Summary: Request to port the DSE rebuild options to Cassandra
Key: CASSANDRA-17503
URL: https://issues.apache.org/jira/browse/CASSANDRA-17503
Project: Cassandra
Issue Type: New Feature
Reporter: Paul Ayers
Testing rebuild in C* 4.0.1, I ran into a scenario where 'nodetool rebuild' was
ran without any options in a new DC and the system.available_ranges_v2 table
was populated such that every subsequent run of 'nodetool rebuild <sourceDC>'
streamed no data.
The problem was that the first run looked at only the new DC so no data was
streamed, then the next run that provided the correct source DC still resulted
in no streamed data.
Once the system.available_ranges_v2 table was truncated, rebuild worked as
expected.
The request here is to include the same code that allows the following options
to be used in DSE so one could easily resolve this by using '-m reset' in a
similar scenario:
-m, --mode mode
* normal - conventional behavior, streams only ranges that are not already
locally available
* refetch - resets locally available ranges, streams all ranges but leaves
current data untouched
* reset - resets the locally available ranges, removes all locally present
data (like a TRUNCATE), streams all ranges
* reset-no-snapshot - (like reset) resets the locally available ranges,
removes all locally present data (like a TRUNCATE), streams all ranges but
prevents a snapshot even if auto_snapshot is enabled
