Revise asset and identity lookup memory usage behavior in

Prior to the release of Splunk Cloud Platform 8.0.2004, KV Store backed lookups do not respect the max_memtable_bytes setting. This means that KV Store backed lookups are always stored in memory on the indexer.

With the release of Splunk Cloud Platform 8.0.2004, KV Store backed lookups do respect the max_memtable_bytes setting. This means that a KV Store backed lookup is stored in memory until it exceeds the definition in the max_memtable_bytes setting.

You might experience the following behavior after upgrading. Using Splunk Enterprise 8.0 as an example, consider a KV Store lookup of 1 GB in size that is used as an automatic lookup, with max_memtable_bytes=25MB. If you upgrade to a Splunk Cloud Platform version of 8.0.2004 or higher, the 1 GB size exceeds the max_memtable_bytes setting, so an index file is created and the lookup occurs on disk, which is slower.

The default setting in Splunk Cloud Platform is max_memtable_bytes=100MB. Splunk Cloud Platform customers need to contact technical support if necessary to revise this behavior.

To revise this behavior in an on-premises environment, increase your max_memtable_bytes in the $SPLUNK_HOME/etc/system/local/limits.conf file. See lookup of limits.conf in the Splunk Enterprise Admin Manual.
