Marvin Giessing updated ARROW-17372:
------------------------------------
Component/s: Parquet
> Arrow parquet go is missing Power (ppc64le) specific utils implementations
> --------------------------------------------------------------------------
>
> Key: ARROW-17372
> URL: https://issues.apache.org/jira/browse/ARROW-17372
> Project: Apache Arrow
> Issue Type: Bug
> Components: Go, Parquet
> Affects Versions: 8.0.0, 8.0.1
> Environment: Linux (RHEL) ppc64le
> Reporter: Marvin Giessing
> Priority: Major
>
> When trying to build the [feast go
> lib|https://github.com/feast-dev/feast/tree/master/go] on ppc64le it fails
> because parquet internal seems to miss even the basic (pure go
> implementations for ppc64le) files. Providing e.g. `bit_packing_ppc64le.go` &
> `unpack_bool_ppc64le.go` should solve this issue in the first place.
> It can then be enhanced by implementing the correct vector & matrix
> intrinsics for the Power architecture (e.g. VSX or MMA) in a second step.
> go build -mod=mod -buildmode=c-shared -tags cgo,ccalloc -o embedded_go.so .
> cmd had error: exit status 2 output:
> {code:java}
> github.com/apache/arrow/go/v8/parquet/internal/utils
> /root/go/pkg/mod/github.com/apache/arrow/go/v8@v8.0.0/parquet/internal/utils/bit_reader.go:230:18:

> /root/go/pkg/mod/github.com/apache/arrow/go/v8@v8.0.0/parquet/internal/utils/bit_reader.go:318:18:
> undefined: unpack32 {code}
> I tested this already locally (with success) and create an according PR.
