Have you worked with ClickHouse, Cassandra, Elasticsearch?

Yes, I have worked with each of these tools:

• ClickHouse — used for analytical queries with large volumes of data due to its high speed and columnar storage.
• Cassandra — employed for storing distributed data with high availability and scalability, especially in systems with a large number of records and the need for horizontal scaling.
• Elasticsearch — used for full-text search and analytics on logs and other unstructured data, thanks to its powerful indexing capabilities and fast search.

Each of these technologies is suitable for specific tasks related to storing and processing big data.
