-----------------------------------
Summary: [Rust] [DataFusion] Implement DECIMAL type
Key: ARROW-10818
URL: https://issues.apache.org/jira/browse/ARROW-10818
Project: Apache Arrow
Issue Type: New Feature
Components: Rust, Rust - DataFusion
Reporter: Mike Seddon
The TPC-H benchmarks correctly specify that all MONEY columns are DECIMAL type
(precision and scale are not specified). We currently use `DataType::Float64`
which is much lighter than a true Decimal type.
To be a valid benchmark we need to ensure we support the same precision as the
reference implementation.
