A DevOps Engineer needs to change the default size for a tar file to 512 MB. Which option should be used to enable this configuration?

• A. Set Segment Cache Size property to 512 in Oak Segment TAR NodeStore Service configuration in Webconsole.
• B. Set NodeState Cache property to 512 in Apache Jackrabbit Oak Document NodeStore Service configuration in Webconsole.
• C. Set changesSize property to 512 in org.apache.jackrabbit.oak.plugins.document.DocumentNodeStoreService.config file.
• D. Set tarmk.size property to 512 in org.apache.jackrabbit.oak.segment.SegmentNodeStoreService.config file.

Answer: (D)

TarMK stores content in segment tar files, and the size of each tar file is determined by a specific configuration setting. To change the default tar file size to 512 MB, you configure the TarMK segment node store by setting the tarmk.size property to 512 in the SegmentNodeStoreService.config file. This directly controls how large each tar file can grow before a new one is created, influencing disk usage and I/O patterns. The other options adjust caches or settings for a different node store type, or relate to a property that does not impact tar file sizing, so they don’t achieve changing the tar file size. After making this change, a restart is typically needed for the new value to take effect.
