---------------------------------------------
Summary: Cassandra sstable generation ID's are a signed int which
might overflow
Key: CASSANDRA-21111
URL: https://issues.apache.org/jira/browse/CASSANDRA-21111
Project: Apache Cassandra
Issue Type: Bug
Reporter: Stefan Miklosovic
We need to triage this but this seems to be legit:
We have hit an issue with a cluster that where sstable generation ID’s for a
peer has incremented so high that it has overflowed, which has introduced a 2nd
dash into the file name. For example:
nb--2146021117-big-data.db
This caused an issue with our solution which is aimed to consolidate partition
statistics in the data set. The current version of the solution does not
recognise the possibility of sstable generation ID’s being a negative value -
which causes it to fail.
Workaround:
Rename all sstables in the table to “reset” the generation ID.
