Adapter that adds Cassandra support to orm2.
To enable this adapter, use the addAdapter method of orm2. Observe:
var orm = require('orm2');
orm.addAdapter(require('orm-cassandra-adapter'));Once you've enabled the adapter, you can create orm2 models using the cassandra:// scheme for
your database URI. A typical URI will have this syntax:
cassandra://username:password@/keyspace?hosts=host:port,host:port,host:port
Note the lack of a host in this URL; the host is ignored since Cassandra clients
may need to connect to multiple hosts. The hosts query string parameter takes a comma-separated
list of hostname:port values, with :port being optional (the default is :9042).
The following optional query string parameters are also available:
- staleTime: Time in milliseconds before trying to reconnect to a node.
- maxExecuteRetries: Maximum amount of times an execute can be retried using another connection, in case the server is unhealthy.
- getAConnectionTimeout: Maximum time in milliseconds to wait for a connection from the pool.
- poolSize: Number of connections to open for each host (default 1)
This adapter uses the node-cassandra-cql module for its database operations.
