Summary by CodeRabbit

  • Performance Improvements
    • Improved query execution with enhanced parallel processing, dynamic filtering, file-scan balancing, and sort pushdown.
    • Improved large-dataset handling by distributing files more effectively across available partitions.
    • Enabled more efficient TopK aggregations, repartitioning, and statistics-based query planning.
  • Reliability
    • Improved timestamp ordering detection so optimizations are applied only when safely supported.
    • Added validation for file balancing and timestamp-order handling.
    • Improved metadata handling across query modes for more consistent results.

Review Change Stack

Walkthrough

The update raises toolchain and query dependency versions, enables DataFusion execution options, balances manifest files, and advertises Parquet timestamp ordering only after metadata validation.

Changes

Query planning and partition ordering

Layer / File(s) Summary
Dependency and API compatibility
Cargo.toml, src/parseable/staging/reader.rs, src/parseable/streams.rs
Rust, Arrow, DataFusion, object_store, and Parquet versions are updated. Arrow IPC and bloom-filter calls use current APIs.
Execution configuration
src/query/mod.rs
Session state enables statistics collection and additional DataFusion execution and optimizer options. Explain plans retain their statistics setting. Manifest loading uses mode-specific metadata sources.
File balancing and ordering proof
src/query/stream_schema_provider.rs
Files are balanced largest-first. Timestamp ordering is reported only for descending, non-overlapping file ranges. Tests cover balancing and validation.
Conditional plan ordering propagation
src/query/stream_schema_provider.rs, src/query/listing_table_builder.rs
Hot-tier and snapshot Parquet plans receive ordering only when it is proven. Staging and listing plans do not advertise ordering or apply explicit timestamp sorting.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to df4ac

The query changes can advertise descending time ordering while nullable timestamps may not satisfy the promised NULLS LAST order, causing incorrectly ordered results when files are combined. This should be fixed or explicitly accepted before merge.

Poem

A rabbit checks each file with care,
And validates timestamps there.
Safe ranges keep their ordered sign,
While balanced groups align.
Query plans hop with settings bright.

Resolution

Add the required Description section. Include the goal, chosen solution and rationale, key code changes, test status, and whether comments and documentation were added. Remove or replace the outdated dependency versions so they match the patch, which upgrades DataFusion to 55.0.0 and Arrow to 59.2.0 rather than the versions currently listed in the description.

Do not advertise ordering unless null placement is proven.

file_groups_are_time_ordered checks only TypedStatistics::Int { min, max } and SortOrder::DescNullsLast. Column stores no null count or null placement. Time-partition fields and p_timestamp are nullable. A file can therefore contain trailing null timestamps before a file with older non-null timestamps, while output_ordered_by_time advertises DESC NULLS LAST with preserve_order(true). Track and validate null counts and placement, or enforce a non-null invariant for every non-final file. Add a regression test for this two-file case.
