Known Issues

Multiexcerpt macro
nameCassKI1

Snaps in this Snap Pack display an exception (raised by the JDBC driver) when you query a map column that has a timestamp as the key.

Example

  1. Create a table containing a map whose key is a timestamp:
    CREATE COLUMNFAMILY t (userid text PRIMARY KEY, todo map<timestamp, text>);

  2. Insert values into the newly-created table.
    INSERT INTO t (userid, todo) VALUES ('a', {'2013-09-22T12:01:00.000+0000': 'text'});

  3. Once the insert operation succeeds, query the map column:
    SELECT userid, todo FROM t;

    The Snap displays the following exception:

    com.datastax.driver.core.exceptions.CodecNotFoundException:
    Codec not found for requested operation: [timestamp <-> java.sql.Timestamp]

Behavior change

The jOOQ upgrade for Cassandra Snap Pack done as part of 436patches25597 resulted in the following behavior changes:

  • Previously, when TTL (time to live) was queried using a Select statement without specifying it during data insertion or update, the Cassandra Snaps would display '0'. Now, they return 'null' in such cases.

  • Previously, the null values were stored as ‘0' in the INT datatype columns, now they are stored as 'null’.
