Jialin Qiao commented on IOTDB-861:
-----------------------------------
Hi, we may need to consider how many failed reason here: (1) series not
registered (2) insertion data type conflicts with registered (3) when inferring
type, get boolean object from "1.23" will meet error.
The third scenario may hard to serialize.
How about using CSV like this, each series is stored as a CSV, the first line
is path, the second line is datatype. Then each value is a line. This may
tolerant all three cases. What do you think?
E.g.,
root.sg.a."a.,,,b"
INT32
1241
1.122
boolean
111
22141
