accessor: support tags

[iksaif]

• Start by optionally supporting tags in the accessor
• Then implement it for cassandra.

Can we be a bit more descriptive? Do we mean tags in a way similar to Prometheus?

[iksaif]

Yes, labels like prometheus. I haven't had time to really think about it but the idea would be able to support at least what prometheus needs: foo.bar{label1="foo",label2"="test"}

Do you plan to add original HTTP tagdb support to bg carbon cache plugin as tagdb option?

[iksaif]

I think you should already be able to use the original HTTP TagDB plugin, I never tried though.

[Petee87]

The http tagdb not working for me. I think the bg carbon plugin overwrite.
In
biggraphite/plugins/carbon.py
within
class BigGraphiteDatabase(database.TimeSeriesDatabase)
with
def tag(self, *metrics).

biggraphite - 0.14.2, graphite(web,carbon) - 1.1.2
