A kdb Insights Database's configuration is composed of a schema, a stream, and multiple data tiers for real-time and historical data. In kdb Insights Enterprise, a database can be configured using the kdb Insights user interface, or using a configuration file called an assembly file.
At a minimum, an kdb Insights Database needs:
- A gateway for routing and an aggregator to aggregate responses.
- A set of labels to organize and route data queries.
- A schema configuration with one or more tables.
- A source stream to ingest data into the system.
- One or more data tiers for querying data.
Once the database has been configured, the database can be deployed.
In kdb Insights and kdb Insights Enterprise, configuration for a database can be submitted through an assembly file. When using kdb Insights Enterprise, databases can also be configured using the Insights user interface.
