互联网搬砖笔记
近日，考虑到重构之前的系统，涉及到如何设计一个阻塞型RPC调用，场景如下：. Web Server A 想要call 在Web Server B的一个方法F，方法F执行操作为CURD虚拟机，其中启动VM与克隆VM需要花费数分钟级别的时间。 声明B的方法F为同步方法：A起一个Thread调用F，当成功执行后，执行对应业务逻辑。 A中维持一大堆的TCP连接，消耗大量TCP资源；同时，导致在不稳定的Network环境下，错误处理逻辑麻烦。 B的方法F为异步方法，A在调用的时候提前约定，或者传入CallBack URL接口以参数形式传入。类似于 third party login. 1 A在调用后立即返回，无需维持大量的TCP连接。 1 增加API的复杂层度，须为每个阻塞型API都创建一个CallBack接口，增大代码的维护难度。 1 通过MQ的方式，解耦了Server A与Server B，同时，接口数量大大减小。 2 同时，可以打开Log功能已备查验。 2 增加了Deploy成本，当然可以采取Brokerless的MQ如ZeroMQ等来实现。 Test Key":"1c3a2.",. 在KeepassHTT...

Software engineer, photographer, musician, space geek. Local Timezone Lookups by Coordinates with MariaDB. I recently wrote about performing local timezone lookups with PostGIS. While this has been working well for me for many months, it requires that I keep an instance of PostgreSQL running just for this one purpose. At the time of that post, the spatial support in MySQL was pretty broken, but this should be fixed in the recent stable release of MySQL 5.6.11 (I haven't tested it). And second, ". Local T...

Here was my Blog
Wie du gerade mitbekommen hast, ist mein Blog nicht mehr da. Ich habe mich entschlossen diesen zu löschen, da ich schon so lange keinen Mist mehr drin veröffentlich habe. Wenn du der Meinung bist, ich soll mein Blog wieder zum Leben erwecken, dann schreib mir eine Mail oder zwitschere mich an. Du kannst mich auch gerne bei Twitter folgen, wo ich zwar auch recht selten aktiv bin, Aber lesen tu ich da schon öfters als schreiben. Oder schau dir mein Blog. Über das Studium an der Fernuni Hagen an.
