What is Tigris?
Tigris still ships features inside essays, and the newest one is a recycle bin.
The feed is a blog, not a changelog, and each post is an engineering argument that happens to carry a product change. This window has three: a recycle bin for objects and buckets built on immutable storage so deletion in a geo-replicated active-active system stops meaning data loss, agent-native onboarding via tigris init --agent, and a CLI that migrates an entire bucket from any S3-compatible provider in one command. The rest are essays on SigV4, presigned URLs, and ClickHouse restore economics.
What is Weaviate?
Weaviate is turning the vector database into an agent runtime with tunable search effort
The feed mixes real release notes with developer guides, and the release notes carry the weight. Recent work centers on the Query Agent rather than the storage engine: Search Mode now takes an effort tier, and query profiling exposes per-stage, per-shard timing. The 1.38 release moved the disk-based vector index and a built-in MCP server to general availability, alongside a rebuilt async replication scheduler.

Tigris

Tigris still ships features inside essays, and the newest one is a recycle bin.
◆ Current state
The feed is a blog, not a changelog, and each post is an engineering argument that happens to carry a product change. This window has three: a recycle bin for objects and buckets built on immutable storage so deletion in a geo-replicated active-active system stops meaning data loss, agent-native onboarding via tigris init --agent, and a CLI that migrates an entire bucket from any S3-compatible provider in one command. The rest are essays on SigV4, presigned URLs, and ClickHouse restore economics.
◆ Where it's heading
Two arguments run underneath everything: object storage should be the durable state layer for agents, and S3 compatibility is a surface to be explained rather than merely claimed. The SigV4 and presigned-URL posts are the second argument in practice — publishing where the protocol is dangerous is a credibility play against the incumbent. The recycle bin extends the immutability story into a place immutable systems usually struggle, which is undoing a mistake.
◆ Prediction
Expect more posts that pair a protocol critique with the Tigris behavior that answers it; the egress-cost framing from the ClickHouse post is the one most likely to recur as a paid migration path.
Weaviate
5.0DEVOPS
Weaviate is turning the vector database into an agent runtime with tunable search effort
◆ Current state
The feed mixes real release notes with developer guides, and the release notes carry the weight. Recent work centers on the Query Agent rather than the storage engine: Search Mode now takes an effort tier, and query profiling exposes per-stage, per-shard timing. The 1.38 release moved the disk-based vector index and a built-in MCP server to general availability, alongside a rebuilt async replication scheduler.
◆ Where it's heading
The center of gravity has shifted from storing vectors to running retrieval as an agentic service. Engram going generally available gave agents managed memory; the MCP server gave them a standard way in; effort tiers now let callers trade latency and cost for search quality on a per-query basis. Operability is being built out in parallel — profiling and replication work are what a database needs once agents, not humans, are issuing the queries.
◆ Prediction
Expect the effort tiers to spread beyond Search Mode into the rest of the Query Agent surface, and the two 1.38 previews — the Boost API and nested object filtering — to reach general availability in a following release.
