I need fast and reliable key-value store for Ruby. Is there anything like it already?
The requirement is for it to run wholly inside the Ruby process, not needing any outside processes.
It might be in-memory with explicit disk flushes.
It needs to have minimal value-for-key retrieval times, write times may be not so good.
The amount of data stored won’t be terrible, about few hundred thousand keys, each with ~1kb text value.
It turns out that the best option for me was to use plain Hash along with Marshal to serialize it to disk.
YAML is definitely too slow for that number of objects.
Thanks to @ian-armit for reinforcing my trust in the core Ruby libraries.
