Summary: Built-in GRPC health checks in FlightServerBase Key: ARROW-17920 URL: https://issues.apache.org/jira/browse/ARROW-17920 Project: Apache Arrow Issue Type: Improvement Components: FlightRPC Affects Versions: 9.0.0 Reporter: Akshaya Annavajhala (AK) [ARROW-14440] [C++][FlightRPC] Add example of registering gRPC service on a Flight server - ASF JIRA (apache.org) Related to the above issue, a portion of the issue notes that currently it is impossible in python for a server implementing FSB to extend to other gRPC messages. While I haven't verified that claim, it seems to be valid. Complete composability in python of an arbitrary gRPC service + FlightServer might not be a goal, but rather one possible way to implement a useful production flightserver that responds appropriately to [k8s-style health probes|[https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/#define-a-liveness-command].] A concrete ask perhaps more idiomatic to FSB is overridable default implementations of [gRPC health check messages|[https://github.com/grpc/grpc/blob/master/doc/health-checking.md#grpc-health-checking-protocol],] which would allow "simple" python derivations of FlightServerBase to be served in production environments (including k8s above which is adding support for the generic gRPC health checking protocol). -- This message was sent by Atlassian Jira (v8.20.10#820010)
