    Description

      Downstream Change Summary

      We added a new parameter to control SBE Plan Cache size.

      Description of Linked Ticket

      We will introduce a setParameter planCacheSize. It must take the value in one of the following formats:

      • An interval [0, 100). This indicates the maximum amount of memory that the system will allocate for the plan cache, expressed as a percentage of the system’s total physical memory. For example: "5%".
      • An integer value. This indicates the maximum amount of memory that the system will allocate for the plan cache, expressed in bytes, KB, MB or GB. For example, 1048576, "1024KB", "100MB", "1GB".

      Default is "5%".
