从PostgreSQL到MySQL / MemSQL的流复制

[英]Streaming replication from PostgreSQL to MySQL/MemSQL

原文 2017-11-10 19:35:18 6 1 mysql/ database/ postgresql/ memsql

I have two database systems currently in use in production: the main PostgreSQL database, and another database ( MemSQL ) used primarily for analytical purposes. 我有两个当前正在生产中使用的数据库系统：主PostgreSQL数据库和另一个主要用于分析目的的数据库（ MemSQL ）。

Is there a way to setup streaming replication of some of the tables in PostgreSQL to MemSQL (a MySQL-compatible database) rowstores, assuming the tables on both databases have the same schema? 假设两个数据库中的表具有相同的架构，是否可以设置将PostgreSQL中某些表的流复制复制到MemSQL（与MySQL兼容的数据库）行存储的方法？

I do not think that there is a tool for that (yet) but there is one for limited MySQL to Postgres replication: 我认为还没有针对该工具的工具，但是有一种工具可以将MySQL限制为Postgres复制：

Maybe this can be adapted to work the other way. 也许可以将其调整为其他方式。

And you could always build your own little data shovel by using the NOTIFY/LISTEN feature of Postgres. 而且，您始终可以使用Postgres的NOTIFY / LISTEN功能来构建自己的小数据铲。
Which is probably only an option if you only have to copy a very simple set of data. 如果您只需要复制一组非常简单的数据，那么这可能只是一个选择。
