opened on Jun 30, 2026

Cyanoptera release will happen in fall 2026.
We need to prepare for release around a month before it happens.
Many APIs have been made deprecated, and we need to recheck
relative performance.

  • recheck filter pushdown, scalar function pushdown, and aggregate pushdown to check whether we still benefit from it.
  • Implement async file reader for Vortex as it's done for Parquet
