Cassandra is an excellent choice for systems that Can't Lose Data. - real single-server durability (set CommitLogSync to "batch"), not just "hope it replicates somewhere before you lose power" - best multi-DC replication anywhere - immutable data files mean it's very difficult to introduce corruption bugs - SnapshotBeforeCompaction option allows taking a snapshot of all your data files before replacing them with newer ones, so you can roll back to just before any compaction (as long as you have enough disk space to hold the snapshots of course)
