Thank you Scott We are seeing it for all the tables (Filter, Data ..etc )
<path>/nb-1-big-Statistics.db.tmp (deleted) <path>/nb-3-big-Statistics.db.tmp (deleted) <path>/nb-2-big-Data.db (deleted) <path>/nb-2-big-Statistics.db.tmp (deleted) <path>/nb-2-big-Index.db (deleted) <path>/nb-2-big-Statistics.db.tmp (deleted) <path>/nb-2-big-CompressionInfo.db (deleted) <path>/nb-2-big-Filter.db (deleted) <path>/nb-2-big-Summary.db (deleted) <path>/nb-2-big-Digest.crc32 (deleted) Also I believe the property `disk_access_mode` is only present in the DSE version of cassandra and we use Open source.
