Container Image Issue (v4.1.0)

Due to an unstable load order issue in the v4.1.0 container image, BE processes may fail to start reliably in container environments. Container environment users should NOT upgrade to v4.1.0. Please wait for v4.1.1, which includes the fix (#71825).

warning

Downgrade Notes

  • After upgrading StarRocks to v4.1, DO NOT downgrade to any v4.0 version below v4.0.6.

    Due to internal changes in data layout introduced in v4.1 (related to tablet splitting and distribution mechanisms), clusters upgraded to v4.1 may generate metadata and storage structures that are not fully compatible with earlier versions. As a result, downgrade from v4.1 is only supported to v4.0.6 or later. Downgrading to versions prior to v4.0.6 is not supported. This limitation is due to backward compatibility constraints in how earlier versions interpret tablet layout and distribution metadata.

4.1.0​

Release Date: April 13, 2026

Shared-data Architecture​

  • New Multi-Tenant Data Management

    Shared-data clusters now support range-based data distribution and automatic splitting and merging of tablets. Tablets can be automatically split when they become oversized or hotspots, without requiring schema changes, SQL modifications, or data re-ingestion. This feature can significantly improve usability, directly addressing data skew and hotspot issues in multi-tenant workloads. #65199 #66342 #67056 #67386 #68342 #68569 #66743 #67441 #68497 #68591 #66672 #69155

  • Large-Capacity Tablet Support (Phase 1)

    Enables shared-data clusters to host significantly more data per tablet, with a long-term target of 100 GB per tablet. Phase 1 introduces intra-tablet parallelism across the entire ingestion, Primary Key update, and Compaction pipeline, so a single Lake tablet no longer becomes a single-threaded bottleneck as it grows. Improvements include parallel Compaction within a single tablet (with segment-level splitting), parallel MemTable finalization, flush, and merge for Lake loading (including the load-spill path), tablet-internal parallel publish and parallel condition updates for Primary Key tables, and range-split / parallel / size-tiered Compaction for the cloud-native Primary Key index with remote-storage mapper file support. Together, these changes substantially reduce ingestion memory overhead, compaction amplification, and FE metadata pressure for large-tablet workloads. #66424 #66522 #66778 #66586 #67432 #67478 #67554 #66796 #67392 #67878 #65908 #68677 #68123 #69865

  • Added segment metadata filter for Lake tables to skip irrelevant segments based on sort key range during scans, reducing I/O for range-predicate queries. #68124

  • Supports fast cancel for Lake DeltaWriter, reducing latency for cancelled ingestion jobs in shared-data clusters. #68877
