Detached ≠ disposable. 😬 Before deleting #ClickHouse® detached parts, check the reason. Some are cleanup candidates, some are temporary, and some need investigation first. ⚠️ Full guide: kb.altinity.com/altinity-kb-us…
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 🗣️ hubs.ly/Q04yKnSG0
🌮 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. hubs.la/Q04yqYrW0
📣 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. 💡 Full docs: hubs.la/Q04ypVrf0
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 💡 Get the full breakdown: hubs.la/Q04xYzy60
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/sessions/obser…
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/merget…
🎡 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 🔗 hubs.la/Q04xY3Lt0
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
@theDanielJLewis @MongoDB @ClickHouseDB @Podgagement Awesome results! We're following along.
Your database and the workload querying it, side by side on the same rack: microsecond round trips, $0 egress, 20,000 IOPS included. Managed service for ClickHouse® by @AltinityDB, now on Nirvana. nirvanalabs.io/blog/nirvana-x… #ClickHouse #infrastructure #database
🇵🇱 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
@Slowdownbro67 Could you put the unstructured data in the resource attributes or do you mean more flexible than that? ClickHouse JSON columns are very well optimized.
Above NKS: @AltinityDB. The managed service for ClickHouse®: clusters, operator, console, monitoring, scaling, upgrades. Automatic backups, on-demand restore down to a single table. The full breakdown, all episodes 👇 nirvanalabs.io/blog/altinity-… #ClickHouse #BYOC
@pranshuraj211 Definitely odd. Probably an oversight more than a catch. The good news is you can use ADBC to get better performance AND built-in OTel instrumentation. If you want to learn more about ADBC, this may be helpful - altinity.com/unevenly-distr…
If older #ClickHouse® data is rarely queried, it may not need to stay on your fastest storage tier. 😎 #TTLs & tiered storage can keep recent data on fast block storage, move older data to S3, remove expired data automatically, & save storage cost by up to 30% (shown below). 👇🏻
A large export fails halfway through. So, restart from zero? 😬 While moving from #ClickHouse® ingestion to #ProjectAntalya, MindWise built o_rabbit so failed tasks retry independently & exports run in parallel. ⚡500GB export: 86 → 40 min on 4 workers: hubs.la/Q04wQWlJ0
A production incident is a bad time to learn how your #ClickHouse® cluster actually works. 🫠 Go deeper on storage, replication, resources, debugging, upgrades, monitoring, Keeper, & backups in 4 live Altinity #Administrator #Training sessions. 🚀 9/15: hubs.la/Q04x1Ny10
