java - jooQ spring boot Multiple Schema(Read Write Split) -


i want use jooq spring boot. have master slave architecture, want use jooq master slave architecture (master write & slave read).

how should proceed. using pom.xml configure jooq

<configuration>     <jdbc>         <driver>com.mysql.jdbc.driver</driver>         <url>${datasource.primary.url}</url>         <user>${datasource.primary.username}</user>         <password>${datasource.primary.password}</password>     </jdbc>     <generator>         <name>org.jooq.util.defaultgenerator</name>         <database>             <name>org.jooq.util.mysql.mysqldatabase</name>             <includes>.*</includes>             <excludes/>             <inputschema>jpa</inputschema>         </database>         <generate>             <deprecated>false</deprecated>         </generate>         <target>             <packagename>com.gensrc.model</packagename>             <directory>src/main/java</directory>         </target>     </generator> </configuration>

and autowiring dslcontext

but how change code now.

from comments:

i want route write queries master & read queries slave.

i'm not sure hard distinction between write=master, read=slave idea. sometimes, need read master within same transaction boundaries (i.e. read uncommitted data), in case of sending read query slave yield wrong results.

so, best place implement routing have separate datasource instances , inject them jooq accordingly. you'll separating master , slave in service layer explicitly, transparently jooq.

you could, of course, implement original requirement using jooq executelistener , providing jooq right jdbc connection depending on query type (executecontext.type()), again, think break quite soon.

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
