It emphasizes that these controls must remain reliable through crashes, timeouts, and retries, and presents Temporal Agent Harness as an execution-layer control point around an agent SDK. ### Source excerpt Auditing what an agent did is only half the job. Companies also have to control what agents may do, and make those limits hold when systems fail. ## Metastability as a failed conditional discharge of rely-guarantee composition DevFeed: [Metastability as a failed conditional discharge of rely-guarantee composition]() Original publisher: [Read original article]() Author: Murat (noreply@blogger.com) Published: 2026-09-03T01:03:24Z Content type: opinion Language: en Sources: [Metadata]() Topics: [systems](), [retry](), [Server](), [Latency]() Tags: [formal-methods](), [latency](), [metastability](), [retries](), [server](), [systems](), [tla]() ### AI overview This post models metastability in a retry storm using TLA+ and a retrier-server composition. It argues that a trigger can displace a system outside the rely-guarantee conditions of its components, after which duplicate retries add queue load and waste capacity. The model uses server capacity, fresh arrivals, retry timeouts, and latency thresholds to study the resulting failure behavior. ### Source excerpt Last week I wrote about modular verification of systems through open TLA+ specs and rely-guarantee discharge. In this post, I apply the same approach to study the metastability mechanics of a retry storm. Through this modeling I show that when the system is metastable, it is due to some trigger/shock that displaced the system outside the rely-guarantee discharge conditions of its components. The model I use the retrier-server example from the "Characterizing Metastable Faults and Failures" paper and model it in TLA+ as a composition of a retrier and a server component. The shared interface between the two components consist of the following variables: qf: fresh work queued at the server qd: duplicate (retry) work queued at the server done: the count of fresh requests the server completed this round, which the retrier reads and clears turn: a flag forcing alternation between the retrier and server steps The retrier has one private variable, p, which denotes the pending fresh requests: the requests sent and not yet acked. A retry is a duplicate of a request already counted in p, so sending one does not grow p. The server has no private state, and does not know about p. The constants in the specs parametrize the most important system characteristics: S=3 is the server capacity to process units per round AMax=2 is the max arrivals of fresh requests per round; retries arrive on top of this T=2 denotes retry timeout in rounds.

It explains how mixed workloads, overload, delayed signals, retries, and workload misclassification can create self-sustaining degraded states in cloud database systems. ### Source excerpt This week, I presented this paper at ICCCN'26. This is joint work with Aleksey Charapko (University of New Hampshire) and my MongoDB colleagues Matt Broadstone, Daniel Gomez Ferro, and Akshat Vig. The paper investigates how to build a metastability tolerant execution control system (ECS) for a database. Why? Modern databases are complex networked systems serving mixed workloads: short queries (that want an answer in milliseconds) sitting next to analytics jobs (that want the CPU for multiple seconds). The arrival rate of requests is effectively unbounded, but of course, the server's resources are not. And, unfortunately, elastic scaling does not save you here. Scaling takes minutes, whereas, overload takes seconds. Admission control tries to guard the front door (more on this later), but the component that mediates contention once requests reach the backend is the execution control system (ECS). Unlike a closed system OS scheduler, which strives for fairness and completeness by giving runtime for every thread, faced with an open environment the ECS can only afford to protect short latency-sensitive queries and shed the excess, pushing the burden of waiting back across the network to the clients. This doesn't mean that long tasks are starved, as they can retry until capacity permits execution. However, shedding load across a network is risky business. Clients do not see the server slow down, instead they time out and retry aggressively. Moreover, workloads are also unpredictable. A query that looks short may hang on a lock or blow up into a scan. The combination of delayed signals, retries, and misclassification makes the cloud databases a fertile ground for failures. The specific failure we worry about here is metastability: the system gets pushed into a degraded state, and the degraded state sustains itself even after the original trigger is removed. The mechanisms you build for resilience (the retries and the queues) turn into positive feedback loops after a trigg ## How to build deep research agents using Temporal and Braintrust DevFeed: [How to build deep research agents using Temporal and Braintrust]() Original publisher: [Read original article]() Author: Martin Bergman Published: 2026-06-03T00:00:00Z Content type: tutorial Language: en Sources: [Temporal Blog]() Topics: [Multi Agent Systems](), [observability](), [Pydantic](), [parallel](), [retry](), [Large Language Model]() Tags: [agents](), [build](), [how-to](), [multi-agent](), [observability](), [parallel](), [research](), [retry](), [tracing]() ### AI overview This tutorial explains a multi-agent deep research pipeline built with Temporal and Braintrust.

It listens for DNS NOTIFY messages so it can respond to changes promptly. It also uses each zone's SOA refresh and retry parameters to poll for updates if nsnotifyd does not receive NOTIFY messages more frequently. It comes with a client program nsnotify for sending notify messages. This nsnotifyd-2.4 release includes a new feature and some bug fixes: The new -S option tells nsnotifyd to send all SOA queries to a specific server. Previously, in response to a NOTIFY message, it would send a SOA query back to the source of the NOTIFY, as specified by RFC 1996. (Typically, a NOTIFY will only be accepted from a known authoritative server for the zone. The target of the NOTIFY responds with a SOA refresh query and zone transfer. But it should avoid trying to refresh from one of the other authoritative servers which might not have received the latest version of the zone.) Mark Felder encountered a situation where it would have been more convenient to fix the address that nsnotifyd sends SOA queries to, because the source of the NOTIFY messages wasn't responding on that address. Since nsnotifyd is intended to work as glue between disparate parts of a system, it makes sense for it to work around awkward interoperability problems. The nsnotify client program was broken and unable to create NOTIFY messages. D'oh! I have adjusted the release process so that it works better with git archive and web front-ends that offer tarball downloads. ## The hero's journey to AI durability with Temporal DevFeed: [The hero's journey to AI durability with Temporal]() Original publisher: [Read original article]() Author: Tim Imkin Published: 2026-01-14T00:00:00Z Content type: tutorial Language: en Sources: [Temporal Blog]() Topics: [Artificial Intelligence](), [Large Language Model](), [reliability](), [Development](), [retry](), [Networks](), [Databases](), [Filesystems]() Tags: [ai](), [apis](), [databases](), [durability](), [how-to](), [networks](), [reliability](), [retry](), [temporal](), [workflows]() ### AI overview The article explains how Temporal Workflows and Activities can make multi-step AI features durable when workers restart or networks, APIs, databases, file systems, and user actions fail.
