Fault tolerance

QuasarDB is write-safe by default and can even sync every write to the disk for maximum reliability. With its transactional engine, QuasarDB makes it easy to reason about updates while giving you the same level of reliability you’ve enjoyed from relational databases. Thanks to its master-less design, QuasarDB can face the loss of nodes transparently. When a node joins back, QuasarDB will replay the log of events to guarantee consistency.
