Streaming partition upsert for Delta tables, replacing delta-rs SQL MERGE
Project description
deltalite (Python package)
Thin pyo3 binding over deltalite-core, built with maturin and imported as
deltalite. See ../README.md for what deltalite is, why the
crate is split in two, how the wheel is built and consumed, the operational
knobs, and the pre-rollout conditions.
src/lib.rs— the pyo3 module:DeltaLiteTable.open(...).upsert(...),UpsertStats, and theDeltaLiteErrorexception hierarchy.tests/— the differential parity suite (delta-rs MERGE vs deltalite upsert) plus probe/operations/types/crash-redelivery/interop/planner tests.harness/— the two write paths and logical-content comparison the tests use.deltalite_planner.py— rough knob-tuning helper (concurrent upserts + pod memory in, suggested mpp/mpf/byte-budget out).bench/— test-data generation helpers shared by the tests.
