> Key: BEAM-8098
> URL: https://issues.apache.org/jira/browse/BEAM-8098
> Project: Beam
> Issue Type: Improvement
> Components: io-java-gcp
> Reporter: Robin Qiu
> Assignee: Robin Qiu
> Priority: P3
> Fix For: 2.17.0

> Time Spent: 40m
> Remaining Estimate: 0h
>
> While working on [https://github.com/apache/beam/pull/9144], I realized there
> is a gap in BigQueryIO documentation on mapping between data types defined in
> BigQuery and in Beam SDK.
>
> For example, if a user reads a BYTES field from BigQuery into Beam, it will
> be represented as java.nio.ByteBuffer type in Beam Java SDK. The user will
> need to do an explicit type cast to ByteBuffer in order to use the data, but
> there is no easy way the user can know which type they should cast to, unless
> digging into BigQueryIO's implementation (Java - Avro - BigQuery).
