Zebra-MergeTable
================

[](#zebra-mergetable)

基于PHP实现的大表水平拆分，类似mysql合并表 一种不是很中肯的说法是，mysql能支持千万级别的数据，oracle能支持上亿级别的数据，超过这个级别，可能会出现性能瓶颈。

但实际应用场景中，我们经常会遇到如下情况：

- 时间积累，表体积变大，业务要求不能迁移历史数据，查询性能下降
- 表记录数不多，但体积很大，查询性能不好，例如文章、帖子表等
- 表体积过大，索引过多，造成写入成本很高

以上只是举几个简单的例子，这几个场景下，都是不允许删除数据的。

Zebra-MergeTable希望能够通过对表进行水平拆分的方式解决这些问题
---------------------------------------

[](#zebra-mergetable希望能够通过对表进行水平拆分的方式解决这些问题)

目标：

- 灵活的配置化拆表
- 透明的拆表逻辑，在上层看来，仍然在操作一张表
- 常用函数支持
- 高效结果合并、排序、运算

哪些是我们暂时不会考虑的：

- 独立于语言（暂时只支持PHP）
- 复杂运算，例如去重、平均数等（分布式运算难题）
