Here are some further thoughts of comparison of Redis vs Erlang NOSQL databases: Couchbase Mnesia Riak
These are even more confusing but helps for resolution here:
Couchbase vs Redis
Couchbase master to master replication unique and also has no locking concepts!
SImple for Redis:
For example, if you were working on a high performance algorithmic trading and you were pulling ticker prices out of a firehose and needing to store them at an insane rate so they could be processed, Redis is exactly the kind of datastore you would want to turn to for that — definitely not Mongo, CouchDB or MySQL.
This is also outdated
Memcached vs. Couchbase:
We compared the performance of a standard Memcached (1.4.x) server with a Couchbase server (not version 2) and saw ~40% performance degradation with Couchbase. This is mainly because Couchbase doesn’t not serve all the items from in-memory.
Yeh to Redisl
But Memcached can also run over a multi-threaded architecture, so unless you shard your Redis dataset, Memcached should have performance advantages here.
That said, Redis supports pipelining, which is ~x5 faster than without pipelining, and Memcached doesn’t support pipelining capability.
Memory is cheap for this via a local server:
The one downside of Redis is the memory overhead. You need 2X RAM to store X data. Memcached is a little more efficient & transparent with memory organization – you can examine the slabs, etc.
This article could resell you on Couchbase:
It sounds like a NO to Mnesia:
- Erlang only interface
- Tables limited to 2GB
- Deadlock prevention scales poorly
- Network partitions are not automatically handled, must recombine tables automatically
Confused? Maybe I should start with Couchbase for the Erlang since it SHOULD be easier to integrate. I also like the lockless capability and they do cover all the major language bindings I want.
