I’ve read through the documentation and can’t seem to find what, if any, limitations there are on names for datasource, dimensions or metrics.
Looks like they must be UTF-8 strings and they are case sensitive since version 0.7, but that is as much as I have been able to figure out.
It is certainly possible that I missed something in the docs, if so, I apologize for the noise.
For the solution we have built around Druid, we are interested in knowing:
- what characters are allowed (or prohibited) in the names?
- what is the maximum length of a dimension, metric name or datasource?
Thanks in advance,
