DataStoreProfile

This type is a class for model objects.

Defines properties used by the default event data store. The default data store is the data store supplied by the event infrastructure.

Attributes Summary

queryThreshold : EInt The maximum number of events that can be read in a single queryEvents call. This setting is required to protect the integrity of the system. If a query attempts to read too many events from the database, an excessive amount of Java and RDBMS resources may be consumed. If this threshold is reached, the QueryThreshholdExceededException exception is thrown.

sqlCacheSize : EInt The maximum number of transformed XPath expressions that will be cached in memory. Once the threshold is reached, the least recently used expression is removed from the cache.

maxConnectionRetries : EInt The maximum number of times that the data store will attempt to obtain a connection from the connection pool.

maxPurgeTransactionSize : EInt When purging events from the database, the maximum number of events that can be deleted in a single transaction.

schemaName : EString The database schema that contains the CEI tables.
