⚡ Supercharge #ClickHouse on a budget! Project Antalya = 10x performance on 10x cheaper storage... and it's #opensource 🛠️ Repo’s live: hubs.la/Q03jJq5r0 Submit PRs, contribute, or drop a ⭐ (if you’re into that sort of thing).

#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: hubs.la/Q04gYsK60

"We're using #OpenTelemetry, so we have #observability." Most teams believe that until they see costs. 👀 Josh Lee is talking about what actually comes next at #SREday Munich tomorrow (2:30 PM). Expect OTel Arrow, Weaver, sampling & filtering strategies: hubs.la/Q04gYlfH0

"I'm yet to meet an engineer who tells me they love database migrations." 😅 In Ep 8 of #UnevenlyDistributed podcast, @ShivjiJha sat down with Josh Lee to talk about Iceberg, #AI agents, Postgres + #ClickHouse®, database optimizers, & more. Full episode: hubs.la/Q04gZ75M0

Everyone's running #AI experiments. Not everyone can tell you which ones are worth running in production. 😅 On May 20 (9 am PT), we're showing what stuck: MCP, agents, & schema design & query generation against #ClickHouse® on real datasets. Register: hubs.la/Q04ffkK10

#AI-powered homelabs are more than “run a model locally.” 😅 Henrik Rexed (@Dynatrace) and Josh Lee talk through the architecture, workflows, observability, and cloud vs. self-hosted tradeoffs behind the setup. Full #UnevenlyDistributed episode 👇🏻 hubs.la/Q04gcVcd0

#ClickHouse® migration gotcha: after rsyncing to multiple replicas, delete the server UUID file from each destination. 🛠️ Otherwise replicas sharing a #ZooKeeper ensemble will break each other's sessions & it's hard to debug. Full rsync #migration guide: hubs.la/Q04fZ0Qm0

Quick Q: when does #ClickHouse® ReplacingMergeTree actually deduplicate? 🤔 If your answer is "when data is inserted," then come to our May Office Hours. 📅 May 20 | 8 am PT ❗ Bring your edge cases 🙋🏼 Submit Qs to #officehours on Slack/register here: hubs.la/Q04fYVW00

Real-time analytics on cheap object storage, without tradeoff. 🔍 #AltinityAntalya 25.8.16.20002 adds GC support for #datalakes, icebergLocalCluster, EXPORT PARTITION for ReplicatedMergeTree, Hybrid table engine improvements, & observability updates. hubs.ly/Q04ffBD20

@fabiolauria92 GitOps continues to be a great mechanism for control. For a more detailed answer, come to the webinar.

Real-time analytics lose value when teams cannot act on the insights 📊 Most SMEs struggle with data accessibility rather than volume. The genuine bottleneck is not the tool itself but making analysis instant and accessible without requiring technical expertise. Your schema generation approach is intriguing. How are you managing governance in production environments?

The question every data team is asking: what #AI tools work for real-time analytics? 🤔 We'll demo it live on 5/20: MCP, agents, AI-generated schema design & queries running against real datasets in #ClickHouse®, & how to apply AI safely in prod. 💪🏻 hubs.la/Q04ffx910

You have 36 cores, 1TB of RAM, and fast NVMe disks. But your #ClickHouse® merges are still slow. Why? 🤔 The culprit is usually background_pool_size sitting at default while your hardware goes to waste. Get the full tuning guide with config snippet: hubs.la/Q04ffD2r0

There's a real difference between knowing how to use #ClickHouse® & knowing how it works. 🥸 Altinity Admin #Training covers MergeTree internals, replication, query optimization, troubleshooting & more across 4 live sessions. 🎟️ May is almost sold out: hubs.la/Q04d9d_D0

#ZooKeeper does the job. Until you need S3Queue, async replication, or half the features added in the last two years. 🤔 #ClickHouse® Keeper is the recommended replacement now. Get the full #migration guide, incl. upgrade caveats & Kubernetes setup: hubs.la/Q04dSgWh0 🔧

If you're giving AI agents access to #ClickHouse®, how are you handling auth? 🤔 #OAuth is now available in open source Altinity Antalya builds. Tomorrow at 8 AM PT, the team will walk you through configuration, real application usage, and the roadmap 🛣️: hubs.la/Q04d9fg00

Raw #OTel spans aren't actionable on their own. Error rate by service is, and in #ClickHouse® it's just one aggregation away. 👀 Try it against your own OTel traces data with our #demo (ships with logs): hubs.ly/Q04d9dmM0

#OAuth for #ClickHouse® is now available in open source Altinity Antalya builds. 💪🏻 On Apr. 28 (8 PT), learn how to configure it, use it in real applications, support AI agents securely, and what's next on the roadmap. 100% open source. ✅ Sign up: hubs.la/Q04d9byB0

Slow #Iceberg query starts? Repeated Parquet metadata overhead? 🐌 Altinity Antalya 26.1, a #ClickHouse® build for #datalake workloads, tackles both: async metadata prefetch & Parquet metadata cache + Google BigLake, PREWHERE for Iceberg, & more. 🚀 hubs.la/Q04cX2Lk0

$0.01/GB cross-zone, charged on both ingress & egress. 💰 At tens of TB/day ingested, a typical multi-AZ #ClickHouse® setup can hit several hundred dollars in network costs daily. Altinity CTO Alexander Zaitsev breaks down what drives it & how to fix it: hubs.la/Q04cKhYq0

Raw logs don't help you debug. 'Log volume over time' query does. 📉 It's the first patterns in our latest #ClickHouse® and #OpenTelemetry query guide, covering logs, metrics, traces, and resource attributes, with runnable queries for each. 📥 Download: hubs.la/Q04bVx9R0

Most teams don't have an #observability problem. They have a "can't turn data into answers" problem. 😅 So, we put together a query guide for working with OTel data in #ClickHouse® once it's ingested, covering logs, metrics, traces, & resource attributes: hubs.la/Q04bV2N_0
