node.js - Bulk insert into Postgres with brianc/node-postgres -


i have following code in nodejs uses pg (https://github.com/brianc/node-postgres) code create subscriptions employee such.

    client.query(       'insert subscriptions (subscription_guid, employer_guid, employee_guid)         values ($1,$2,$3)', [         datasetarr[0].subscription_guid,         datasetarr[0].employer_guid,         datasetarr[0].employee_guid       ],         function(err, result) {         done();          if (err) {           set_response(500, err, res);           logger.error('error running query', err);           return console.error('error running query', err);         }          logger.info('subscription created');         set_response(201);        });

as have noticed datasetarr array. create mass subscriptions more 1 employee @ time. not loop through array. there way out of box pg?

i did search same question, found no solution yet. async library simple use query several times, , necessary error handling.

may code variant helps. (for inserting 10.000 small json objects empty database took 6 sec).

function insertdata(item,callback) {   client.query('insert subscriptions (subscription_guid, employer_guid, employee_guid)        values ($1,$2,$3)', [         item.subscription_guid,         item.employer_guid,         item.employee_guid        ],    function(err,result) {     // return err async.each iterator     callback(err);   }) } async.each(datasetarr,insertdata,function(err) {   // release client pg module   done();   if (err) {     set_response(500, err, res);     logger.error('error running query', err);     return console.error('error running query', err);   }   logger.info('subscription created');   set_response(201); })

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
