This umbrella issue spans a new common-grpc module, Spark Connect protobuf compatibility, frontend and backend services, operations and sessions, integration tests based on SparkSQLEngine, and documentation. Start by reading the referenced Spark base.proto and SparkConnectClient.scala, then inspect the existing SparkSQLEngine integration tests. Done means the listed Spark Connect engine tasks, IT coverage, and docs are completed.
