ApexBase v1.27.0

2026-08-01

Compare with v1.26.0

• Optimize Arrow record batch processing for large, variable-length result sets, improving throughput for wide string and binary projections and reducing unnecessary materialization in Arrow conversion paths
• Add end-to-end support for large UTF-8 and binary values in Arrow-backed result batches, preserving correctness across to_arrow(), to_record_batches(), CREATE TABLE AS SELECT, and INSERT ... SELECT
• Improve JOIN and subquery execution so TopK-style lookups prune blob-heavy rows more effectively and keep qualified filters aligned with expected row semantics
• Introduce shared, mmap-backed table-epoch tracking so logical write invalidation is visible across processes and cached reads are invalidated more reliably after table mutations
• Strengthen on-demand storage projection and scan behavior for lazy column reads, including more precise pruning of unused columns and better handling of blob-aware reads
• Expand regression coverage for TopK parser/binding safety, join-filter behavior, blob projection, DML validation, and null/empty-value semantics
• Update the Rust crate and Python package version metadata to 1.27.0
