Interface IQueryCacheInvalidator

Provides a method signature for invalidating and clearing a cache.

Namespace: Couchbase.Query

Assembly: Couchbase.NetClient.dll

Syntax

public interface IQueryCacheInvalidator

Methods

InvalidateQueryCache()

Invalidates and clears the query cache. This method can be used to explicitly clear the internal N1QL query cache. This cache will be filled with non-adhoc query statements (query plans) to speed up those subsequent executions. Triggering this method will wipe out the complete cache, which will not cause an interruption but rather all queries need to be re-prepared internally. This method is likely to be deprecated in the future once the server side query engine distributes its state throughout the cluster.

Declaration

int InvalidateQueryCache()

Returns

Type	Description
int	An int representing the size of the cache before it was cleared.
