StateChangeLogMerger

object StateChangeLogMerger extends Logging

A utility that merges the state change logs (possibly obtained from different brokers and over multiple days).

This utility expects at least one of the following two arguments - 1. A list of state change log files 2. A regex to specify state change log file names.

This utility optionally also accepts the following arguments - 1. The topic whose state change logs should be merged 2. A list of partitions whose state change logs should be merged (can be specified only when the topic argument is explicitly specified) 3. Start time from when the logs should be merged 4. End time until when the logs should be merged
