Since Machbase 5, STREAM is a newly supported real-time data processing function based on Continuous Query Language (CQL).
In other words, it is possible to extract the data satisfying a condition of incremental data inputted to the log table and to load it in real-time into another table.
If a conditional search is performed on all the data without using the stream function, the retrieval of the accumulated data is not only slow but also may be a heavy burden imposed on the system.
Stream can be used to retrieve conditions for specific log data entered in real time and respond quickly to events.
