--------------------------------------
Summary: Rename Remote Storage metrics to remove ambiguity
Key: KAFKA-15236
URL: https://issues.apache.org/jira/browse/KAFKA-15236
Project: Kafka
Issue Type: Sub-task
Reporter: Abhijeet Kumar
Assignee: Abhijeet Kumar
As per the Tiered Storage feature introduced in
[KIP-405|https://cwiki.apache.org/confluence/display/KAFKA/KIP-405%3A+Kafka+Tiered+Storage],
we added several metrics related to reads(from) and writes(to) for remote
storage. The naming convention that was followed is confusing to the users.
For eg. in regular Kafka, BytesIn means bytes *_written_* to the log, and
BytesOut means bytes *_read_* from the log. But with tiered storage, the
concepts are reversed.
* RemoteBytesIn means "Number of bytes *_read_* from remote storage per second"
* RemoteBytesOut means "Number of bytes _*written*_ to remote storage per
second"
We should rename the tiered storage related metrics to remove any ambiguity.
