URL: https://github.com/apache/doris-mcp-server/pull/44
This PR introduces a `DorisSessionCache` to cache and reuse
`DorisConnection` objects in memory. This helps to reduce the overhead of
creating new connections, especially for frequently used system sessions like
"query" and "system", and avoid not calling release_connection leads to
`Connection acquisition timed out` when the number of connection pools reaches
the maximum value.
The PR #34 fixed the issue when calling the tool `exec_query`, but in the
codebase, a large number of other tools directly using get_connection ("query")
to get connection object but without calling the release_connection method will
cause the connection fail to be obtained after a certain number of times.
Key changes:
- Added `DorisSessionCache` class to manage the lifecycle of cached sessions.
- The cache is configurable to store system sessions, user sessions, or
both. By default, only system sessions are cached.
