How to reduce the batch size during analytics data aggregation

  • The following messages can appear in the log files during the analytics data aggregation process. This means that the batch has failed to be stored and will be split and retried. You can safely ignore the WARN messages, however if they appear very often, you can reduce the batch size as described in the Solution section.

    Note: If the message is logged at the ERROR level, the solution in this article is not applicable. Please contact Sitecore Support in this case.

    WARN SqlReportingStorageProvider: Could not store entire batch. Try to storing in smaller batches.
    Exception: System.Data.SqlClient.SqlException

  • To resolve this issue, try decreasing the maximumBatchSize value in the \App_Config\Sitecore\Marketing.xDB\Sitecore.Analytics.Processing.Aggregation.Services.config file:

    <aggregator type="Sitecore.Analytics.Aggregation.InteractionAggregationAgent, Sitecore.Analytics.Aggregation">
      ...
      <param desc="maximumBatchSize" type="Sitecore.Analytics.Core.ConfigurationHelper, Sitecore.Analytics.Core" factoryMethod="ToShort" arg0="32" />
      ...
    </aggregator>

    If you want to rebuild your reporting database, you can also decrease the same value for the <historyWorker> node:

    <historyWorker type="Sitecore.Analytics.Aggregation.Data.Processing.InteractionHistoryWorker, Sitecore.Analytics.Aggregation">
      <param desc="maximumBatchSize" type="Sitecore.Analytics.Core.ConfigurationHelper, Sitecore.Analytics.Core" factoryMethod="ToShort" arg0="16" />
    </historyWorker>
