Refactor: Unify execute functions in zarr_exec.rs (Phase 2)#15
Merged
Conversation
Extract common patterns from execute_remote, execute_virtualizarr, and execute_virtualizarr_with_adapter into shared helpers: - build_exec_projected_schema(): Common schema projection logic - AsyncReadParams: Encapsulates common async read parameters - execute_async_read(): Generic async execution with store setup closure This consolidates the repeated stream creation pattern: 1. Build projected schema 2. Create async stream with store setup 3. Call read_zarr_async 4. Collect batches and wrap in RecordBatchStreamAdapter Impact: -17 lines (132 additions, 149 deletions) with clearer separation of concerns. Each execute function now focuses only on its unique store setup logic. Part of: #5

Summary
Phase 2 of refactoring to eliminate duplicated code. This builds on Phase 1 (#13).
Note: This PR includes Phase 1 commits. After #13 is merged, this PR will auto-update to show only Phase 2 changes.
Phase 2 Changes
Extract common patterns from the three execute functions (
execute_remote,execute_virtualizarr,execute_virtualizarr_with_adapter) into shared helpers:build_exec_projected_schema()- Common schema projection logicAsyncReadParams- Encapsulates common async read parametersexecute_async_read()- Generic async execution with store setup closureThis consolidates the repeated stream creation pattern:
read_zarr_asyncRecordBatchStreamAdapterEach execute function now focuses only on its unique store setup logic.
