Bohdan Siryk commented on CASSPYTHON-29:
----------------------------------------
Perhaps I wasn't clear, I'm +1 on the server side change. I just wanted to
highlight that the driver still might be used to connect to the server that
doesn't support constraints, so we should not be actually delayed from
implementing this.
> An additional question: if we knew that system_views.clients was very
> diligent about not printing control characters (or other unprintable content)
> would we even be having this discussion? It seems like that's where the focus
> should be rather than what the clients are sending.
[~bschoeni] discovered two problems that in tandem may cause resource
exhaustion, so this whole already brings results :)
> Allow user to specify arbitrary parameters for STARTUP message

> Key: CASSPYTHON-29
> URL: https://issues.apache.org/jira/browse/CASSPYTHON-29
> Project: Apache Cassandra Python driver
> Issue Type: Improvement
> Components: Core
> Reporter: Swathi Sekar
> Assignee: Bohdan Siryk
> Priority: Normal
> Fix For: 4.0.0
>
> Time Spent: 50m
> Remaining Estimate: 0h
>
> Modify the driver to allow sending arbitrary STARTUP message options.
> Proposed design:
> - Add `extra_startup_options` param to Cluster constructor.
> - Thread it through Cluster -> connection setup (cluster.py) ->
> StartupMessage.
> - Define clear precedence/conflict behavior when duplicate/conflicting
> options are passed into the StartupMessage constructor.
> *Note:*
> This Jira was originally created for sending the client's application name
> and version as `APPLICATION_NAME` /
> `APPLICATION_VERSION` options in the STARTUP message, which is tied to the
> now-defunct DataStax Insights offering.
> Since the Java driver (5.0.0) and eventually C/C++ driver (3.0.0) are
> removing withApplicationName()/withApplicationVersion() entirely, this ticket
> has been updated.
