Subject: [PATCH 02/13] vinyl: store tuple comparison hints in cache tree
Date: Tue,  2 Apr 2019 20:33:39 +0300	[thread overview]
Message-ID: <154c071f95b28770b810588e954decf87ad72d42.1554225074.git.vdavydov.dev@gmail.com> (raw)
In-Reply-To: <cover.1554225074.git.vdavydov.dev@gmail.com>
In-Reply-To: <cover.1554225074.git.vdavydov.dev@gmail.com>

This patch incorporates tuple comparison hints into vy_cache_tree,
similarly to how it was done in case of memtx_tree.

Apart from speeding up lookups, this is also needed for multikey index
support, because multikey indexes will reuse hints to store offsets of
indexed array entries.
