执行了show data之后，会有统计数据，其中可用空间是如何计算的？

我的测试虚拟机总共加起来貌似1024G还差点

谁知道 doris 集成 springboot 连接池配置该怎么配？

@moutains

我现在使用中发现，就把它当作MySQL，驱动啥都一样，就端口不一样，话说回来MySQL也支持不同的端口啊，你就把它当作一个MySQL实例；试一试呢？

请问表结构支持binary类型的字段么？

请问一下 doris stream load 写入json文件，多条数据时，文件内容只能是json array的形式吗？我文件只有一条json object的能正常写入，多条json object的文件写入时，报错：Reason: Parse json data for JsonDoc failed. code = 2, error-info:The document root must not be followed by other values..

@imay 请问，Doris支持数据自动恢复吗？比如，我5个存储节点，三副本；一个服务器故障，这个服务器上的数据副本会在其它可用服务器上自动恢复吗？

请问一下 docker 安装了 doris，执行 sh build.sh，提示 flex version (2.5.37) must be greater than or equal to 2.6.0 要怎么处理

你的版本低了，应该是0.14.0是1.2，现在最新的要用1.3把

大家有没有遇到tablet两个小时涨了5k，磁盘空间占比涨的缺不多，总之tablet一直在涨，之前一直不到一万，但是过了一晚上就到四五万了，并且还在涨

解决了，原来是replace false删除表时不会删除分片导致的

各位大佬咨询一个问题：用docker搭建了一个FE、3个BE的集群。建了一张表插入几条数据查询没什么问题，插入十万条数据后通过主键ID作为条件可以进行单条数据的查询，但是一查询多条（select from table limit 10）整个集群的BE节点就会全部挂掉，客户端显示 ERROR 1064 (HY000): errCode = 2, detailMessage = there is no scanNode Backend. [10005: in black list(A error occurred: errorCode=2001 errorMessage:Channel inactive error!)] be.out的日志start time: Tue Apr 13 18:19:54 CST 2021

大家好，想问一下，

= Memory exceed limit. Spill sort, while getting next. Backend: IP、, fragment: 9d9b8624d3614309-991688cb186b0373 Used: 215901767372, Limit: 215899308032. You can change the limit by session variable exec_mem_limit.

这个执行内存，已经通过修改会话内存调成36G了

怎么这里还是报溢出？

经测试，这个215899308032 ，单位是bit
