Andrey Gura commented on IGNITE-6339:
-------------------------------------
Implementation is completed. {{MappedByteBuffer}} implementation is default now
and it can be switched to single writer thread using JVM argument:
{{-DIGNITE_WAL_MMAP=false}}.
All file operations are noninterruptible for {{MappedByteBuffer}} or performs
special thread in case of single writer thread.
TC looks good. Please review.
