2021.5 (Released on October 20th, 2021)

Overview

Indexima’s newest version – V2021.5 – is now available. This new version brings the following main new features:

Data catalog integration: Indexima is integrated with Apache Atlas data catalog and any data catalog using the same interface as Atlas. This integration allows metadata management and governance capabilities for organizations to build a catalog of their data assets connected to Indexima.
Indexima console enhancements: the console improves the catalog view, presenting all the schemas and tables, with the ability to sort the indexes as well as the ability to perform advanced filters on the tables.

Support for the SAP HANA in-memory database has been extended to take into account the specifics of HANA and simplify integration of this data source with Indexima.
Connection to Snowflake views as external sources: It is now possible to connect Indexima as an external table directly on a Snowflake view. This configuration allows extending the use cases of Indexima as a Snowflake acceleration tool.

Please note that release 1.7.10 reached the end of life support as described by our end of life policy
