opentsdb do not support “{” in tags

[lanyyyy]

I want to write to opentsdb, but it do not support "{" and "}", how to resolve it ???

Well, the obvious answer is don't use a curly brace in your tags. The main reason it isn't supported is that the query parser is not that smart so escaping the curly braces isn't supported. I can flag this as a feature request but it doesn't seem likely to get done soon unless you or someone else in the community wants to submit a PR for it.

You could see if the normalize tag plugin works for you. I'm not sure if it would be hooked in before or after this validation. You could remove all the {} characters.

#1525

If this were my installation, I'd probably replace the {} with _ or something.

You could try adding the {} here:

opentsdb/src/core/Tags.java

Line 549 in 14ab3ef

public static void validateString(final String what, final String s) {

but it's not likely to work futher down in the pipeline. :)
