The performance hit due to decoding the JSON is expected and there is not a lot (except for changing the encoding that I can do about that). Alright.
When joining the above stream with another stream I get another performance hit by ~80% so that in the end I have only 1k msgs/s remaining. Do you know how to improve that? Might setting the buffer size / timeout be worth exploring? -- View this message in context: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/Improving-Flink-Performance-tp11248p11272.html Sent from the Apache Flink User Mailing List archive. mailing list archive at Nabble.com.
