always be possible to reduce the number of marks on a view, but sometimes there is an opportunity to change the level of detail to improve efficiency.

Consider ways you can aggregate data points into hierarchies and / or make the analysis less granular.

4. Boolean > Integer > Float > Date > Date Time > String

One of the most valuable features of Tableau is its ability to execute custom calculations on the fly.

This allows for ‘discovery’ analytics, where you can quickly pivot through different analyses without even necessarily knowing exactly what you are looking for. While the calculations are very powerful, they can come with a cost to the efficiency of the workbook.

To help get the most out of the calculated fields functionality and keep your workbooks running smoothly, think about the data types in your calculations.

Not all data types are created equal in terms of efficiency, with data types going in this order from most efficient to least efficient:

Boolean > Integer > Float > Date > Date Time > String

Here is a short definition for each.

Boolean – A true or false binary result

Integer – Whole numbers

Float – Any number including decimals

Date – Date aggregated at the day level

Date Time – Date including the timestamp level

String – Text

5. Reduce Sheets, Dashboards, Data Sources

This tip not only helps with efficiency, it will help you keep your sanity and improve the end user experience.

In general, the more sheets, dashboards, and data sources you have in a workbook, the more potential there is for the workbook to run slowly. This is especially true when you are combining many different sheets on a dashboard with views that are blending data from multiple data sources.

As with database architecture, your Tableau workbooks will run more efficiently if you put some thought into how workbooks can be broken down into smaller, individual files.

Not only will this help with efficiency, it will be easier for you to manage and help your end users. This is even easier and more efficient if you have Tableau Server or Tableau Online because several smaller workbooks can share the same data source saved to the cloud.

In the case that we truly have several dashboards that are connected, we like to create a navigation dashboard that helps the end user locate the most relevant views for their specific business questions.

If you have Tableau Server or Tableau Online, the navigation links can be set up to open new dashboards by simply adding URL dashboard actions with links to the dashboard locations online.

This same technique can be used from within specific dashboards (i.e. add a URL action to run on Menu that links the end user to another dashboard / additional information).

While this isn’t a comprehensive list of Tableau efficiency tips, we have found that implementing these tactics follows (at least) the 80 / 20 rule, in that these five tips alone should help capture at least 80 percent of the possible efficiency gains in your workbooks.

Tableau Online Site Capacity

Your Tableau Online site comes with capacity to support all your users’ analytic needs. A site’s capacity includes capacity for storage and tasks that need to be performed on the site for extracts, metrics, subscriptions, and flows.

Summary

The following table summarizes the capacity allowances for your site by feature. You can find more capacity information by the features listed below.

Capacity Type Capacity Allowance Storage Site 100 GB 1 TB with an Advanced Management license. For more information, see Advanced Management capacity. Individual workbook, published data source, or flow size 15 GB 25 GB with an Advanced Management license. See Advanced Management capacity. Extract refreshes Daily refreshes Up to 8 backgrounder hours per Creator license Concurrent refreshes Up to 10 jobs Up to 25 jobs with an Advanced Management license. See Advanced Management capacity. Individual refresh runtime 2 hours Metrics Daily refreshes Up to 8 backgrounder hours per Creator license Concurrent refreshes Up to 10 jobs Individual runtime 2 hours Subscriptions Concurrent subscriptions Up to 10 jobs Individual subscription runtime 2 hours Individual email size 2 MB Flows Concurrent flows 1 per Resource Block Individual flow runtime See Job runtime capacity. Flow memory usage size 7.5 GB Visualizations Load time Up to 5 minutes Query usage size 20 GB

Storage capacity

A Tableau Online site comes with site and individual content storage capacities.

Site storage: A site comes with 100 GB of storage capacity. Workbooks, published data sources, and flows count toward this storage capacity.

Individual workbook, published data source, and flow size: An individual workbook, data source (live or extract), or flow published to your site can have a maximum size of 15 GB. Note: If your extract data source exceeds 10 GB in size, we recommend that you consider either using live connection to the database or aggregate the data in the extract to reduce its size. Frequently republishing or refreshing large extracts can be time intensive and usually indicates that more efficient data freshness strategies should be considered.

Visualization capacity

Each site comes with designated capacity to load and query individual visualizations, also known as views. You can find more information about each capacity type below.

Load time: A site has capacity to spend up to 5 minutes to load a view.

Query usage size: A site has capacity to use no more than 20 GB of memory to query a view that uses an extract data source. The amount of memory needed to query a view can vary depending on the complexity of the data manipulations that Tableau needs to perform to generate the marks in the view. Note: Only queries against extract data sources count toward query usage capacity. Queries against data sources that use live connections to the underlying data do not. However, queries against data sources that use live connections might be subject to other query usage capacity enforced by underlying databases.

Views that exceed one or both capacity types might be canceled to ensure enough system resources are available so that other views on the site can load.

Tips for optimizing visualization capacity

Views that exceed visualization capacity can indicate the queries that Tableau must run in order to generate the view might be too complex. In such cases, you can use the following tips to help optimize queries thereby minimizing the time it takes to load views on Tableau Online. Most tips require that you edit the data source or workbook and republish to Tableau Online for changes to take effect.

For more tips, see the Workbook Performance(Link opens in a new window) topic in the Tableau Help.

Use data source filters : When you add a filter on a data source, you reduce the amount of data that needs to be generated in the view. Reducing the amount of data can help minimize load times of views. For more information, see Filter Data from Data Sources(Link opens in a new window) in the Tableau Help.

Use context filters : Similar to data source filters, context filters reduce the data in the data source but at the sheet level. Context filters work independently of other filters and can significantly reduce the amount of data that needs to be generated in the view. Reducing the amount of data can help minimize load times of views. For more information, see Improve View Performance with Context Filters in the Tableau Help.

Decrease date ranges : As a rule, dates require more computing power than other types of data like numbers and Booleans. If the view contains date filters, you can reduce the date ranges or the number of dates that need to be generated to help minimize the load times of views.

Reduce marks: Because Tableau must calculate the marks in order to generate the view, the number of marks can impact how quickly the view can load. There are several ways you can reduce marks, including using some of the filters listed above or using sets to filter, custom SQL to aggregate data, and more. For more information, see Reduce the number of marks in the view(Link opens in a new window).

Job runtime capacity

Job runtime capacity is the period of time that a job, or an instance of a task type, is allowed to run before it’s canceled to help protect available system resources. Each site comes with job runtime capacities for the following job types:

Extract refreshes

Subscriptions

Flows

Metrics

Each extract refresh, subscription, or metrics job type has a maximum runtime of two hours (120 minutes or 7,200 seconds).

Note about flows: For sites that don’t have Data Management, the maximum runtime for flows jobs for a site is 60 minutes times the number of creator licenses up to a maximum of 24 hours. If your site has large flows workloads, consider purchasing Data Managementto get more capacity. For sites with Data Management, you can run flows for up to 24 hours per day per Resource Block. If you exceed the time limit no new jobs can be started until the next day. Additional capacity for concurrent flow jobs can be purchased. For more information, see Resource Blocks.

Note about extract refreshes: If a refresh job reaches its maximum runtime, you see a timeout error. For more information about the error and ways you can modify extracts to keep refresh jobs within the runtime capacity, see Time limit for extract refreshes.

Concurrent jobs capacity

Concurrent jobs capacity is the number of jobs, or instances of a task type that can run at the same time. Each site comes with concurrent capacities for the following job types:

Extract refreshes

Subscriptions

Flows

Metrics

You can find more information about the concurrent jobs capacity for each job type below.

Extract refreshes: A site has the capacity to refresh up to 10 extracts concurrently. Depending on available system resources, refresh jobs can run sequentially or in parallel. Jobs that count toward concurrent refresh capacity include scheduled refreshes, manual refreshes, extract creation, and command line or API calls that trigger refreshes, including appending data incrementally.

Subscriptions: A site has the capacity to run up to 10 subscriptions concurrently. Jobs that count toward concurrent subscriptions capacity include generating emails from subscriptions created through Tableau Online directly or API calls that generate the email subscriptions.

Flows: If licensed with Data Management, a site has a default capacity of 1 concurrent flow job per Resource Block. Resource Blocks support flow jobs. If not licensed with Data Management, a site has a default capacity of 1 concurrent flow job, which is the equivalent of having one resource block. If there are no resource blocks available when a flow job starts, the job goes into a queue to wait for a resource block to be available. Additional capacity for concurrent flow jobs can be purchased. For more information, see Resource Blocks. Each user can have a maximum of 4 active flow web editing sessions at one time. If more sessions are opened, the oldest session will be closed.

Metrics: Each site has the capacity to refresh up to 10 metrics concurrently. For more information about how metrics refresh, see Create and Troubleshoot Metrics.

Note: If a site exhausts its concurrent capacity for a job, other jobs that are in the queue remain in a pending state until one or more jobs have completed.

Daily jobs capacity

Daily jobs capacity is the number of shared hours each site can spend per Creator license a day to perform all jobs on the site. A server process, called backgrounder, initiates and performs these jobs. A site with more Creator licenses gets more daily jobs (backgrounder) capacity to meet the needs of a larger site population.

Each site comes with daily jobs (backgrounder) capacity to perform both extract refresh and metric refresh jobs.

For example:

If your site has… multiplied by the default time Daily jobs capacity 10 Creator licenses 8 hours Up to 80 hours/day 50 Creator licenses 8 hours Up to 400 hours/day

Daily jobs capacity resets each day at 24:00:00 UTC (coordinated universal time).

About extract refreshes

Refresh jobs that count toward daily jobs capacity include full and incremental refreshes and extract creation, which can be initiated by scheduled refreshes, manual refreshes, and certain command line or API calls.

Notes:

As long your site has time remaining in its daily refresh capacity, a refresh job will run regardless of the time it takes for that refresh job to complete.

Site admins receive email notifications when a site reaches 70%, 90%, and 100% of its daily refresh capacity.

If a site exhausts its daily refresh capacity, any future extract refreshes are canceled and email notifications are sent to content owners alerting them of the refresh cancellation.

Tips for optimizing extract refreshes capacity

If you’re managing an extract-heavy environment, Tableau recommends following some best practices to make the most efficient use of your site capacity.

Stop refreshing unused extracts . One of the best ways to reclaim capacity for your site is to stop automatic refreshes, either through schedules on Tableau Online or through scripts of extracts that aren’t being used. For more information about deleting a refresh schedule, see Manage Refresh Tasks.

Reduce the frequency of refreshes . Another method of reclaiming capacity for your site is to reduce the frequency of extract refreshes. For example, instead of refreshing an extract hourly, consider refreshing an extract daily or only during business hours when fresh data is most useful. For more information about changing a refresh schedule, see Manage Refresh Tasks.

Use incremental refreshes instead of full refreshes . To decrease the amount of time an extract takes to refresh, consider performing an incremental refresh of the extract instead a full refresh. For more information, see Schedule Refreshes on Tableau Online. Note: Changing from a full to an incremental refresh can be done from Tableau Online only if the extract was configured for incremental refresh in Tableau Desktop before the extract was published. For more information about incremental refreshes, see Configure an incremental extract refresh(Link opens in a new window) in the Tableau User Help.

Use live connections instead of extract connections . For views, dashboards, and workbooks whose data needs to be updated frequently, consider setting up the data source to use a live connection instead of an extract connection.

Optimize the data in the extract. Improving the performance of an extract can also help reduce the amount of time an extract takes to refresh. There are a number of changes you can make to the extract’s data to help its overall performance, such as removing unused fields, using filters to remove unused rows, changing date ranges, etc.

About metric refreshes

Metrics that rely on extract data sources refresh when their extract counterparts refresh and therefore count toward daily job capacity.

Note: Metrics that rely on live data sources refresh every 60 minutes and don’t count toward daily job capacity.

Jobs initiated by command line and API calls

In addition to daily jobs capacity described above, a site comes with designated jobs capacity for command line and API calls.

Note: If the number of calls exceed the command line or API calls capacity described above, you see one of the following errors: Unknown 429 or ApiCallError: 429000: Too Many Requests – Too many requests for ‘api.rest.refresh_extracts’. Please retry after 146 second(s).

Monitor capacity

There are a few tools you can use to help you monitor your site’s capacity: Jobs page and Admin views.

Jobs page

The Jobs page gives you detail about the unique instances of backgrounder tasks, called jobs, within the past 24 hours. You can use the jobs page to monitor extract refreshes, subscriptions, and flow jobs.

Sign in to Tableau Online using your site admin credentials. In the left navigation pane, click Jobs. From the filter drop-down menu, under Task Type, select the job type you want to monitor.

For more information on the Jobs page, see Managing Background Jobs in Tableau Online topic.

Admin views

Admin views help you monitor different types activity on your site. You can find more capacity usage information, using admin views, for the features listed below.

Storage: You can monitor your site’s storage capacity and check which workbooks, data sources, and flows take up the most space on your site using the “Stats for Space Usage” admin view. Select Site Status > Stats for Space Usage. Next to How Is Space Used on This Site, see the total storage capacity used on your site. Below What Workbooks, Data Sources and Flows Use the Most Space , see a list of your site’s content and their sizes. For more information on this admin view, see Stats for Space Usage topic.

Flows: You can monitor the performance of flow runs. Select Site Status > Flow Performance History. Using the dashboard, under Flow History, click on a mark to see details about the flows job. For more information about this admin view, see Performance of Flow Runs(Link opens in a new window) in the Tableau Prep Help.

Metrics: You can monitor your site’s metrics jobs by using the “Background Tasks for Non Extracts” admin view. Select Site Status > Background Tasks for Non Extracts, and then from the Tasks filter drop-down, select Update all metrics on a view check box. For more information about this admin view, see Background Tasks for Non Extracts.
