Apologies for the double up email but here’s the stack trace I get from using
the 3.11 driver on a Cassandra 5 cluster using the vector type (I forgot to
include it in my previous email)
[cluster19-worker-1] ERROR c.datastax.driver.core.SchemaParser - Error parsing

Again know the best answer is probably to use 4.16 or newer in the driver. But
I’d expect some people to raise tickets for this after release

Subject: Cassandra 5 - Driver 3.11 support plans
EXTERNAL EMAIL - USE CAUTION when clicking links or attachments
Hi All,
Asking a bit of a silly question on this list I expect I already know the
answer to, but are there any plans to support the new vector datatype in the
3.11 version of the java driver
(https://github.com/apache/cassandra-java-driver)?
I assume the answer will be no, but it might be a good idea to have that
documented somewhere? I know this project has just been donated, so there’s a
never-ending list of things to-do, but with the upcoming 5.0 release it’d be
good to have an answer before the release (so users have some time to have a
look at how much work they’ll need to do to upgrade any apps to 4.16 or newer
of the driver).
Let me know if my question is unclear!
Thanks,
Jackson
