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.
RFC: redb (embedded key-value store) nearing version 1.0

How do you compare this to sled? https://github.com/spacejam/sled6 projects | /r/rust | 10 May 2023
Sled uses bw-tree actually https://github.com/spacejam/sled/wiki/sled-architectural-outlook
Production grade databases in Rust

There is a valid argument to be made for threads over async in a large percentage of use cases where async is considered the default. If this is what you are referring to however, I don't think they ever referred to async as completely useless: https://github.com/spacejam/sled/issues/1123.14 projects | /r/rust | 21 Apr 2023
Best local database that works on all platforms including web?
6 projects | /r/FlutterDev | 2 Mar 2023
Have you looked into other pure-Rust databases as well, such as sled or GlueSQL which has an SQL interface on top of sled? I wonder how those would compare to Persy.
Are there any embedded databases that have multiple-process support?

I'm not sure what you need. Are these of any use? https://github.com/meilisearch/heed https://github.com/spacejam/sled
Some key-value storage engines in Rust
12 projects | /r/rust | 27 Dec 2022
Are there a demand for management system of embedded storage like RocksDB? I plan to build one in Rust as the language becoming a core of many popular databases but wonder if there’s a demand. Can’t find any similar project even in other languages.

There is also Sled but as I understand it that is being reworked to use the author's new DB core Marble
GreptimeDB: a new open source database designed for large-scale time-series data storage and processing, written in rust
3 projects | /r/rust | 16 Nov 2022
There are some databases like sled/FlashDB designed to be embedded to other applications even bare metal microcontrollers. But I do doubt the potential bussiness value of a pure embedded database.

In-memory vs. disk-based databases: Why do you need a larger than memory architecture?
3 projects | dev.to | 5 Sep 2023
Memgraph uses RocksDB as a key-value store for extending the capabilities of the in-memory database. Not to go into too many details about RocksDB, but let’s just briefly mention that it is based on a data structure called Log-Structured Merge-Tree (LSMT) (instead of B-Trees, typically the default option in databases), which are saved on disk and because of the design come with a much smaller write amplification than B-Trees.3 projects | dev.to | 5 Sep 2023
The in-memory version of Memgraph uses Delta storage to support multi-version concurrency control (MVCC). However, for larger-than-memory storage, we decided to use the Optimistic Concurrency Control Protocol (OCC) since we assumed conflicts would rarely happen, and we could make use of RocksDB’s transactions without dealing with the custom layer of complexity like in the case of Delta storage.
How RocksDB Works
2 projects | news.ycombinator.com | 19 Apr 2023
Tuning RocksDB well is a very very hard challenge, and one that I am happy to not do day to day anymore. RocksDB is very powerful but it comes with other very sharp edges. Compaction is one of those, and all answers are likely workload dependent.
If you are worried about write amplification then leveled compactions are sub-optimal. I would try the universal compaction.
What are the advantages of using Rust to develop KV databases？
2 projects | /r/rust | 22 Mar 2023
It's fairly challenging to write a KV database, and takes several years of development to get the balance right between performance and reliability and avoiding data loss. Maybe read through the documentation for RocksDB https://github.com/facebook/rocksdb/wiki/RocksDB-Overview and watch the video on why it was developed and that may give you an impression of what is involved.

LMDB is much more sain in the sense that it supports real ACID transactions instead of savepoints for RocksDB. The latter is heavy and consumes a lot more memory for a lot less read throughput. However, RocksDB has a much better parallel and concurrent write story, where you can merge entries with merge functions and therefore write from multiple CPUs.
