What is NebulaGraph?

A graph database spending its releases on query-language parity and traversal speed.

NebulaGraph is a distributed graph database whose recent releases read as steady engine work rather than repositioning. The v3.x line has been filling in query-language gaps — shortest-path variants, INNER JOIN, UDFs, richer rounding and JSON handling — while the bulk of each changelog goes to traversal performance, RocksDB tuning, and Raft/leader-balance stability. Nothing in the entries points at a managed service, an AI/vector story, or a pricing change.

What is Rivet?

Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.

Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.

NebulaGraph vs Rivet: editorial side-by-side

N5.0

A graph database spending its releases on query-language parity and traversal speed.

◆ Current state

NebulaGraph is a distributed graph database whose recent releases read as steady engine work rather than repositioning. The v3.x line has been filling in query-language gaps — shortest-path variants, INNER JOIN, UDFs, richer rounding and JSON handling — while the bulk of each changelog goes to traversal performance, RocksDB tuning, and Raft/leader-balance stability. Nothing in the entries points at a managed service, an AI/vector story, or a pricing change.

◆ Where it's heading

The arc is convergence on what users of established graph databases already expect: more of Cypher-like expressiveness, fewer sharp edges under concurrency. Successive releases stack pushdown optimizations (LIMIT into SHORTEST PATH, filters into property fetches) and shave latency in the Meta service, which suggests the pressure is coming from large-deployment operators rather than new-feature demand. Stability items — statement-count limits, plan-tree depth caps, leader-lease fixes — are the recurring theme.

◆ Prediction

Expect the next release to continue the same pattern: another batch of MATCH/GO planner optimizations and one or two query-language additions, rather than a new product surface. The entries give no signal about a v4 line or a hosted offering.

R
Rivet
DEVOPS
7.5

Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.

◆ Current state

Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.

◆ Where it's heading

Rivet keeps turning its S3-backed storage engine into features for agent workloads. Copy-on-write forking follows from the 3.0 storage design and gives agents a cheap way to branch a session, try something and discard it. The SDK and auth work of the past two months points to Rivet positioning actors as the runtime for agent backends.

◆ Prediction

Forking is likely to show up next in agentOS and the Pi integrations as a way to branch agent runs; the entries do not say when 3.0 leaves preview.
