@leventov Thanks for the PR! I will review but it will take me some time.
> Add ByteBufferDestionation.write(ByteBuffer) and write(byte[], int, int)

> Project: Log4j 2
> Issue Type: Improvement
> Reporter: Roman Leventov
>
> Existing ByteBufferDestination API: getByteBuffer() and drain() is designed
> so that synchronization couldn't be avoided. This doesn't allow to implement
> LOG4J2-928.
> Github PR: https://github.com/apache/logging-log4j2/pull/71
> Added methods: write(ByteBuffer data) and write(byte[] data, int offset, int
> length) are designed so that they should care about synchronization
> themselves, internally, if needed. They should also synchronize with possible
> concurrent users of the synchronized getByteBuffer() + drain() API.
> Nevertheless, it allows for ByteBufferDestination implementations to
> implement write() methods without lock-free.
> TextEncoderHelper (hence StringBuilderEncoder, which delegates it's logic to
> TextEncoderHelper) is changed so that it calls ByteBufferDestination.write()
> whenever possible. There is an expectation that most of encoded events fit
> the thread-local buffers, and write() could be called instead of writing to
> destination.getByteBuffer() with synchronization.
> The PR also includes a sanity improvement: uses ByteBuffer.arrayOffset() at
> some places.
