It is a pretty common usecase for systems (e.g. InfluxDB 3.0) to ingest data and write it as parquet files and then only ready parquet files that we wrote (and this are well formed)

Doing utf8 validation in the parquet reader take a significant amount of time for string data, likely leading to proposals to improve it like

• Speed up Parquet utf8 validation #6667

However if the usecase is to speed up parquet data that is "trusted" maybe validating at all is unecessary.

Describe the solution you'd like
Add an unsafe parquet API to disable UTF8 validation during read for users

Describe alternatives you've considered
