Pull request overview
Updates the ClickHouse event deduplication job to better handle small mutation batches by switching to single-pass duplicate discovery and chunked mutation dispatch, with safeguards against overly large discovery runs.
Changes:
- Replace multi-batch discovery loop with a single discovery query capped by
DISCOVERY_LIMIT - Dispatch DELETE mutations in smaller chunks via
MUTATION_BATCH_SIZE - Add ClickHouse query setting (
max_query_size) and update checkpoint/result metadata fields
