Subject: [PATCH 0/7] merge-ort: implement support for packing objects together
Date: Fri, 6 Oct 2023 18:01:39 -0400 [thread overview]
Message-ID: <cover.1696629697.git.me@ttaylorr.com> (raw)
(Based on the tip of 'eb/limit-bulk-checkin-to-blobs'.)
This series implements support for a new merge-tree option,
`--write-pack`, which causes any newly-written objects to be packed
together instead of being stored individually as loose.
The motivating use-case behind these changes is to better support
repositories who invoke merge-tree frequently, generating a potentially
large number of loose objects, resulting in a possible adverse effect on
performance.
The majority of the changes here are preparatory to refactor common
routines out of the bulk-checkin machinery to prepare for indexing
different types of objects whose contents can be held in-core.
Also worth noting is the relative ease this series can be adapted to
support the $NEW_HASH interop work in 'eb/hash-transition-rfc'. For more
details on the relatively small number of changes necessary to make that
work, see the log message of the second-to-last patch.
Thanks in advance for your review!
