The data feed could be written directly to the RDB. More often, it is written to a kdb+ process called a tickerplant, which will:
- write all incoming records to a log file
- push all data to the RDB
- push all or subsets of the data to other processes
Other processes would subscribe to a tickerplant to receive new data, and each would specify what data should be sent: all or a selection.
