Increase Atlas Query Performance Configuration limit in Adobe Experience Manager

Last update: September 8, 2026

This article explains how to increase the Atlas Query Performance Configuration limit in Adobe Experience Manager (AEM) to support large document processing. The default getChannelGroupLimit value restricts the number of query results returned and may prevent large document operations from completing successfully. To resolve the issue, update the configuration to a higher value to allow processing of larger result sets.

Description description

Environment

Adobe Experience Manager (AEM), all versions

Issue/Symptoms

  • Large document processing fails due to the query result limit.
  • Large document operations do not complete successfully.
  • Processing is restricted by the default query result cap.
  • The getChannelGroupLimit setting limits the number of query results returned.

Root Cause

The default query result limit configured is too low to support large document processing workloads.

Resolution resolution

Follow the steps below to resolve the issue:

  1. Log in to the AEM Author instance OSGi Console. The typical URL is http://<host>:<port>/system/console/configMgr.
  2. Locate the Atlas Query Performance Configuration option.
  3. Find the getChannelGroupLimit parameter.
  4. Change the value from the default setting, typically 50, to a higher value such as 1000 to support large document processing.
  5. Save the configuration.
  6. Verify the resolution by confirming that large document processing completes successfully and is no longer limited by the query result cap.
