Expose ParseableSchemaProvider trait - #1775
Conversation
- metric counter for hottier files scanned - moved `SchemaProvider` behind a custom trait `ParseableSchemaProvider` - Lazy struct to add physical optimizer rules at runtime - moved functions around and made some pub - streaming adapter for flight data
- configure adaptive HTTP/2 flow-control windows for Flight and livetail servers and clients - enable TCP_NODELAY for Flight RPC channels - cap encoded Flight messages at 4 MiB instead of allowing unbounded message sizes - add a full-filter Parquet scan builder for callers that retain an exact FilterExec above the source - preserve the existing exact-time-only scan builder for staging and other restricted callers - add coverage for non-time predicates installed on ParquetSource - log streaming partition counts for query diagnostics

Included review availability: Your plan provides up to 8 included reviews per hour; 6 remain after this review. WalkthroughThe pull request adds configurable query gRPC metadata, reusable DataFusion and Arrow Flight APIs, HTTP/2 flow-control settings, hot-tier and storage metrics, public module exports, and metastore logging cleanup. ChangesQuery extensibility and scan construction
Hot-tier scan accounting
Query port metadata and gRPC transport
Storage metric windows
Metastore timing cleanup
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The change makes query_grpc_port required in metadata, but two metadata tests still use fixtures without that field, leaving the current head with failing tests; merge should wait until the fixtures are updated and checks pass.

723-723: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winUpdate the metadata JSON fixtures.
NodeMetadatanow requires and serializesquery_grpc_port. At Line 723, deserialization fails because the fixture omits this field. At Line 757, serialization includes this field, so the byte comparison fails.Add
"query_grpc_port":"8003"to both fixtures. UseNodeMetadata::from_byteswhen testing legacy metadata.Also applies to: 757-757
