> Key: FLINK-7582
> URL: https://issues.apache.org/jira/browse/FLINK-7582
> Project: Flink
> Issue Type: Bug
> Components: Runtime / REST
> Affects Versions: 1.4.0
> Reporter: Chesnay Schepler
> Priority: Minor
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h

> The RestClient uses an executor for sending requests and parsing responses.
> Under heavy load, i.e. lots of requests being sent, the executor may be used
> exclusively for sending requests. The responses that are received by the
> netty threads are thus never parsed and are buffered in memory, until either
> requests stop coming in or all memory is used up.
> We should let the netty receiver thread do the parsing as well.
