Iurii Gerzhedovich updated IGNITE-22061:
----------------------------------------
Component/s: (was: sql)
> Use compact representation of BigDecimal with large scale for integers /
> numbers with trailing zeros
> ----------------------------------------------------------------------------------------------------
>
> Key: IGNITE-22061
> URL: https://issues.apache.org/jira/browse/IGNITE-22061
> Project: Ignite
> Issue Type: Improvement
> Reporter: Maksim Zhuravkov
> Priority: Major
> Labels: ignite-3
>
> BigDecimals that represent integer numbers can take up a lot of space, when
> scale is specified:
> {code:java}
> BigDecimal dc = new BigDecimal("11111111").setScale(1024,
> RoundingMode.HALF_UP);
> System.out.println("Difference:");
> System.out.println(MarshallerUtil.sizeInBytes(dc) -
> dc.stripTrailingZeros().setScale(0,
> RoundingMode.HALF_UP).unscaledValue().toByteArray().length);
> {code}
> The code prints:
> {code}
> Difference:
> 427
> {code}
> Let's update BinaryTuple format to store such numbers in more compact form
> that does not store trailing zeros.
