I had same concern regarding HBase . So I also added metric to measure Hbase op time in flatmap (Basically complete flatmap op).

But did these timing make sense?) -- View this message in context: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Partitioner-is-spending-around-2-to-4-minutes-while-pushing-data-to-next-operator-tp13913p14040.html Sent from the Apache Flink User Mailing List archive. mailing list archive at Nabble.com.
