# Tenant Rebalance Improvements **Draft PR - Design Implementation** This PR implements improvements to the tenant rebalance API to address current limitations around flexibility, observability, and ease of use. See [Design document](https://docs.google.com/document/d/1wHYR8nrHzFDLosHkSSSnJ5rPZCWiKrs9XYnboMQ179U/edit?tab=t.0) ## Key Changes ### API Enhancements - Add `allowTables` and `blockTables` parameters for granular table selection - Deprecate `parallelWhitelist`/`parallelBlacklist` in favor of unified parallel processing - Introduce auto table ordering dealing with the requirement of dimension table ### Improved Workflow - Unified parallel queue processing (removes sequential queue) - Add pre-check aggregation and tenant-level validation - Better progress tracking and job cancellation support ### Observability - Aggregated pre-check results across tables - Tenant-level summary metrics (tables to rebalance, estimated data movement, etc.) - Enhanced progress reporting with estimated completion times --- *This is a draft implementation of the design document. Further refinements and testing are needed before production readiness.* *The description is modified from the output from Claude Sonnet 4* -- This is an automated message from the Apache Git Service.
