thank you for the shoutout! We'd be happy to help.
An #AI agent dropped a production #ClickHouse® table. 🫠 It even changed a safety setting to do it.
Nowadays, "don't touch production" isn't a security policy.
We explore how scoped RBAC, read-only MCP access & agent sandboxing are the right guardrails: hubs.la/Q04Bwtlf0
⚡ Copy a statement. Run it. Copy the next one. Keep going.
Or paste the whole script into the #AltinitySQLBrowser. It runs each #ClickHouse® statement in order, with its own result & timing, and stops on the first error.

🤔 What’s working? What broke? And what does the data stack look like when AI is part of it? Get the answers and leave with a playbook.
🎉 We're proud to be the Platinum Sponsor of #OSACON 2026. 🎉
Join us & other data & #AI practitioners & builders on Nov. 2 (SF/online) as we deconstruct AI workloads, agents operating analytics platforms, #datalakes, open-source architectures, & more.

Do you have a calendar? We're unable to send a DM (to verified accounts). :/
We're huge fans of both (Langfuse and ClickHouse®)! If you go the self-hosted route, please feel free to drop into our community Slack with any questions - altinity.com/slack

Hey Laurentiu - this is amazing! Would you be interested in sharing your story with us? (No sales - we really think what you achieved is great and want to learn more.)
Data is growing, but query load isn't?
CAS (experimental in #AltinityAntalya 26.6) lets #ClickHouse® #MergeTree tables use shared object storage.
📦 Storage scales independently of compute
🔗 Nodes share identical files
Cold-tier use for now. See how 👇

🔥 Hot data in #ClickHouse® MergeTree. Colder data in #Iceberg. One query across both.
On Oct. 27, Robert Hodges & Alexander Zaitsev will show how #AntalyaBuilds combines Hybrid tables, swarms, OAuth, CAS for shared MergeTree storage, & MCP.

↹ Changed a #ClickHouse® table & now need to figure out what else depended on it? #AltinitySQLBrowser maps the connections for you. Drag a database/table from the schema tree into the results pane & it builds a data-flow graph showing #materializedviews.

Detached ≠ disposable. 😬
Before deleting #ClickHouse® detached parts, check the reason. Some are cleanup candidates, some are temporary, and some need investigation first. ⚠️

Will #AI create an extinction event for open-source DB projects? 💀
Altinity CEO @dbcicero will explore what AI is changing at the database layer, incl. security, MCP connectivity, & what comes next for open source at #OSACON 2026.
📅 Nov 2 | 10 am PT

🌮 Tomorrow evening: tacos + #observability, MCPs, #AI, OTel, & ClickHouse® at Grafana & Friends.
We’ll join talks & conversations around some current engineering problems: safer AI data access, MCP + k6, OTel on #K8s, & stateless #ClickHouse® ingestion.

Slow #ClickHouse® query? Start with the built-in tools. 💪🏽
▪ query_log: resources + runtime
▪ processors_profile_log: time per stage
▪ query_metric_log: live stats
▪ EXPLAIN + the chdig CLI

Scaling #ClickHouse® storage without scaling compute? Meet CAS. 💥
Content-Addressed Storage (#CAS) adds shared object storage to existing MergeTree model, so storage can scale independently without replacing #MergeTree with a new engine.
CAS explained: hubs.la/Q04y7dTR0

We're excited to have Joshua Lee, Developer Advocate for @AltinityDB, presenting "Observability is Broken and Open-Source (will be) the Solution" at #AllThingsOpen! 2026.allthingsopen.org/sessi…
0.65s vs. 1.42s on ~126M rows. Same #ClickHouse® table, same filter. The only change was the query’s ORDER BY. ⚡
If a query is sorting more than expected, check whether its ORDER BY matches the table’s: kb.altinity.com/engines/merg…
