2021.2 (Released on May 3rd, 2021)


The version - V2021.2 - of Indexima is now available. This version offers :

Easy To Use & Optimized Memory

  • Big indexes (Preview)
    This new feature limits the memory impact of very high cardinality indexes. You can now define a size beyond which a Hyperindex is put on disk.
    It enables to free up the RAM to further improve the performance of the Indexima cluster.
  • Big requests (Preview)
    This mechanism makes it possible to limit the number of simultaneous requests with very high memory consumption.
    These "greedy" requests are placed on a dedicated queue and no longer have any impact on fast requests.
  • Memory Management
    Requests’ memory footprint has been improved. And, you can access all the details of queries and sub-queries.
  • Improved resilience:
    The system more easily detects desynchronization between nodes and reinitializes itself (meaning without administrator intervention) after a few SQL queries in error.

Easy To Adopt

  • Configuration management
    Configurations’ settings have been simplified with several parameters being automatically set up in order to facilitate Indexima’s implementation.
  • Analyzer
    The analyzer’s advanced customization has been updated to facilitate the set-up of automatic indexes’ creation. 

Easy To implement

New Documentation Site

  • New documentation site
    A new documentation site is now available. It will simplify the access to all resources you need, according to your configuration.
    You have an improvement. Don't hesitate to talk to your CSM.

Tests after an upgrade

Indexima Team recommends performing a health check after an upgrade. The script has been improved to check more operations and will take less time. Please upload the new Bench here.
