-------------------------------
Summary: Cache Spark Connect Rust session server version
Key: SPARK-60679
URL: https://issues.apache.org/jira/browse/SPARK-60679
Project: Spark
Issue Type: Improvement
Components: Connect
Affects Versions: connect-rust-4.3.0
Reporter: DB Tsai
Assignee: DB Tsai
Fix For: connect-rust-4.3.0
Repeated SparkSession.version reads currently issue an AnalyzePlan SparkVersion
RPC on every access. Cache successful version resolution per session, matching
Python Connect behavior, while preserving failed-request retry and isolation
for new sessions. Validate RPC counts and client-only paired baseline/candidate
timings.
