maxFrequency
public java.lang.Double maxFrequency
Maximum update frequency constraint; a 0 value means that no frequency
limit should be set. It can only be used in order to lower
the frequency granted by the Metadata Adapter.
A null value means that no change of the update frequency constraint
is requested; it is useless, but reserved for future extensions.
The update frequency limit is obeyed only for MERGE, DISTINCT and COMMAND
Items mode; in the latter case, the limit only applies to consecutive UPDATE
events for the same key value.
If unfiltered dispatching has been requested for the Items, the change
will be refused.
- Edition Note:
- Note that a further global frequency limit is also imposed by the
Server, if it is running in Presto edition; by the way, this specific limit
also applies to RAW mode and to unfiltered dispatching.
