Hi, I would like to ask here before posting new bug. I am trying to make a simple system for distribution preallocated tickets between concurrent clients using C* LWTs. It is simply one partition containing tickets for one domain, client reads the first one and tries to delete it conditionally, success = it owns it, fail = try again..
It works well, but it starts to fail with WTEs under load. So I tried to make simple test with 16 concurrent threads competing for one row with 1000 cols. It was running on cluster with 5 C* 3.0.9 with default configuration, replication factor 3. Surprisingly, it failed immediately after few requests. It takes longer time with less threads, but even 2 clients are enough to crash it. I am wondering, if it Is problem in Cassandra or normal behaviour or bad use of LWT? Thanks, Jaroslav
