Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Meilisearch Expands Search Power with Arroy's Filtered Disk ANN
One of our top oss contributors is developing mimir as an embedded Meilisearch: https://github.com/GregoryConrad/mimir/tree/main/packages/mi...

Announcing mimir: brand new NoSQL database with typo-tolerant full-text search!
I'm excited to announce the first stable release of mimir, a brand new Dart & Flutter NoSQL database!

All local database options for Flutter
Hey! I’m the author of Mimir (https://pub.dev/packages/mimir). I think it could deserve a spot on there 🙂!

Rust lib for mobile (iOS, android)
I can’t help you with the gradle part. You’ll have to look up how to import AAR from local file system. I got it working with an ivy repo like this https://github.com/GregoryConrad/mimir/pull/89/files

Officially releasing the Cloud offering of Meilisearch - the most popular Rust search engine
I'm guessing you grabbed that milli_v1 part from mimir; if so, glad someone found it useful! :)

Which tech stack for full text searches?
If you’re looking for an on-device database, Mimir can do all of those (minus geo-queries, but those can be easily added because the support needed for them is already there). https://pub.dev/packages/mimir (disclosure: I’m the author)

-
Best offline searching package?
Take a look at mimir! It is a database that will do exactly want you want.
-
Any gotchas in using Isar database?
If you are looking for full-text search for your data (e.g., for a search bar in your app), I would recommend taking a look at mimir! Isar offers decent full-text search, but it is not typo-tolerant. mimir has typo-tolerant full-text search with 0 configuration necessary; simply add documents and search just works!

Supabase Acquires OrioleDB
hey hn, supabase ceo here
we've been fans of Oriole for a while now and have been long-time supporters
in case you're jumping straight to the comments: OrioleDB is a table storage extension for Postgres. it acts as a drop-in replacement for the default postgres storage engine using the Table Access Method APIs (pluggable storage). the storage engine changes the representation of table data on disk. its architecture is designed to take advantage of modern hardware like SSDs and NVRAM. it implements MVCC, the feature that allows allows multiple connected users to see different versions of the data depending on when their transaction started, via an UNDO log rather than tuple versioning.
one caveat: it requires several patches to the postgres core to expand on the type of features external storage engines extensions can implement. for this reason it could be a while before you see this land as a default engine on supabase. we will probably make it available as an option for customers who want to experiment - no timeline is decided yet.
finally, we have been working with the team on decoupled storage and compute [0]. this is experimental but promising, especially with some recent advances in S3 (specifically Express One Zone [1]). we have a demonstration in the blog post.
i'll message Alexander in case there are any technical questions

Jepsen: MySQL 8.0.34
When I saw "cloud native" I was expecting S3-ish the way Neon does it but they say it's experimental: https://github.com/orioledb/orioledb/blob/beta4/doc/usage.md... and for them to say "beta, don't use in production" and then a separate "experimental" label must make it really bad

When Did Postgres Become Cool?
There are some interesting things in development to potentially solve that problem.
Here's a recent HN submission about OrioleDB of the more promising ones: https://news.ycombinator.com/item?id=36740921

PostgreSQL: No More Vacuum, No More Bloat
https://github.com/orioledb/orioledb/blob/main/doc/arch.md
> - PostgreSQL is very conservative (maybe extremely) conservative about data safety (mostly achieved via fsync-ing at the right times), and that propagates through the IO stack, including SSD firmware, to cause slowdowns
This is why our first goal is to become pure extension. Becoming part of PostgreSQL would require test of time.
> - MVCC is very nice for concurrent access - the Oriole doc doesn't say with what concurrency are the graphs achieved
Good catch. I've added information about VM type and concurrency to the blog post.
> - The title of the Oriole doc and its intro text center about solving VACUUM, which is of course a good goal, but I don't think they show that the "square wave" graphs they achieve for PostgreSQL are really in majority caused by VACUUM. Other benchmarks, like Percona's (https://www.percona.com/blog/evaluating-checkpointing-in-pos...) don't yield this very distinctive square wave pattern.
Yes, it's true. The square patters is because of checkpointing. The reason of improvements here is actually not VACUUM, but modification of relevant indexes only (and row-level WAL, which decreases overall IO).

The Part of PostgreSQL We Hate the Most (Multi-Version Concurrency Control)
I took a look at https://github.com/orioledb/orioledb which is a project attempting to remedy some of Postgres' shortcomings, including MVCC. It looks like they're doing something similar to MySQL with a redo log, as well as some other optimizations. So maybe this is the answer.

Features I'd Like in PostgreSQL

Supabase-JS v2
sorry to underwhelm!
if you like Neon, then I imagine you like their database branching model? On Friday we announced[0] our 500K investment into OrioleDB, who are working on branching[1], with the plan to upstream these changes into Postgres core.
It would be possible for us to run a fork of Postgres today which supports branching, but our long-term view is that developers would prefer a non-forked version of Postgre (to mitigate any risk of lock-in). So we will work on adding branching to Postgres core in the background, which will be a benefit to the entire Postgres ecosystem.
