>
> Ignite SQL attempts to derive partition from the query in certain cases and
> sends the map queries only to nodes which have those calculated partitions.
> Such queries are limited to contain equality conditions over key or affinity
> key columns at the left and constant or parameter at the right.
> When the type of argument does not match the column type, the calculation
> leads to wrong result.
> For example, the following query produces incomplete results when _key column
> is INTEGER and the argument is CHAR.
> select * from test where _key = ?
> However, this is valid and resultive query for H2, which does implicit
> conversion in such cases.
