------------------------------------------
Summary: Lost writes when using lightweight transactions
Key: CASSANDRA-8446
URL: https://issues.apache.org/jira/browse/CASSANDRA-8446
Project: Cassandra
Issue Type: Bug
Components: API, Core
Environment: Cassandra 2.1.2 on Java(TM) SE Runtime Environment (build
1.7.0_65-b17)
Reporter: Jochen Zeischka
There's a serious problem when using lightweight transactions. Whenever th
cluster gets any load, write timeout exceptions start to occur and the client
has no way to know whether the write actually succeeded or not.
I a simple test (https://gist.github.com/anonymous/4c83f2962b57fce4c3df) this
results in large percentages of lost writes (0 - 50%, depending on the load).
The problem was described in
