--------------------------------------
Summary: Get rid of ByteString in messages
Key: IGNITE-22561
URL: https://issues.apache.org/jira/browse/IGNITE-22561
Project: Ignite
Issue Type: Improvement
Reporter: Ivan Bessonov
Here I would include two types of improvements:
* {{@Marshallable ByteString}} - this pattern became obsolete long time ago.
{{ByteBuffer}} type is natively supported by the protocol, and it should
eliminate unnecessary data copying, potentioally making the system faster
* Pretty much the same thing, but for {{{}byte[]{}}}. It's used in classes
like {{{}org.apache.ignite.internal.metastorage.dsl.Operation{}}}. If we
migrate these properties to {{ByteBuffer}} then deserialization will become
significantly faster, but in order to utilize it we would have to change
internal metastorage implementation a little bit (like optimizing memory usage
in {{{}RocksDbKeyValueStorage#addDataToBatch{}}}).
If it requires too many changes then I propose doing it in a separate JIRA. My
assumption - it will not require too many changes, but we'll see.
