> Currently, we keep the metrics results in BQ in tables with a schema like
> this:
> timestamp | total_bytes | run_time | (possibly other BQ columns)
> every time we want to add a new column the schema has to be extended. This is
> not convenient given the fact that any load test can have different metrics
> stored. This in turn would cause multiple BQ tables each queried differently.
> We can provide a more generic schema, like so:
> test_id | timestamp | metric | value
> thanks to that, every metric, whatever it's name is, can be saved in the
> table as a separate row. This gives more elasticity in storing metrics and is
> still easy to query and plot.
