Which solution would help the client pool their data together?
This topic describes how site admins can configure and manage pooling for Bridge clients. Pooling allows clients across the site to load balance data freshness tasks for data sources or virtual connections that connect to private network data. Show
Configure poolingThe purpose of a pool is to distribute (or load balance) data freshness tasks among the available clients in a pool whose access is scoped to a domain within your private network. Pools map to domains, giving you the ability to dedicate pools to keeping specific data fresh and maintaining security by restricting access to protected domains in your private network. Although the client in the pool that performs the data freshness task is chosen at random, if for whatever reason a client can no longer perform the task, the task is automatically rerouted to another available client in the pool to handle the task. There is no additional intervention required from you or your users to support or manage the pool of clients. Pooling is optimized for keeping data sources or virtual connections that connect to data on one or more private networks fresh. Pooling support does not extend to data sources that use Bridge (legacy) schedules. In general, pooling is optimized for the following situations:
Before configuring the poolBefore you can configure a client pool for your site, review the following:
Note about user rolesOnly site admins, or users with either the Site Administrator or Site Administrator Creator role, can configure and maintain pooled clients. Regardless of the type of user authenticated into the client, only site admins can add new pools, add clients to a pool, remove clients from a pool, and monitor clients in a pool. Note about refresh jobsThe Jobs page can show you the completed, in progress, pending, canceled, and suspended all Bridge refresh jobs that use Online schedules. This includes refreshes for file-based and non-file based data sources. For more information, see About Bridge Refresh jobs. For more information about various ways you can monitor Bridge activity, see Monitor data freshness tasks. Step 1: Ensure clients can connect to the siteIn order for Bridge to work with your site, you must allow clients to authenticate to the site.
Step 2: Configure a poolPools, which require Bridge 2021.4 (or later) clients, help route live query and extract refresh jobs to the appropriate private network. Use pools to access data distributed across multiple private networks, enable extract refreshes for file-based data sources, and to support data freshness tasks for virtual connections.
After you have at least one pool configured, as part of the publishing process, Tableau Cloud associates certain data sources or virtual connections with Bridge and client pools automatically. Step 3: Specify a domain for a poolEach new pool requires a domain to be specified through the Private Network Allowlist. This information is required to enable Bridge access to data in the private network on behalf of Tableau Cloud. Using the allowlist, you must specify the domain names or IP addresses of the private network where you want to enable client access. Domain namesThe domain names that you specify in the allowlist are the server names used in the data source connection or virtual connection. In some cases, you can find the server name listed in the Connections tab of the data source page in Tableau Cloud. For example, to keep data sources like “Starbucks” up to date, you might specify “mssql.myco.lan” and “oracle.myco.lan” or “*.myco.lan” in the allowlist.
To keep data sources like "Fitness Challenge" up to date, specify "fitness-challenge" in the allowlist.
In other cases, the Connections tab might not list the server name. When the server name is not listed, consider working with the content owner to identify where the data is hosted and specify the server name in the allowlist when you have that information. As a temporary alternative, you can skip to Step 4: Add clients to a pool to assign clients to use the Default Pool instead. IP addressesInstead of domain names, you can specify IPv4 addresses in the allowlist. We recommend you specify IPv4 addresses in the allowlist if IPv4 addresses are used in the data source connections or virtual connections. Consider working with your content owners to get this information. If you don’t have that information, as a temporary alternative, you can skip to Step 4: Add clients to a pool to assign clients to use the Default Pool instead. Notes:
To map a domain to a pool, do the following:
Allowlist registry rulesUse the following rules when specifying the domains that you want to enable Bridge access to. This allows Bridge, on behalf of Tableau Cloud, to access the data on your private network to perform data freshness tasks. A domain enables Bridge to connect to both databases and file data hosted in that domain. Notes:
Allowlist registry examplesExample 1 - database data Suppose you want Bridge to do the following:
To enable Bridge to support these scenarios, you can map the domains to two pools (A and B) and block the third domain.
Example 2 - file data Suppose you have file data, C:\Shared\employees.csv, located on fileserv.myco.lan. To enable Bridge access to this data, map the domain of the machine to a pool. You can specify one of the following domains to a pool:
Note: The host machine must allow network access to the "Shared" folder. Step 4: Add clients to a poolFollow the procedure below to assign clients not already assigned to a pool. Note: To support data freshness tasks for all data, ensure clients in the pool are running Bridge 2021.4 (or later).
Troubleshoot poolingBridge Refresh jobs fail with one of the errors listed below. The following errors can be seen on the Jobs page and the Background Tasks for Non Extracts admin view.
Bridge clients are being signed out This issue can happen if you deploy a large number of clients under the same Windows services account. When there are more than 10 clients running under one Windows services account, account security measures can cause clients to be logged out. For more information, see Windows services account. Other potential pooling issues When trying to
diagnose issues related to pooling, consider reviewing the following log files for a client on the Bridge client machine: tabbridgeclijob_ Which solution would help the client pool their data together in Accenture?Answer: A cloud analytics solution would help the client pool their data together.
