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.
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.
The vector-sets module is a part of Redis Core and is available by default,
just like any other data type in Redis.
As a result, when building Redis from the source, the vector-sets module
is also compiled as part of the Redis binary and loaded at server start-up.
This new data type added as a preview currently doesn't support
all the capabilities in Redis like:
32-bit OS
C99
Short-read that might end with memory leak
AOF rewirte
defrag
