Just yesterday it helped me again to identify exact places of performance problems in a long running job 🫰. APM and other tools were useless. Found exact places of N+1s, lines that load too many records, most popular SQL queries, redundant queries, etc. Highly recommend!.

Very happy about this change to rubocop Very often I see people use the `&.` operator without giving much thought. That change does a deeper analysis of the code and will help to reduce unneeded `&.`, making code nicer. I found 250 such cases in my app.

A nice optimization was merged, which makes Rails batching over whole (or almost whole) tables even faster. 🎉.

This is probably more costly than changing programming languages, because of existing users, but are there examples where people migrated from GraphQL back to REST API? Or wish to do the migration?. What is your experience with GraphQL so far as an implementer and/or a user?.

It is scary when idiots like musk have so much power and influence. In ideal world, such people must be isolated from society. Or, more likely, he writes such statements purposefully. Sorry, I hate tweeting about politics, but having this idiot on our planet is too much.

Is it reasonable to require sidekiq as a dependency for this to work? Or active job?. What other tools for large data migrations people use and find useful?.

Does anyone use bg data migrations from my online_migrations gem? Do you find it useful, useless for your use case? Please respond here or in github issues or DM. After testing on a large project, I realised there are some significant flaws in it and going to reimplement it. /1.

Instead of one style of writing blocks, there are now 2. While reading the code, instead of descriptive names, you now need to remember what this meaningless 'it' refers to each time. While this might work for trivial cases, it will be abused for chained calls and be a hell.

The future Rails 8.1 will help solve a popular problem many teams have - constant merge conflicts in the structure.sql file at the head of the versions list. You need to provide a custom formatter. If sorting by, e.g., hashes of versions, the conflicts now will be very rare.

A large achievement for me - I released my first ruby gem 2.5 years ago, and now I have 1 million downloads across all the gems created since then. Thank you for using them!🥹

Rails 8 will allow using custom columns when iterating in batches🤌. This is useful when the table's primary key is not sortable (uuid4), to better utilize compound indexes for performance, or you want to iterate in some custom order.
