pinpoint 修改hbase表TTL值
操作步骤
查找出数据大的hbase表

major_compact的操作目的 合并文件 清除删除、过期、多余版本的数据 提高读写数据的效率 604800 7day describe 'TraceV2' disable 'TraceV2' alter 'TraceV2' , {NAME=>'S',TTL=>'604800'} enable 'TraceV2' disable 'TraceV2' major_compact 'TraceV2' 1209600 14day describe 'ApplicationTraceIndex' disable 'ApplicationTraceIndex' alter 'ApplicationTraceIndex' , {NAME=>'I',TTL=>'1209600'} enable 'ApplicationTraceIndex' disable 'ApplicationTraceIndex' major_compact 'ApplicationTraceIndex'
