VRANDMEMBER had a bug when exactly two elements where present in the
vector set: we selected a fixed number of random paths to take, and this
will lead always to the same element. This PR should be kindly
back-ported to Redis 8.x.
This PR introduces "IN" overloading for strings in Vector Sets VSIM
FILTER expressions.
Now it is possible to do something like:
"foo" IN "foobar"
IN continues to work as usually if the second operand is an array,
checking for membership of the left operand.
Ping @rowantrollope that requested this feature. I'm evaluating if to
add glob matching functionalities via the `=~` operator but I need to do
an optimization round in our glob matching function probably. Glob
matching can be slower, at the same time the complexity of the greedy
search in the graph remains unchanged, so it may be a good idea to have
it.
Case insensitive search will be likely not be added however, since this
would require handling unicode that is kinda outside the scope of Redis
filters. The user is still able to perform `"foo" in "foobar" || "FOO"
in "foobar"` at least.
This changes improve a bit the Vector Sets tests:
* DB9 is used instead of the target DB. After a successful test the DB
is left empty.
* If the replica is not available, the replication tests are skipped
without errors but just a warning.
* Other refactoring stuff.
This PR introduces the initial configuration infrastructure for
vector-sets, along with a new option:
`vset-force-single-threaded-execution`. When enabled, it applies the
`NOTHREAD` flag to VSIM and disables the `CAS` option for VADD, thereby
enforcing single-threaded execution.
Note: This mode is not optimized for single-threaded performance.

Hi, as described, this implements WITHATTRIBS, a feature requested by a
few users, and indeed needed.
This was requested the first time by @rowantrollope but I was not sure
how to make it work with RESP2 and RESP3 in a clean way, hopefully
that's it.
The patch includes tests and documentation updates.
