pinpoint 修改hbase表TTL值

参考文档

https://greatwqs.iteye.com/blog/1741330

缘起
Pinpoint接入业务监控后数据量大涨,平均每天Hbase数据增量20G左右,数据量太大,需要对数据进行定期清理,否则监控可用性降低,由于之前环境是由docker-compose部署,查到hbase可以修改表的ttl来清理数据,目前进入pinpoint-hbase容器操作,如果能在hbase表格生成时就修改ttl效果会更佳,该方法需要熟悉docker-compose里面pinpoint-web及pinpoint-hbase部署方法,后期跟进

操作步骤
查找出数据大的hbase表

root@990fb5560f64:/home/pinpoint/hbase/data/default# du -h |grep G
17G ./TraceV2
2.2G    ./ApplicationTraceIndex
19G .

24小时产生数据大概20G,发现其中TraceV2及ApplicationTraceIndex数据比较大,设置TTL分别为7Day及14Day

进入hbase修改表ttl
