TL;DW: A report about testing eight different databases on a range of OSes and filesystems (including journaling filesystems) under a power failure condition and examined whether they were capable of recovering correctly.<p>All eight had problems. Most of the problems related to a lack of durability.<p>The eight databases were: TokyoCabinet, MariaDB, LightningDB, SQLLite, KVS-A, SQL-A, SQL-B and SQL-C.<p>I&#x27;m surprised to see SQLLite in there (I don&#x27;t know as much about the others) - as their test suite specifically includes simulating shutdowns such as these.
