2022.3 (Released on November 9, 2022) ​

Overview ​

Indexima’s newest version – v2022.3 – is now available. This new version brings the following main new features:

Easy to use ​

Analyzer precision: Improved query history sharing between nodes for a better analyzer performance.
Updated index parser to better eliminate similar proposed indexes.
Console resilience: Reduced console memory footprint for better reactivity.
Integrated new WebSocket reconnection mechanism to improve resilience.

Easy to adopt ​

Upgraded AWS S3 communication stack for improved performance and resilience when storing or loading from object storage (AWS S3 or CEPH).

Easy To Implement ​

New 'bucket splitting' parameters to better control data partitioning in order to accelerate load/commit.
Reduced memory footprint during big data load (>100Go) to improve performance up to 30% and scale up load capacity.
Improved resilience upon network failure: new timeout and retry mechanisms to better support some network incidents and prevent some split brain edge cases.
Orchestration Yarn: New parameters to have a fine-grained control of nodes constraints and locality relaxation on a large Yarn cluster.
