Moped
Moped is MongoDB driver for Ruby, which exposes a simple, elegant, and (most importantly) fast and well tested API.
Overview
Replica Sets
Moped offers automated syncing with replica sets -- discovering available primary and secondary nodes and providing automatic failover when a node becomes unavailable.
Example
db = Moped::Session.new "127.0.0.1:27017", database: "moped"
db.drop
db[:people].insert([{ name: "John" }, { name: "Mary" }])
db[:people].find.sort(name: -1).first # => { name: "Mary" }
db[:people].find(name: "John").update(name: "Jonathan")
3.times.map do |i|
Thread.new do
db[:people].insert(seq: i)
end
end.each &:join
db.with(safe: true) do |db|
db.insert(name: "Sue")
end
Compatibility
Moped is tested against MRI 1.9.2, 1.9.3, 2.0.0, and JRuby (1.9).
