Vykar Backup

A fast, encrypted, deduplicated backup tool written in Rust centered around a friendly YAML config file.

Inspired by BorgBackup, Borgmatic, Restic, and Rustic. Vykar uses its own on-disk format and is not compatible with Borg or Restic repositories.

What we learned from a 22-Day storage bug (and how we fixed it)

The kubernetes/ingress-nginx repository has finally been archived. It happened right on the KubeCon stage just a couple of hours ago.

P.S. Previously, we covered the recent ingress2gateway v1.0 release and some other related tools.

Firn

Firn is a high-performance, multi-tenant vector and full-text search engine backed by object storage (S3 / MinIO / R2 / GCS). It is designed as a credible open-source alternative to turbopuffer, proving that a professional-grade tiered storage architecture (RAM → NVMe → S3) is achievable entirely from open-source components.
The cost efficiency of S3 with the speed of local RAM. A multi-tenant vector and full-text search engine backed by S3. Built with LanceDB and Foyer for microsecond-scale search latency on top of object storage.

SlateDB

SlateDB is an embedded storage engine built as a log-structured merge-tree. Unlike traditional LSM-tree storage engines, SlateDB writes data to object storage (S3, GCS, ABS, MinIO, Tigris, and so on). Leveraging object storage allows SlateDB to provide bottomless storage capacity, high durability, and easy replication. The trade-off is that object storage has a higher latency and higher API cost than local disk.
