ClickHouse
ClickHouse is a column-oriented analytical database built for very fast aggregation and scan-heavy queries on large event datasets. It is commonly used for API logs, product analytics, observability events, and customer activity history because it can process billions of rows with low latency when queries are written well. In support operations, ClickHouse is valuable because agents and automation can search recent request failures, workspace activity, and account-level patterns without pulling data into a separate warehouse first.
Why it matters for B2B support
Teams often use ClickHouse as the source of truth for investigating customer-reported API errors, degraded performance, or usage anomalies. The main operational concerns are schema design, partitioning, cardinality, retention, and query cost under concurrent load during incidents or support spikes.
How Altor helps
Portkey used ClickHouse as a critical investigation source, and Altor turns that kind of query work into a 45 min → 2 min support workflow instead of an engineering interrupt.
FAQ
Why do support teams care about ClickHouse?
Because many product and API events live there first. It is often the fastest way to confirm what the customer actually experienced.
Is ClickHouse a transactional database?
No. It is built for analytics and event-style workloads, not high-write transactional application state.
