Hello Weaviate Community! 🤗
Got data that’s eating up memory like there’s no tomorrow? We’ve got you.
The new Weaviate 1.33 release comes with compression enabled by default, giving you optimal memory usage and faster performance right out of the box.
This week, we’re exploring what’s new in 1.33, diving into native multi-tenancy, building multi-agent systems with Crew AI (plus a few cool events you don’t want to miss).
Product highlights
Check out our latest product updates. Or follow along in the #announcement channel in the Weaviate Community Slack.
Weaviate 1.33 is now available open source and on Weaviate Cloud.
It comes with quite some impressive performance improvements - let’s explore them together:
💾 Compression by default: 8-bit rotational quantization (RQ) is now enabled by default when creating new collections, ensuring optimal memory usage and faster performance out of the box. Try it now
🔒 OIDC group management: Leverage user groups defined in your identity provider (like Keycloak, Okta, or Auth0) to manage permissions in Weaviate automatically. Try it now
🌀 1-bit rotational quantization (RQ): This quantization technique provides massive (close to 32x) compression rates while maintaining good search quality. Read more
🛒 Server-side batch imports: Instead of manually tuning batch parameters on the client side, you can now let the server manage the data flow rate for optimal performance. Try the preview now
