James Taylor commented on PHOENIX-1241:
---------------------------------------
If metics aren't typed, then I'd go back to the solution I proposed above to
declare a metric name in the SYSTEM.STATS table and convert it as it's
upserted. The "inferring type based on byte[]" is not viable IMHO.
I'll file an HTrace JIRA too - I think it's valuable to type metrics. After
all, it's mostly numeric data, so why take the number->string->number hit?
> Add typing to trace annotations

> URL: https://issues.apache.org/jira/browse/PHOENIX-1241
> Project: Phoenix
> Issue Type: Sub-task
> Affects Versions: 5.0.0, 4.1.1
> Reporter: Jesse Yates
> Fix For: 5.0.0, 4.1.1
>
>
> Currently traces only support storing string valued annotations - this works
> for known trace sources. However, phoenix will have trace annotations with
> specific types. We can improve the storage format to know about these custom
> types, rather than just storing strings, making the query interface more
> powerful.
