node.js - Nodejs Cassandra Client [node-cassandra-client] -

i tried connecting cassandra cluster [version 1.0.6] via nodejs using node-cassandra-client

this sample script

var connection = require('cassandra-client').connection; var con = new connection({host:'x.x.x.x', port:9160, keyspace:'stats', timeout:10000}); console.log(con); con.execute('update testcf ?=? key=?', ['cola', '1', '20120132'], function(err) { if (err) { console.log("failed"); } else { console.log("success"); } });

on executing script

"sys" module called "util". should have similar interface. node-cassandra-client.driver: connecting x.x.x.x:9160 {} { validators: {}, client: null, connectioninfo: { host: 'x.x.x.x', port: 9160, keyspace: 'stats', timeout: 10000 }, timeout: 10000 } node.js:201 throw e; // process.nexttick error, or 'error' event on first tick ^ typeerror: cannot phone call method 'execute_cql_query' of null @ [object object].execute (/home/tamil/workspace/testprojects/node-cass/node_modules/cassandra-client/lib/driver.js:367:17) @ object.<anonymous> (/home/tamil/workspace/testprojects/node-cass/index.js:5:5) @ module._compile (module.js:432:26) @ object..js (module.js:450:10) @ module.load (module.js:351:31) @ function._load (module.js:310:12) @ array.0 (module.js:470:10) @ eventemitter._tickcallback (node.js:192:40)

my nodetool stats

address dc rack status state load owns token x.x.x.x datacenter1 rack1 normal 1.03 mb 100.00% 0

what error reason? , need help prepare this

the client within connection null. need connect() first. here's illustration (ignores errors):

var con = new connection({host:'x.x.x.x', port:9160, keyspace:'stats', timeout:10000}); con.connect(function(err) { assert.iferror(err); con.execute('select count(*) testcf', [], function(err, rows) { con.close(function(err) { // you're done now. }); }); });

i recommend using async handle ordering of connct, query, close, etc.

node.js cassandra

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
