Altinity Backup for ClickHouse® v2.6.42 is out.
Smarter restores with --skip-empty-tables for restore / restore_remote
Faster backup retention cleanup with batched key deletions
More robust S3 multipart, now respecting S3_MAX_PARTS_COUNT for S3-compatible backends
Notes: github.com/Altinity/cli...
ClickHouse® is fast. #AltinityCloud makes it feel like an API. 🔐
In a new post, we use a NYC taxi sample dataset to show how API Endpoints turn ClickHouse queries into JSON endpoints your app can call directly, so you don’t have to wire drivers & SQL into every service.

📣 Here's quick look at the different sharding and replication patterns in ClickHouse®:
1. Sharded and replicated (the most common)
2. All replicated
3. All sharded
👾 Both projects are open source and available on GitHub! Clone ‘em, star ‘em, break ‘em, and tell us what you’d fix.
Running ClickHouse® on Iceberg doesn’t have to be hard. Here are two tools to make it easier:
⚡ github.com/Altinity/ant...: Stateless, auto-scaling compute swarms. Spin up queries on Iceberg + Parquet
❄️ github.com/Altinity/ice: A simple toolkit to build Apache Iceberg REST catalogs in a few lines
Tiny inserts in ClickHouse® are slow and expensive. And in many pipelines, you can’t just batch client-side.
That’s where async inserts help: #ClickHouse batches rows on the server, leading to better loading performance. No pipeline changes needed!
