Lindorm:Limits

Last Updated:Aug 28, 2023

Lindorm is highly compatible with Cassandra Query Language (CQL). Take note of the following limits on syntax before you use CQL:

  • Lindorm does not support user-defined types (UDTs), user-defined functions (UDFs), and user-defined aggregates (UDAs).

  • Lindorm does not support materialized views.

  • Lindorm does not support triggers.

  • Lindorm does not support SSTable attached secondary indexes (SASI).

  • Data records cannot be deleted by range.

  • The BATCH operation is not supported.

  • Lindorm does not support the following data types: Collections, Duration, and Counter.

  • Clients cannot use a token aware policy to connect to Lindorm.

  • Apache Cassandra supports timestamps in microseconds. Lindorm supports timestamps in milliseconds. When you migrate data from Apache Cassandra to a Lindorm wide table, exclude the writeTime column of the data. A timestamp value in microseconds is much larger than a timestamp value in milliseconds. Lindorm determines the timestamp value in microseconds to be a future timestamp. This may cause various issues such as issues related to time to live (TTL), data deletion, and data updates.
