>
> Through profiling the Avatica server, I noticed that we were spending some 
> time resizing an ArrayList while converting {{MetaResultSet}}'s to 
> {{ResultSetResponse}}'s. This was because we did not specify the capacity of 
> the {{ArrayList<ResultSetResponse>}} during construction despite knowing what 
> the capacity needed to be.
> We can avoid some costly array copies if we specify the capacity in the 
> constructor.
