How did data get into your analytics system from other services?

Data into the analytical system from other services typically came through the following approaches:

• ETL processes: regular extraction of data from service databases, transformation, and loading into an analytics repository (e.g., Data Warehouse).

• Stream integration: using messaging systems (Kafka, RabbitMQ) to transmit events and data in real-time.

• API integration: services provide REST or gRPC APIs, from which the analytical system periodically requests the necessary data.

• Logging and log parsing: collecting logs from services and processing them to extract analytical information.

For example, in one project, user action data was published to Kafka by the service, from which the analytical system consumed events and aggregated them for real-time reports.
