Method Detail

canProcessTimerange

public boolean canProcessTimerange(org.joda.time.DateTime maxTimestamp,
                                   Set<String> processorDependencies)

Checks if the given event definitions have already processed events up to the given timestamp.

Parameters:

maxTimestamp - the max timestamp

processorDependencies - set of event definition IDs

Returns:

true if the given event definition IDs have processed events up to the given timestamp, false otherwise

hasMessagesIndexedUpTo

public boolean hasMessagesIndexedUpTo(org.joda.time.DateTime latestTimestamp)

Checks if messages up to the given timestamp are searchable in Elasticsearch. It looks at the latest receive timestamp that has been indexed by looking at the processing status maintained by ProcessingStatusRecorder.

Caveat: This only looks at the processing status and doesn't take the Elasticsearch index.refresh_interval into account!

Parameters:

latestTimestamp - the timestamp to check

Returns:

true if messages up to the given latestTimestamp have already been indexed, false otherwise
