## AI overview

This project update reports progress on fault-tolerant query execution, including automatic query retries, experimental task-level retries, and a proof-of-concept distributed exchange plugin. It also covers scheduling improvements, memory-aware resource allocation, adaptive task sizing, dynamic filtering, and retry support for Hive and Iceberg.

## Source excerpt

Over the last couple of months we've added support for full query retries, landed experimental support for task level retries and provided a proof of concept implementation of a distributed exchange plugin (description below). We are still working on improving scheduling algorithms as well as optimizing exchange plugin implementation to make the task level retries fully usable.
