For Apama queries and applications that do not involve caching (such as store and "system of record" use cases), the TCStore driver is now the recommended driver for the distributed MemoryStore. See TCStore (Terracotta) driver details. See also Configuring the TCStore driver.

Apama continues to support the BigMemory Max driver. This is still the recommended driver for caching use cases, but no longer for queries. See BigMemory Max driver details.

Support for using BigMemory Max for Apama queries is deprecated and will be removed in a future release. It is recommended that you now use Terracotta DB's TCStore for queries.

In the Distributed MemoryStore Configuration Wizard of Software AG Designer, when you select the third-party cache provider from the Store provider drop-down list box, you can no longer select the option Apama Queries (using BigMemory). This option has been replaced by the Apama Queries (using TCStore) option. See also Adding a distributed store to a project.

If you still want to use BigMemory Max for queries in new projects, you must now select BigMemory as the store provider and specify ApamaQueriesStore as the store name. See also Configuring the BigMemory Max driver. Existing deployments using BigMemory Max for queries are unaffected; this only covers developing new projects in Software AG Designer.

For detailed information on how to change a queries project that uses BigMemory Max to use TCStore instead, see Migrating from BigMemory Max to TCStore.

See also Deploying and Managing Queries, which provides detailed information on how to use queries with the distributed MemoryStore.
