Use BigInt lib for returning large numbers

See original GitHub issue

I understand that the LONG datatype can’t be larger than 64bit. It’d be great if you could return a number larger than 64 bit when aggregating numeric datatypes.

Problem description: When calculating the SUM of a LONG field, I get an exception: NotSerializableExceptionWrapper: arithmetic_exception: long overflow

Steps to reproduce: CREATE TABLE testa(aa LONG)

Run this query multiple times: INSERT INTO testa(aa) VALUES (8888888888888888888)

SELECT SUM(aa) FROM testa

I have tried to reproduce the same. Created a table with a attribute values of type lONG & added 150 records of values 9999999999999999. Tried to do an aggregation “SUM” on this particular table and got “ArthimeticException error”. Added the screenshot.

Also, I have started working on fixing it by refactoring the code to use BIGINT. I will create a PR soon and will share the link here and we can discuss further.

Look forward

We’ve implemented this by https://github.com/crate/crate/pull/10854, which will be part of the next CrateDB 4.4 feature release.
