> [Rust] Strongly-typed reading of Parquet data
> ---------------------------------------------
>
> Key: ARROW-4314
> URL: https://issues.apache.org/jira/browse/ARROW-4314
> Project: Apache Arrow
> Issue Type: New Feature
> Components: Rust
> Reporter: Alec Mocatta
> Priority: Major
> Labels: pull-request-available
> Time Spent: 11h 40m
> Remaining Estimate: 0h
>
> See the proposal I made on [~csun]'s repository
> [here|https://github.com/sunchao/parquet-rs/issues/205] for more details.
> This aims to let the user opt in to strong typing and substantial performance
> improvements (2x-7x, see
> [here|https://github.com/sunchao/parquet-rs/issues/205#issuecomment-446016254])
> by optionally specifying the type of the records that they are iterating
> over.
> It is currently a work in progress. All pre-existing tests succeed, bar those
> in src/record/api.rs which are commented out as they require reworking. Where
> relevant, pre-existing tests and benchmarks have been duplicated to make new
> strongly-typed tests and benchmarks, which all also succeed. I've tried to
> maintain pre-existing APIs where possible. Some changes have been made to
> better align with prior art in the Rust ecosystem.
> Any feedback while I continue working on it very welcome! Looking forward to
> hopefully seeing this merged when it's ready.
