In the end, which solutions did you choose from? ClickHouse, ELK, and what was the third one?

When choosing a solution for data storage and analysis, three main options were considered:

1. ClickHouse — a columnar DBMS, ideal for real-time analytics and large volumes of data.
2. ELK Stack (Elasticsearch, Logstash, Kibana) — a powerful stack for collecting, indexing, and visualizing logs and metrics.
3. TimescaleDB — an extension of PostgreSQL for working with time series data, suitable for monitoring and metrics.

The choice depended on specific requirements: if high-speed analytics on large data was needed — ClickHouse; for flexible log handling and visualization — ELK; for time series and complex queries — TimescaleDB.
