[jira] [Updated] (BEAM-9740) User Defined Compression

     [ https://issues.apache.org/jira/browse/BEAM-9740?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Kyoungha Min updated BEAM-9740:
-------------------------------
    Description: 
Some users, including myself, have asked for various compression types support.

Currently, the `org.apache.beam.sdk.io.Compression` is an enum type, which cannot be overridden by users.

Split up the interface so that users can feed their own user-defined  ComrpessionFactory.

```

public interface CompressionFactory extends Serializable

{ ReadableByteChannel readDecompressed(ReadableByteChannel channel) throws IOException; WritableByteChannel writeCompressed(WritableByteChannel channel) throws IOException; String getSuggestedSuffix(); boolean isCompressed(String filename); }

```
