Can’t create YCQL index with WHERE clause in YugabyteDB

Question

[Question posted by a user on YugabyteDB Community Slack]

Can somebody explain to me how to work with indexes metadata in YCQL? I found this article: https://docs.yugabyte.com/preview/api/ycql/ddl_create_index/.

And I can't create example INDEX with WHERE condition with this exception:

com.datastax.driver.core.exceptions.SyntaxError: Feature Not Supported
CREATE INDEX idx ON orders (warehouse_id) WHERE warehouse_id < 100
^^^^^^
 (ql error -14)

Server: YCQL 3.9.0 Driver: Yugabyte CQL Java Driver 3.8.2 YugabyteDB 2.4.4.0.

Answer 1

You need to upgrade to 2.6.x at a minimum to have that feature. After you upgrade you'll be able to create the index.
