Hi Gerard, such a type of state is not yet supported, but on the roadmap. The feature is called Broadcast State. A description is in JIRA [1].
Best, Fabian [1] https://issues.apache.org/jira/browse/FLINK-4940 2017-07-03 17:50 GMT+02:00 gerardg <ger...@talaia.io>: > Hello, > > Is it possible to have managed operator state where all the parallel > operators know that they have the same state? Therefore, it would be only > snapshotted by one of them and in case of failure (or rescaling) all would > use that snapshot. > > For the rescaling case I guess I could use union redistribution and just > keep one of the elements of the list, but given the size of the state it > would be more efficient if this can be avoided. > > Thanks, > > Gerard > > > > -- > View this message in context: http://apache-flink-user- > mailing-list-archive.2336050.n4.nabble.com/Managed- > operator-state-treating-state-of-all-parallel-operators-as- > the-same-tp14102.html > Sent from the Apache Flink User Mailing List archive. mailing list archive > at Nabble.com. >
