Hi, The current automatic schema registration may cause a loss of precision. The link below is an example: https://issues.apache.org/jira/projects/IOTDB/issues/IOTDB-886?filter=allopenissues . Currently, The schema of the numeric type will be registered as float automatically. If the num is integer and greater than 2^24, it may lose precision. I’m currently considering if this infer value is greater than 2^24, use double as the automatic schema. The pr is like: https://github.com/apache/iotdb/pull/1796. This plan is currently under discussion. Looking forward to your opinions.
Best, Wangminhao Gou
