Alexey Goncharuk updated IGNITE-13668:
--------------------------------------
Labels: iep-54 ignite-3 (was: )
> Implement Number(n) and Decimal native types
> --------------------------------------------
>
> Key: IGNITE-13668
> URL: https://issues.apache.org/jira/browse/IGNITE-13668
> Project: Ignite
> Issue Type: Improvement
> Reporter: Alexey Goncharuk
> Priority: Major
> Labels: iep-54, ignite-3
>
> Number( n ) is an {{n}}-bytes two-complement integer signed value encoded in
> the varlong style (so that Number(4) can be mapped to integer and Number(8)
> can be mapped to long during (de)serialization). Larger numbers can be
> represented as {{BigInteger}}. The Number( n ) is a varlen type, so it will
> take two additional bytes in the varlen table, so types smaller than
> Number(2) are better represented by {{byte}} and {{short}} types as their
> fixlen encoding takes exactly 1 and 2 bytes respectively.
> Decimal is a direct mapping to BigDecimal value.
