Class ResultSetCacheConfig

java.lang.Object
  streamcruncher.api.ResultSetCacheConfig

All Implemented Interfaces:

java.io.Serializable

public class ResultSetCacheConfig
extends java.lang.Object
implements java.io.Serializable

The Kernel performs many operations inside its own Process. There are also a few operations that are performed inside the underlying Database. However, it interfaces seamlessly and transparently with the Database, which is also why the Query Language is an extension of SQL.

To improve performance and to reduce latency, the Kernel handles some of the Pre-Filter Queries on its own instead of going to the Database. In cases where the Pre-Filter references a Database Table - via the .. IN (SELECT .. FROM ..) or the NOT IN (SELECT .. FROM ..) clauses, the Kernel caches the results of those Sub-Queries. This class is used to specify how often the results of those Sub-Query fragments have to refreshed by the Kernel i.e how often it should be fetched from the Database. This class is Thread-safe.
