      Description

      When running wutool -selftest, I get a lot of warnings from the Cassandra driver:

      15:04:58.442 cassandra: WARN - Server-side warning: Unlogged batch covering 16 partitions detected against tables [hpcc.wuvariables, hpcc.wugraphprogress, hpcc.wufieldusage, hpcc.wuexceptions, hpcc.wufilesread, hpcc.wuqueries, hpcc.wugraphstate, hpcc.filessearchvalues, hpcc.workunits, hpcc.workunitssearch, hpcc.wustatistics, hpcc.wufileswritten, hpcc.wuresults, hpcc.wugraphs, hpcc.wugraphrunning, hpcc.wutemporaries]. You should use a logged batch for atomicity, or asynchronous writes for performance.
      15:04:55.291 cassandra: WARN - Server-side warning: Batch of prepared statements for [hpcc.workunitssearch, hpcc.wuexceptions, hpcc.filessearchvalues, hpcc.uniquesearchvalues, hpcc.workunits] is of size 9249, exceeding specified threshold of 5120 by 4129.
