Aleksandr Chesnokov updated IGNITE-27393:
-----------------------------------------
Description:
Exclude {*}statisticsPartitionData{*}, *metastorage* and
*distributed.metastorage* system views from report
These system views are excluded from the standard performance report because
they generate an excessively large amount of low-level diagnostic data. This
data is typically only relevant for deep, targeted investigations into specific
storage or memory allocation issues and creates unnecessary overhead in a
general performance snapshot
* *metastorage* contains numerous internal records such as per-partition SQL
statistics obsolescence markers (stats.obs.*) and serialized internal objects,
resulting in large reports with little diagnostic value for runtime performance.
* *distributed.metastorage* includes large SQL statistics configuration
entries (sql.statobj.*) that can span thousands of columns per table and
significantly increase report size. The same information is available in a more
compact form via statistics.* system views.
