The PR implements the SharePartitionMetrics as defined in KIP-1103, with one change. The metric `FetchLockRatio` is defined as `Meter` in KIP but is implemented as `HIstogram`. There was a discussion about same on KIP-1103 discussion where we thought that `FetchLockRatio` is pre-aggregated but while implemeting the rate from `Meter` can go above 100 as `Meter` defines rate per time period. Hence it makes more sense to implement metric `FetchLockRatio` as `Histogram`. Reviewers: Andrew Schofield <aschofield@confluent.io> |
