GS_GSC_MEMORY_DETAIL

GS_GSC_MEMORY_DETAIL displays the memory usage of the global system cache of the current process on the current node. The data is displayed only when GSC is enabled.

Note that the query is separated by the database memory context. Therefore, some memory statistics are missing. The memory context corresponding to the missing memory statistics is GlobalSysDBCache.

**Table 1** GS_GSC_MEMORY_DETAIL columns

db_id	text	Database ID.
totalsize	numeric	Total size of the shared memory, in bytes.
freesize	numeric	Remaining size of the shared memory, in bytes.
