+## Troubleshooting {#troubleshooting}
+
+### 1. High Database CPU usage during Full Refresh
+
+Jobs syncing tables without a primary key can consume more CPU because rowid computation is done for the rows.
+
+**Solution:** For non-primary-key table jobs, if CPU usage is high, reduce `max_threads` in the source configuration or set it to the default value.

 5. **MongoDB delete pre-image capture -** <br/> Added support to capture the full document on delete events using `fullDocumentBeforeChange: "whenAvailable"` for MongoDB 6.0+ clusters with pre-images enabled, falling back to `_id`-only `documentKey` when pre-images are unavailable to preserve existing behaviour.
 
+6. **Optimized chunking strategies for MSSQL -** <br/> Adds faster and more efficient chunk planning for MSSQL full-load syncs. Uses page-level metadata to split tables without scanning them (SQL Server 2012+, requires `VIEW DATABASE STATE`; not supported on Azure SQL DB/MI). Falls back to statistical sampling when the primary strategy is unavailable.

 1. **Skip equality deletes for CDC inserts post-backfill -** <br/> Equality deletes are now skipped for CDC inserts once the backfill→CDC overlap window is complete, reducing unnecessary write overhead. A new `dedup_inserts` flag on the Iceberg `olake_2pc` table property tracks this — Java sets it to `true` on backfill commit, and Go clears it to `false` after the first successful CDC commit. This applies to both the Arrow and legacy gRPC writers.
