fileparsing - Process huge text file in java web application via UI upload or read from directory -


my web application needs process text file (size close 200mb) reading relevant data. text file needs processed monthly once, means contents of text file varies monthly. know best practice implement processing of text file.

  1. shall allow user upload 200mb file via application , process it?

  2. configure java webapplication read file predefined directory in tomcat server.(still present ui user initiate processing, e.g.'start processing')

i using jsapar library processing text file flat file fixed positions.

let me answer question myself.

a pointed out vikeng21 prefer 2nd option. implemented in such way that, have made folder in files placed configurable via property file. added options in gui displays files available system process, reading pre-configured folder property file. if there no files available in folder, gui displays absolute folder path customer needs place files, app can read , render file info. process link rendered against each file name, upon clicking on control transfers action class, reads file using java io framework , process same using jsapar library.

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
