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.
Databases are configured using an assembly object to correlate a database, a schema, and a stream to a deployment.
