Description
File: /release-8.1/partitioned-table.md
This statement needs to be removed.:
Currently, static pruning mode does not support plan cache for both prepared and non-prepared statements.
From the DMR 8.0 release:
Remove some limitations on execution plan cache #49161 @mjonss @qw4990
TiDB supports plan cache, which can effectively reduce the latency of OLTP systems and is important for performance.
