⚠️ Every upgrade carries regression risk.

Upstream #ClickHouse® ships monthly, but only 3 latest releases are supported & LTS lasts a year.

#AltinityStableBuilds go through build, test & security validation, with up to 3 years of support. Try the #demo:

🧱 Fast storage gets expensive.

Object storage is cheaper, but the query path gets more complicated.

#ProjectAntalya's Hybrid tables query #ClickHouse® MergeTree & #Iceberg with one SQL statement, tested here on NYC taxi & US flight data. Try the demo: https://t.co/Vm8CszxOr6

Your IdP already controls access to everything else. Why should #ClickHouse® be the odd one out?

#AltinityAntalya builds now support #OAuth token-based auth w/ any OIDC provider. Short-lived tokens, IdP role mapping, no shared passwords. Now GA in 26.3: https://t.co/oQRyIoSSiN

#ClickHouse® time filters can look right and still return the wrong rows. ⏰

DateTime literals, column/session/server timezones, and DST gaps can change what your filter actually means. No error, just surprising results.

Heads up if you're launching a replica cluster in #AltinityCloud for #ClickHouse®: it's a true replica, not a one-time copy. ⚠️

Changes to the #replica sync back to the source. The docs flag it as advanced-users-only for a reason.

Every #ClickHouse® cluster architecture question has the same answer: "it depends." 😅

Join the #OfficeHours on June 23 to hear what it depends on as our engineers discuss Distributed & #Cluster Architecture.

🌉 Hey SF! We're coming tomorrow to de-influence you about AI & production data. Expect talks on:
- what happens when an AI agent deletes a production table
- instrumenting & evaluating #AI agents before they break things & more

If a Keeper node ever went quiet after a config change, check out the Altinity #Kubernetes Operator for #ClickHouse® 0.26.2 - Keeper offline, race condition, & namespace handling fixes, CVE-2026-24051 patched, and faster multi-node CHI/CHK deletion. 🛡️

#AI in production is already breaking things. 3 #meetups this June are tackling the messiest parts. Talks on agent safety, AI #observability, agent telemetry analytics, and product insights.

SEATTLE: https://t.co/kgzzZ9YhH1
LA: https://t.co/gDRBvMc4qT

🚨 If an #AI agent queries #ClickHouse® on behalf of a user, the access model matters.

#AltinityAntalya 26.3 adds OAuth authorization support in Antalya builds, plus more work for Iceberg/S3 and hybrid table use cases.

Josh Lee is pulling double duty at #KCDNewYork tomorrow: lightning talk at 8:25 AM on OTel vendor neutrality in practice, then a panel at 11:20 AM on #telemetry that actually matters with Carol Valencia (KrolCloud) & Diana Todea (VictoriaMetrics).

Most #observability problems aren't tool problems. They're instrumentation problems. 🔍

Josh Lee is breaking it down tomorrow at #SREday NY: #OTel Arrow, sampling, filtering, schema management with Weaver, & what to actually instrument.

A customer's #AI agent deleted production #ClickHouse® tables the morning of this webinar. 😬

We demoed 3 tools to prevent exactly that: #MCP read-only mode, DBA Skills, & OAuth guardrails.

➕ See how #Claude builds a Grafana dashboard from a query.

What tools does a team of #ClickHouse® experts have in their AI toolkit? 🧰

Tomorrow, the Altinity team opens the attic: MCP, skills, spec-based development, code reviews, security holes, & what #AI means for real-time analytics.

🛠️ AI demos are easy. Building #AI systems that work in prod is where it gets interesting.

And that's exactly what practitioners will explore at OSA Community #meetups this June:

CVE severity scores weren't designed to answer "should I wake someone up right now?" 🛡️

They're calculated against a generic baseline with no deployment context. Mikhail Filimonov, Principal Engineer, shows how to actually triage CVEs for #ClickHouse®: https://t.co/VEsxpKRyUh

#ClickHouse® deployments generate thousands of alerts a day. No team can reliably act on all of them. 😮‍💨

But #AI changes that. Catch @dbcicero's demo at #PerconaLive Bay Area on 5/27 (11:20 AM): AI-assisted alert analysis, root cause automation + more: https://t.co/aS7DZwZ1NI

#FIPS 140-2 & FIPS 140-3 look the same from the outside. The #encryption library underneath is a different story. 🔒

Altinity's #ClickHouse® v25.3.8 FIPS build replaces OpenSSL w/ AWS-LC (FIPS 140-3 certified, better encrypt/decrypt perf). ARM supported: https://t.co/7kbFdsrPD9

#AI workloads don't behave like traditional apps. So why are most data systems still designed like they do? 🤔

Josh Lee will open #LLMday London as a keynote on May 28, covering how to support AI workloads that demand speed, scale, & operational clarity: https://t.co/xp486qOcU6
