[jira] [Comment Edited] (FLINK-15122) Reusing record object in StreamTaskNetworkInput

Could you elaborate/rephrase what is the problem [~lzljs3620320] (I'm a bit confused by the ticket's description) and how would you suggest to fix the problem? I guess this is not a regression?

> Now blink's batch is forced to open object reusing, but the data read from the network is not reused, which will lead to a large GC of the batch job.
