gocql_gocql

gocql

The gocql package provides a database/sql driver for CQL, the Cassandra query language.

This package requires a recent version of Cassandra (≥ 1.2) that supports CQL 3.0 and the new native protocol. The native protocol is still considered beta and must be enabled manually in Cassandra 1.2 by setting "start_native_transport" to true in conf/cassandra.yaml.

Installation

go get github.com/tux21b/gocql

Example

db, err := sql.Open("gocql", "localhost:8000 keyspace=system")
// ...
rows, err := db.Query("SELECT keyspace_name FROM schema_keyspaces")
// ...
for rows.Next() {
     var keyspace string
     err = rows.Scan(&keyspace)
     // ...
     fmt.Println(keyspace)
}
if err := rows.Err(); err != nil {
    // ...
}

Please see gocql_test.go for some more advanced examples.

Features

• Modern Cassandra client that is based on Cassandra's new native protocol
• Compatible with Go's database/sql package
• Built-In support for UUIDs (version 1 and 4)
