-----------------------------------------
Summary: 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
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.
