> When trying to SUM a column of type COUNTER, this error is returned:
> {noformat}
> InvalidRequest: code=2200 [Invalid query] message="Invalid call to function sum, none of its type signatures match (known type signatures: system.sum : (tinyint) -> tinyint, system.sum : (smallint) -> smallint, system.sum : (int) -> int, system.sum : (bigint) -> bigint, system.sum : (float) -> float, system.sum : (double) -> double, system.sum : (decimal) -> decimal, system.sum : (varint) -> varint)"
> {noformat}
> This might be relevant for other agg. functions.
> CQL for reproduction:
> {noformat}
> CREATE TABLE test (
>         key INT,
>         ctr COUNTER,
>         PRIMARY KEY (
>                 key
>         )
> );
> UPDATE test SET ctr = ctr + 1 WHERE key = 1;
> SELECT SUM(ctr) FROM test;
> {noformat}
