The ideal location for statistics sharing databases is a memory based filesystem. The default of /tmp is memory based on some Linux distributions, but not on most. /dev/shm is always a memory based filesystem.
Draft Release Note
If neither the environment variable ydb_statsdir, nor its predecessor, gtm_statsdir, is set, the environment variable initialization of ydb_env_set sets both to /dev/shm. In the event either or both are set, ydb_env_set ensures both have the same value, with $ydb_statsdir, if any, taking precedence over $gtm_statsdir. ydb_env_unset unsets the value of both.
