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

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
