Jukka Zitting commented on OAK-1925:
------------------------------------
-0 Without more significant performance impact I'd be reluctant to add the
extra complexity and memory overhead. New data segments are already cached in
memory by the {{SegmentWriter}}, and in most cases access to new large binaries
isn't too performance-critical. Older content is accessed through the more
performance-optimized {{TarReader}} class.
> Use streamed io instead of RandomAccessFile in TarWriter

> TarWriter currently uses RandomAccessFile to
> * Write the tar entries
> * Read written entries
> The write however are currently sequential. It might be better to use
> streamed buffered io for the write and maintain an in memory cache of written
> tar entries to serve the reads.
