~10x cold read speedup vs AWS gp3. Database and workload on the same rack. $0 internal egress. ~70M rows/sec sustained from disk. That's #ClickHouse® on @nirvanalabsai, the new BYOC option for #AltinityCloud. Benchmarks & repos are public. 💪🏽

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.

🎉 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.

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.

🌮 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.

📣 Raw EXPLAIN text can be a lot to parse.
The #AltinitySQLBrowser turns #ClickHouse® EXPLAIN PIPELINE output into an interactive processor graph, so parallelism and Resize points are easier to spot. Pan, zoom, or open it fullscreen.

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…
🎡 Hey Londoners, we'll be at the Data Engineering London #meetup tomorrow for an evening on Storage + #AI.
Expect deep dives on Hot SSDs to #lakehouses, data movement, metadata performance, and more.
📍 London Art Bar | 6 pm
🍻 Food + drinks on us

Your analytical database is columnar & your dataframe library is too. But the path between them often isn't. That can mean extra copies & transposes to move query results. 😓
See how #ApacheArrow & #ADBC can eliminate that in this Unevenly Distributed ep: hubs.la/Q04xRPlG0

Your database and the workload querying it, side by side on the same rack: microsecond round trips, $0 egress, 20,000 IOPS included.

🇵🇱 Warsaw - thank you for making it an evening to remember.
Huge thanks to #OSACommunity for bringing everyone together, @dbcicero & other speakers for sharing the stage, & Josh Lee for hosting. Shoutout to everyone from the open source community who made the meetup so special.
Disk, memory, CPU, network. When #ClickHouse® has a problem, which one do you check first? 🤔
Our Sept. admin #training gets into ClickHouse internals so you can diagnose issues instead of guessing.
4 live sessions starting tomorrow (limited seats left): hubs.la/Q04x0mqb0
