Apache Cassandra Acceleration With Apache Ignite

The integration uses Cassandra asynchronous queries for CacheStore batch operations such as such as loadAll(), writeAll() and deleteAll() to provide extremely high performance.

The integration automatically creates all necessary tables (and keyspaces) in Cassandra if they are absent. Also, it automatically detects all the necessary fields for Ignite key-value tuples that will be stored as POJOs, and creates an appropriate table structure. Thus you don’t need to care about the Cassandra DDL syntax for table creation and Java to Cassandra type mapping details.

You can optionally specify the settings (replication factor, replication strategy, bloom filter and etc.) for Cassandra tables and keyspaces which should be created.

Combines functionality of BLOB and POJO storage, allowing to specify how you prefer to store (as a BLOB or as a POJO) key-value tuples from your Ignite cache.

Supports standard Java and Kryo serialization for key-values which should be stored as BLOBs in Cassandra

Supports Cassandra secondary indexes (including custom indexes) through persistence configuration settings for particular Ignite cache or such settings could be detected automatically if you configured SQL Indexes by Annotations by using @QuerySqlField(index = true) annotation

Supports sort order for Cassandra cluster key fields through persistence configuration settings or such settings could be detected automatically if you are using @QuerySqlField(descending = true) annotation.

Supports affinity co-location for the POJO key classes having one of their fields annotated by @AffinityKeyMapped. In such a way, key-values tuples which were stored on one node in an Ignite cache will be also stored (co-located) on one node in Cassandra.
