------------------------------------------------
Summary: Implement repair quality test scenarios
Key: CASSANDRA-16245
URL: https://issues.apache.org/jira/browse/CASSANDRA-16245
Project: Cassandra
Issue Type: Task
Components: Test/dtest/java
Reporter: Alexander Dejanovski
Implement the following test scenarios in a new test suite for repair
integration testing with significant load:
Generate/restore a workload of ~100GB per node. Medusa should be considered to
create the initial backup which could then be restored from an S3 bucket to
speed up node population.
Data should on purpose require repair and be generated accordingly.
Perform repairs for a 3 nodes cluster with 4 cores each and 16GB-32GB RAM
(m5d.xlarge instances would be the most cost efficient type).
Repaired keyspaces will use RF=3 or RF=2 in some cases (the latter is for
subranges with different sets of replicas).
||Mode||Version||Settings||Checks||
|Full repair|trunk|Sequential + All token ranges|"No anticompaction
(repairedAt==0)
Out of sync ranges > 0
Subsequent run must show no out of sync range"|
|Full repair|trunk|Parallel + Primary range|"No anticompaction (repairedAt==0)
Out of sync ranges > 0
Subsequent run must show no out of sync range"|
|Full repair|trunk|Force terminate repair shortly after it was triggered|Repair
threads must be cleaned up|
|Subrange repair|trunk|Sequential + single token range|"No anticompaction
(repairedAt==0)
Out of sync ranges > 0
Subsequent run must show no out of sync range"|
|Subrange repair|trunk|Parallel + 10 token ranges which have the same
replicas|"No anticompaction (repairedAt == 0)
Out of sync ranges > 0
Subsequent run must show no out of sync range
A single repair session will handle all subranges at once"|
|Subrange repair|trunk|Parallel + 10 token ranges which have different
replicas|"No anticompaction (repairedAt==0)
Out of sync ranges > 0
Subsequent run must show no out of sync range
More than one repair session is triggered to process all subranges"|
|Subrange repair|trunk|"Single token range.
Force terminate repair shortly after it was triggered."|Repair threads must be
cleaned up|
|Incremental repair|trunk|"Parallel (mandatory)
No compaction during repair"|"Anticompaction status (repairedAt != 0) on all
SSTables
No pending repair on SSTables after completion (could require to wait a bit as
this will happen asynchronously)
Out of sync ranges > 0 + Subsequent run must show no out of sync range"|
|Incremental repair|trunk|"Parallel (mandatory)
Major compaction triggered during repair"|"Anticompaction status (repairedAt
!= 0) on all SSTables
No pending repair on SSTables after completion (could require to wait a bit as
this will happen asynchronously)
Out of sync ranges > 0 + Subsequent run must show no out of sync range"|
|Incremental repair|trunk|Force terminate repair shortly after it was
triggered.|Repair threads must be cleaned up|
