2022.1 (Released on January 26, 2022)


Indexima’s newest version – v2022.1 – is now available. This new version brings the following main new features:

Easy to use

  • Table memory footprint: Extension of the SHOW TABLECOUNT function in order to display all the attributes of the tables, as well as more detailed information on the state of the table, the rows awaiting commit, or the state of the tombstone memory of hyperindexes. This allows for a better understanding of the memory footprint and the need to run a COMPACT operation on the table.
  • Query memory footprint: new query filtering capabilities to quickly identify memory-consuming queries or subqueries.
  • Simplification of the synchronization process in external table mode: Warning message in case of non-consistency of table structures before starting any synchronization.

Easy to adopt

  • Denodo is now supported in external tables mode. It enables you to access Denodo as if it was a table in the database.
  • Data Catalog with Apache Atlas: Improve import process and support deletion in Atlas of non-existing items to simplify integration and bootstrap of catalog.
  • Extend Microsoft ADLS support: Support for ADLS Gen2 Blob Storage for Indexima warehouse and file load.
  • Extend CEPH support: Support for CEPH for Indexima warehouse and file load.
  • Pushdown on AWS Redshift: Support for pushdown functions on AWS Redshift / Postgres allowing the delegation of specific functions to Indexima.

Easy To Implement

  • Re-initialization process: Accelerate the process of resizing the cluster and reducing the risk of "split-brain" in case of failure detection and cluster reset.
  • Startup check: Improvement of the startup consistency checks and notifications, to alert your Indexima admin in case of incorrect partitioning parameters.
  • License is not part of the installation process anymore.

End of life support policy

Please note that releases 1.7.11 and 1.7.12 reached the end of life support as described by our end of life policy.

Detailed Release Note

Reminder: End of Static mode
