Hi Jaydeep,Thanks for reaching out and for bumping this thread.This is probably not the answer you’re after, but mentioning as it may address the issue.C* 3.0.14 was released over five years ago, with many hundreds of important bug fixes landing since July 2017. These include fixes for issues that

Re: CASSANDRA-14227 removing the 2038 limit

A 2-3% increase in storage volume is roughly equivalent to giving up the gain from LZ4 -> LZ4HC, or a one to two-level bump in Zstandard compression levels. This regression could be very expensive for storage-bound use cases.From the perspective of storage overhead, the unsigned int approach sounds

Re: Should we change 4.1 to G1 and offheap_objects ?

I share David and Aleksey’s views on this. We shouldn’t make major defaults changes right before RC. Might be worth adding a release note recommending users try them, and that they may become default in a future release though. — Scott > On Nov 16, 2022, at 3:38 PM, David Capwell wr

Re: Should we change 4.1 to G1 and offheap_objects ?

We have precedent for changing defaults that have near-universal positive impact in patchlevel releases, yep. disk_access_mode: auto -> mmap_index_only comes to mind. - Scott > On Nov 16, 2022, at 6:49 PM, Derek Chen-Becker wrote: > > I'm fine with not including G1 in

Re: Should we change 4.1 to G1 and offheap_objects ?

Jon, thanks for flagging that I didn't get a reply to your question on the thread.My main point in this thread is that I don't think post-beta is an appropriate time for a major prop change like this in the release cycle. Ideally at this point in the release cycle, major contributors and large u

Re: [DISCUSS] Chronicle Queue's development model and a hypothetical replacement of the library

Agree with Benedict's proposal here. In circumstances when I've needed to capture and work with FQL, I've found it cumbersome to work with Chronicle. The dial-home functionality and release process changes put it over the top for me. – Scott On Sep 19, 2024, at 8:40 AM, Josh
