A. Sophie Blee-Goldman updated KAFKA-13152: ------------------------------------------- Summary: Replace "buffered.records.per.partition" & "cache.max.bytes.buffering" with "{cache}/{input.buffer.max.bytes}" (was: Replace "buffered.records.per.partition" with "input.buffer.max.bytes" ) > Replace "buffered.records.per.partition" & "cache.max.bytes.buffering" with > "{cache}/{input.buffer.max.bytes}" > -------------------------------------------------------------------------------------------------------------- > > Key: KAFKA-13152 > URL: https://issues.apache.org/jira/browse/KAFKA-13152 > Project: Kafka > Issue Type: Improvement > Components: streams > Reporter: Guozhang Wang > Assignee: Sagar Rao > Priority: Major > Labels: kip > > The current config "buffered.records.per.partition" controls how many records > in maximum to bookkeep, and hence it is exceed we would pause fetching from > this partition. However this config has two issues: > * It's a per-partition config, so the total memory consumed is dependent on > the dynamic number of partitions assigned. > * Record size could vary from case to case. > And hence it's hard to bound the memory usage for this buffering. We should > consider deprecating that config with a global, e.g. "input.buffer.max.bytes" > which controls how much bytes in total is allowed to be buffered. This is > doable since we buffer the raw records in <byte[], byte[]>. -- This message was sent by Atlassian Jira (v8.20.10#820010)
