节俭hbase客户端 - 支持过滤器和协处理器 [英] thrift hbase client - support filters and coprocessors

问题描述

可悲的是，我的hbase客户端语言是Python，我现在使用的是基于节俭AFAIK的happybase。我知道节俭到目前为止还不支持过滤器，协处理器（如果我在这里错了，请纠正我）。有人能指出我有任何Jira项目，如果有的话我可以跟踪计划/进度？我只能从Hbase in Action中找到：

• Thrift服务器匹配新的Java API：
  https://issues.apache.org/jira/browse/HBASE-1744

jira / browse / HBASE-5600rel =nofollow> https://issues.apache.org/jira/browse/HBASE-5600

>

第一个看起来不像过滤器，第二个过滤器还没有更新很久。

解决方案

通过Thrift支持过滤器。这里有一个HappyBase例子：

$ $ p $ $ $ c $ table $ connection $ table
g = table.scan（filter = SingleColumnValueFilter（'f'，'column1'，=''substring：text'））
作为键，g中的数据：
打印数据

同时查看 Thrift book 获取有关各种过滤器及其配置的信息。

Sadly, My hbase client language is Python, I am using happybase for now which is based on thrift AFAIK. I know thrift so far is still not supporting filters, coprocessors (correct me if I am wrong here). Can some one point me any Jira items I can track the plan/progress if there is one? The only ones I can find is from "Hbase in Action":

• "Thrift server to match the new Java API": https://issues.apache.org/jira/browse/HBASE-1744

• "Make Endpoint Coprocessors Available from Thrift": https://issues.apache.org/jira/browse/HBASE-5600

The 1st one doesn't seem covering filters and the 2nd one hasn't been updated for a long while.

解决方案

Filters are supported through Thrift. Here's a HappyBase example:

table = connection.table("mytable")
g = table.scan(filter="SingleColumnValueFilter ('f', 'column1', =, 'substring:text')")
for key, data in g:
    print data

Also check out Thrift book for information on various filters and their configuration.
