I am making an application in nodejs in which i have to create cassandra database through CQL.
I have tried to use helenus,cassandra-driver but didn't able to create keyspace through CQL.
I have also tried apollo-cassandra and also able to connect to DB and create keyspace and enter tuples but when we fire queries again after restarting the application then it is showing schime mis-match error.
Which nodejs driver for cassandra is simple and fully supported for CQL?
Datastax has an official driver in the companys github repo.
https://github.com/datastax/nodejs-driver
The driver is for Apache Cassandra. This driver works exclusively with the Cassandra Query Language version 3 (CQL3) and Cassandra's native protocol.
High level features:
It works really well and is actively mantained.
Another route (if you prefer not writing the query statement outright in your code) is CassanKnex, it uses the datastax driver to execute queries - usage:
var cassanKnex = require("cassanknex")({
connection: { // default is 'undefined'
contactPoints: ["10.0.0.2"]
},
exec: { // default is '{}'
prepare: false // default is 'true'
}
});
cassanKnex.on("ready", function (err) {
var qb.createKeyspace("cassanKnexy")
.withSimpleStrategy(1);
.exec(function(err, res) {
if (err)
console.error("error", err);
else
console.log("res", res);
});
}
});
