最快的并发NOSQL数据库

Question

Which NOSQL DB can I use to have concurrent writes and read for around 2000 to 5000 users? I used MongoDB but that is not working as concurrency is not possible in mongoDB. And yes I want to use that NOSQL DB in my JAVA code.

Answer 1

您可以尝试Apache cassandra，它支持带有集群的大量并发写入。

Answer 2

we use Apache Cassandra quite successful, it's write optimated db solution, which has multiple client options http://wiki.apache.org/cassandra/ClientOptions , eg the Java Hector Client . Cassandra is made for horizontal scaling, so if the performance is unsufficiant we just add another node (server) and the performance goes up.

We do thousands of concurrent writes in one seconds and we haven't really started to scale horizontal.
