 - This variable limits how many historical schema versions can be cached in a TiDB instance. The default value is `16`, which means that TiDB caches 16 historical schema versions by default.
 - Generally, you do not need to modify this variable. When the [Stale Read](/stale-read.md) feature is used and DDL operations are executed very frequently, it will cause the schema version to change very frequently. Consequently, when Stale Read tries to obtain schema information from a snapshot, it might take a lot of time to rebuild the information due to schema cache misses. In this case, you can increase the value of `tidb_schema_version_cache_limit` (for example, `32`) to avoid the problem of schema cache misses.
