Arena is an arena memory allocator for eval types.

OrderByParams specifies the parameters for ordering.

UnsupportedCollationError represents the error where the comparison using provided collation is unsupported on vitess.

UntypedExpr is a translated expression that cannot be compiled ahead of time because it contains dynamic types.
