Kyoungha Min updated BEAM-9325:
-------------------------------
Description:
org.apache.beam.sdk.util.UnownedOutputStream does not override a method
`public void write(byte b[], int off, int len) throws IOException`
resulting in extremely slow writing speed.
This is because `java.io.FilteredOutputStream` does not provide proper method.

`public void write(byte b[], int off, int len) throws IOException`
resulting in extremely slow writing speed.
This is because `java.io.FilteredOutputStream` does not provide proper method.
The throughput degradation is significant enough to put it as bug.
Anything that uses `UnownedInputStream`, including
`CoderUtils.decodeFromByteArray`, `CoderUtils.decodeFromSafeStream` etc, are
extremely slow.
Issue Type: Improvement (was: Bug)
