+ * {@link PTransform}s for reading and writing files containing Thrift encoded
data.
+ *
+ * <h3>Reading Thrift Files</h3>
+ *
+ * <p>For simple reading, use {@link ThriftIO#} with the desired file pattern
to read from.
+ *
+ * <p>For example:
+ *
+ * <pre>{@code
+ * PCollection<ExampleType> examples =
pipeline.apply(ThriftIO.read().from("/foo/bar/*"));
Review comment:
+1 to not have a `read()` , less 'useless' code to maintain, other File
based IOs only have it for historical reasons and we decided to deprecate
`readAll` transforms too to make FileIO.match + read composition more explicit
since it cover more cases.

> Add ThriftIO to Support IO for Thrift Files
> -------------------------------------------

> Key: BEAM-8561
> URL: https://issues.apache.org/jira/browse/BEAM-8561
> Project: Beam
> Issue Type: New Feature
> Components: io-java-files
> Reporter: Chris Larsen
> Assignee: Chris Larsen
> Priority: Major
> Time Spent: 13h
> Remaining Estimate: 0h
>
> Similar to AvroIO it would be very useful to support reading and writing
> to/from Thrift files with a native connector.
> Functionality would include:
> # read() - Reading from one or more Thrift files.
> # write() - Writing to one or more Thrift files.
