What steps will reproduce the problem? 1. submit datapoints via telnet or REST API that contain a tag value with ':', example: "storage-schema-retentions" = "60s:1d"

What is the expected output? What do you see instead?

The REST API will return 204. The metric name will show up as valid in the UI but when trying to render a chart, 0 datapoints will be returned.

I am assuming this is because ':' is used as a delimiter in composite keys by the cassandra backend. I think this may work fine in the m2 backend, BTW.

I think the REST API should return error in this case so the user knows his/her datapoints were not actually stored.

This has been fixed in the latest release (0.9.1).
