pinpoint 修改hbase表TTL值

緣起
Pinpoint接入業務監控後數據量大漲，平均天天Hbase數據增量20G左右，數據量太大，須要對數據進行按期清理，不然監控可用性下降，因爲以前環境是由docker-compose部署，查到hbase能夠修改表的ttl來清理數據，目前進入pinpoint-hbase容器操做，若是能在hbase表格生成時就修改ttl效果會更佳，該方法須要熟悉docker-compose裏面pinpoint-web及pinpoint-hbase部署方法，後期跟進

操做步驟
查找出數據大的hbase表

19G .

24小時產生數據大概20G，發現其中TraceV2及ApplicationTraceIndex數據比較大，設置TTL分別爲7Day及14Day

進入hbase修改表ttl

備註

major_compact的操做目的
合併文件
清除刪除、過時、多餘版本的數據
提升讀寫數據的效率
