Re: PLEASE READ ME! IMPORTANT!

Thank you Stefan. “ Other than that, I do not remember I have touched / worked with any other mentioned parameter she elaborated on between 4.0 and 4.1 so I can not comment on that.” Not sure what do you mean here as the parameters which are affected are all duration, data rate and data storage.

Re: UDF: adding custom jar to classpath

Hi Benjamin, Hi everybody, I found in the documentation that we should add "allow_insecure_udfs: true" and optionally "allow_extra_insecure_udfs: true" so that "enable_user_defined_functions_threads: false" is really taken into account (I understood like that). That would explain why my UDF still

Re: UDF: adding custom jar to classpath

Sorry, I found that allow_insecure_udfs and allow_extra_insecure_udfs have been introduced in 4.0.2 but I run 4.0.1, so that explains the error. So for 4.0.1 "enable_user_defined_functions_threads: false" should be enough, no advance on that I still don't know why my UDF does not compile then Le m

Re: UDF: adding custom jar to classpath

Hi Sebastian, Do you use the latest 4.0.3 version? Those options were added in 4.0.2 I believe, so if you try them with an earlier version - below message is what you would get as they didn’t exist. Best regards, Ekaterina On Wed, 6 Apr 2022 at 9:53, Sébastien Rebecchi wrote: > Hi Benjamin, Hi

Re: UDF: adding custom jar to classpath

Hi Ekaterina, I use 4.0.1. But as I said I added a jar in classpath (/usr/share/cassandra/lib/ folder on every node) and I see that the jar is loaded in the classpath from the Cassandra command line. And I have "enable_user_defined_functions: true" and "enable_user_defined_functions_threads: false

Re: UDF: adding custom jar to classpath

The property you are setting permits some kinds of privilege escalation, but by default classes outside of those pre-defined by the whitelist are not permitted. This is imposed here: https://github.com/apache/cassandra/blob/210793f943dc522161fd26b6192f38a5c83fa131/src/java/org/apache/cassandra/c

Re: UDF: adding custom jar to classpath

OK, that seems clear now :) I understood from our conversations that "enable_user_defined_functions_threads: false" would disable the UDF' specific class loader but it seems I understood wrongly, so the only way to use custom packages in UDF is to modify source code. Many thanks! Le mer. 6 avr. 2

Re: Podcast Interviews for Feathercast

Hi All A quick update - I am working with someone on a potential first Cassandra related podcast. We are just looking at the questions and interview format etc to see how that could work. Thanks Sharan On 2022/04/02 11:43:32 Mick Semb Wever wrote: > > > > > > For those who are not familiar wit

Re: Performance Engineering Track at ApacheCon NA?

Hi Paulo We have great news - the Performance Engineering track has been accepted so we will be looking to encourage and promote CFP submissions for it. We are also looking for reviewers to help us rate the submissions---if you are still interested in doing that. ;-) Thanks Sharan On 2022/03

Re: Podcast Interviews for Feathercast

Sharan, FWIW - Patrick and I are also working on putting together a Cassandra podcast in the near future. Perhaps we could work together? Drop me a message at aaron.plo...@datastax.com, and I'd be happy to set up some time to discuss. Thanks, Aaron On Wed, Apr 6, 2022 at 10:07 AM Sharan Foga

Re: JMX exposing non-standard java classes, to fix requires a breaking change

I would say keep the old ones and add new ones to be compatible in addition. Now your catch led me to more thinking and I think throwing ConfigurationException deserves more attention. I noticed in DatabaseDescriptor there are setters that are leaking it to JMX since cassandra-3.0. I am not sure wh

Re: Dropping Python 3.6 support in 4.1

This. RHEL8 is going to be around for a long while, so I'd say python-3.6 should not be dropped for a long while. 2029 EOL is the date I see on the RHEL8 Planning Guide[0].. I saw the RHEL7/CentOS7 comments earlier and immediately thought about RHEL8 and python-3.6, since I'm working in that O
