gocql

GoCQL automatically discovers all data centers, racks and hosts in your cluster manages a pool of connections to them and distributes queries in a reasonable and efficient way. Automatic and safe type conversion between Cassandra and Go without any loss of precision. Basic types, collections and UUIDs are supported by default and custom types can implement their own marshaling logic. Synchronous API with an asynchronous and concurrent back-end. Each connection can handle up to 128 concurrent queries and may receive server-side push events at any time. Iterate over large results sets and let GoCQL fetch one page after another. The next page is automatically pre-fetched in the background once the iterator has passed a certain threshold. Trace queries to obtain a detailed output of all events that happened during the query execution from Cassandra. The output might help to identify bugs and performance bottlenecks in your application.
