our company planning on transitioning redis aerospike, seeing strange issues missing requests (only 35% making callback function).
here code testing with:
var cluster = require('cluster'); var numcpus = require('os').cpus().length; if (cluster.ismaster) { (var = 0; < numcpus; i++) { var worker = cluster.fork(); } } else { var start = new date().gettime(); var requests = 0; var responses = 0; var aerospike = require('./node_modules/aerospike'); var status = aerospike.status; var client = aerospike.client({ hosts: [ { addr: '127.0.0.1', port: 3000 } ] }); function connect_cb( err, client) { if (err.code == status.aerospike_ok) { console.log("aerospike connection success") } } client.connect(connect_cb) setinterval(function(){ for(var i=0; i<50; i++) { var key = aerospike.key('dexi','toys','floor_'+i); requests++; client.get(key, function(err, rec, meta) { responses++; if ( err.code == status.aerospike_ok ) { } else { console.error('get error:', err); } }); } },10); setinterval(function(){ for(var i=0; i<50; i++) { var key = aerospike.key('dexi','toys','floor_'+i); var rec = { uid: 1000, // integer data stored in bin called "uid" name: "user_name", // string data stored in bin called "user_name" dob: { mm: 12, dd: 29, yy: 1995}, // map data stored (msgpack format) in bin called "dob" friends: [1001, 1002, 1003] }; var metadata = { ttl: 10000, gen: 0 }; client.put(key, rec, metadata, function(err) { switch ( err.code ) { case status.aerospike_ok: break; default: console.error("put error: " + err.message); exitcode = 1; break; } }); } },10); setinterval(function(){ var timespent = ( new date().gettime()) - start; console.log(requests, responses,timespent); },15000); } below console output seeing:
