How does a memory resident database satisfy the D in ACID?
- scottostler 15y agoPresumably it writes to a transaction log, and is memory-resident in the same sense that Redis is. Which is to say that the dataset is kept entirely in memory, but also has a persistent representation on disk.
- jfoutz 15y agoIIRC happstack-state has a journaling system. You don't have the state on disk, but you can reconstruct it. you could also journal to a remote machine for a live failover.
