-----------------------------------------
Assignee: Vladimir Ermakov
> 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
> Assignee: Vladimir Ermakov
> Priority: Major
> Labels: iep-54, ignite-3
> Fix For: 3.0.0-alpha3
>
> Original Estimate: 168h
> Remaining Estimate: 168h
>
> Let's extend native support for Numeric types.
> * 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(4) are better represented by
> {{byte}} and {{short}} and {{int}} types as their fixlen encoding takes
> exactly 1, 2, 4 bytes respectively.
> * Decimal is a direct mapping to BigDecimal value.
