Summary: Improved Compaction/Repair load for bulk writes
Key: CASSANALYTICS-39
URL: https://issues.apache.org/jira/browse/CASSANALYTICS-39
Project: Apache Cassandra Analytics
Issue Type: Task
Reporter: Doug Rohrer
Today, the bulk writer imports unrepaired SSTables into level 0, which causes a
significant amount of I/O during compaction and repair that could be avoided if
we could coordinate the import somehow. This would allow us to leverage
Cassandra’s knowledge of the current state of SSTables on-disk and the fact
that the Bulk Writer never produces overlapping SSTables to import them into a
higher level and, if all imports succeed for all replicas of a particular
range, mark them as repaired.
