--------------------------------------------
Summary: LWT leaves corrupted state
Key: CASSANDRA-12862
URL: https://issues.apache.org/jira/browse/CASSANDRA-12862
Project: Cassandra
Issue Type: Bug
Components: Core
Environment: Cassandra 2.1.16, 3-node cluster with RF=3,
NetworkTopology with 1 DC
Reporter: Artur Siekielski
When executing "INSERT ... IF NOT EXISTS" (with consistency LOCAL_QUORUM) while
the concurrency level is high (about 50 simultaneous threads doing inserts, for
the same partition key but different clustering keys) sometimes the INSERT
returns applied=False, but the subsequent SELECTs return no data. The corrupted
state is permanent - neither the INSERT or SELECTs succeed, making the PK
"locked".
I can easily reproduce this - for 100 simultaneous threads doing a single
insert I get 1-2 corruptions.
