I just raised CASSANDRA-19097 (4.0->5.0) to critical. Basically we fail 
to bootstrap correctly and even reading at ALL after bootstrapping fails 
to get the correct data. We didn't manage to repro and the failure looks 
recently-ish. Any help from anybody familiar with that area of the code 
welcomed.

Re: CASSANDRA-19268: Improve Cassandra compression performance using hardware accelerators

2024-01-23 Thread Dinesh Joshi 
Hi Shylaja,

If you'd like we can continue this on the ticket you opened. Here are my
concerns -

1. QPL Java Library[1] (JNI bindings to Intel's QPL) does not have any
license information on the repo. This needs to be corrected. Please see the
types of licenses we can use[2] for further information.

2. Can you describe how the compressor will behave when the cluster is made
up of heterogeneous hardware? For example, let's say we have a mix of
machines where some support Intel's IAA and some don't?

3. Does QPL have checksumming built in?

thanks,

Dinesh

Silly question but there was just a 4.0.12 release, should users avoid adopting 
that or is the concern more cantered around CI and testing? Does a 4.0.13 need 
to be considered?
