What is Dragonfly?

Dragonfly fixes dropped writes during slot migration and rebalances slot-based sharding.

Dragonfly is maintaining two incremental lines, 1.40 and 2.0, with small, targeted releases. The 2.0 line fixed a slot-migration bug that silently dropped journal writes into empty buckets and changed experimental slot-based sharding to Fibonacci hashing so keys spread evenly. The 1.40 line received BLMOVE and Sidekiq queue-placement optimizations.

What is incident.io?

incident.io's agent now runs your team's own tools, with a human approval before any change.

Investigations, the agent that posts a root-cause hypothesis when an incident opens, is the center of incident.io; it went GA and then doubled its speed in September. In October the company pushed its agent skills out into coding harnesses, then opened Nexus to customers' own tools and know-how. The 10-28 release restates that extension model and adds an explicit step: any change the agent proposes waits for a human approval before it runs.

Dragonfly vs incident.io: editorial side-by-side

D
Dragonfly
INFRA · APIS
5.0

Dragonfly fixes dropped writes during slot migration and rebalances slot-based sharding.

◆ Current state

Dragonfly is maintaining two incremental lines, 1.40 and 2.0, with small, targeted releases. The 2.0 line fixed a slot-migration bug that silently dropped journal writes into empty buckets and changed experimental slot-based sharding to Fibonacci hashing so keys spread evenly. The 1.40 line received BLMOVE and Sidekiq queue-placement optimizations.

◆ Where it's heading

Most of the work is in cluster mode: migrations, slot placement and topology replies. That suggests the 2.x line is being hardened for multi-node deployments, while 1.40 still gets backports and small performance fixes.

◆ Prediction

The slot-based sharding flag looks likely to stay experimental for a while, with more balancing and migration fixes before it becomes a default.

7.5

incident.io's agent now runs your team's own tools, with a human approval before any change.

◆ Current state

Investigations, the agent that posts a root-cause hypothesis when an incident opens, is the center of incident.io; it went GA and then doubled its speed in September. In October the company pushed its agent skills out into coding harnesses, then opened Nexus to customers' own tools and know-how. The 10-28 release restates that extension model and adds an explicit step: any change the agent proposes waits for a human approval before it runs.

◆ Where it's heading

incident.io is turning its agent into a two-way integration point that can act, not just diagnose. Skills go out to developers' agents, internal tools and team context come in, and the approval gate is what makes write access acceptable during an incident. Dashboards, ticket sync and alert routing keep incident.io as the record the agent reads from and writes to.

◆ Prediction

Expect worked examples for common connected systems such as deploy or feature-flag tools, and Investigations that propose concrete remediation steps for approval. The entries do not say how extensions are built or priced.
