我使用 HappyBase 作为 Python Thrift 客户端来连接到 HBase。
我正在扫描表格，需要在多列上使用过滤器。如何在 HappyBase 中实现这一点？Java 使用 Filterlist 提供了一个选项。

As specified on the github page, Happybase is using Thrift. You should use the same syntax as thrift.
On your scan function, you can specify a filter string :
SingleColumnValueFilter(‘’, ‘, , ‘’)
For example, if you need to scan all rows with the column blah:blouh = batman :
hbase_table.scan(filter="SingleColumnValueFilter ('blah','blouh',=,'regexstring:^batman$')")
You can use AND or OR to put several filters, just remember to surround everything with parenthesis.
Thrift Documentation : http://hbase.apache.org/book/thrift.html
Be careful when creating filters on string, you will have to use a specific comparator (like regexstring in my example).
