In case of huge collections, 10k rows can > correspond to less than 1 minute of events, which make usage of > ExecuteInfluxDBQuery processor inconvenient. I suggest adding support for > chunking queries. Chunking can be used to return results in a stream of > smaller batches (each has a partial results up to a chunk size) rather than > as a single response. Chunking query can return an unlimited number of rows. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
