Why max value is 999? What is we have more metrics? If it is required can
we make it configurable?

> Project: Apache Drill
> Issue Type: New Feature
> Components: Storage - Other
> Reporter: Dmitriy Gavrilovych
> Assignee: Dmitriy Gavrilovych
> Labels: features
> Fix For: 1.12.0
>
>
> Storage plugin for OpenTSDB
> The plugin uses REST API to work with TSDB.
> Expected queries are listed below:
> SELECT * FROM openTSDB.`warp.speed.test`;
> Return all elements from warp.speed.test table with default aggregator SUM
> SELECT * FROM openTSDB.`(metric=warp.speed.test)`;
> Return all elements from (metric=warp.speed.test) table as a previous query,
> but with alternative FROM syntax
> SELECT * FROM openTSDB.`(metric=warp.speed.test, aggregator=avg)`;
> Return all elements from warp.speed.test table, but with the custom aggregator
> SELECT `timestamp`, sum(`aggregated value`) FROM
> openTSDB.`(metric=warp.speed.test, aggregator=avg)` GROUP BY `timestamp`;
> Return aggregated and grouped value by standard drill functions from
> warp.speed.test table, but with the custom aggregator
> SELECT * FROM openTSDB.`(metric=warp.speed.test, downsample=5m-avg)`
> Return data limited by downsample
