Scylla Features¶

The following are new features for Scylla Open Source 3.2.x

IPv6 support for client-to-node and node-to-node communication - Scylla now supports IPv6 Global Scope Addresses for all IPs: seeds, listen_address, broadcast_address etc. This functionality will be available for Scylla Manager in Scylla Manager 2.0.
CQL Like Operator - when used on SELECT statements informs Scylla that you are looking for a pattern match. The expression ‘column LIKE pattern’ yields true only if the entire column value matches the pattern.

The following are new features for Scylla Open Source 3.1.x

CQL Per Partition Limit - This new per partition limit further allows you to set the number of partitions returned as a result. You can mix both row limits and per partition limits in the same CQL statement.
Local Secondary Indexes - More efficient Secondary Index searches when the base table and index share the same partition key.
BYPASS CACHE - This CQL command introduced in Scylla Enterprise 2019.1.1, now available in open source, informs the database that the data being read is unlikely to be read again in the near future, and also was unlikely to have been read in the near past; therefore no attempt should be made to read it from the cache or to populate the cache with the data.
Large Cell / Collection Detector - Makes finding large partitions easier.
Nodetool toppartitions - Samples cluster writes and reads and reports the most active partitions in a specified table and time frame.
Row-level Repair - nodetool repair operation now uses row-level repair, adding additional granularity with repairs.
ALLOW FILTERING CQL Command that allows for server side data filtering that is not based on the primary key. Introduced in 3.0, this feature was further enhanced in version 3.1.

The following are new features for Scylla Open Source 3.0.x

Scylla Materialized Views - An alternate view table for finding a partition by the value of another column. Experimental in prior versions, this feature was made production ready in Scylla Open Source 3.0.
Global Secondary Indexes - A mechanism for allowing efficient searches on non-partition keys using Materialized Views. Experimental in prior versions, this feature was made production ready in Scylla Open Source 3.0.
Hinted Handoff - ensures availability and consistency
SSTable 3.0 - new SSTable format
ALLOW FILTERING CQL Command that allows for server side data filtering that is not based on the primary key.
