org.linuxforhealth.fhir.persistence.jdbc.dao.impl.ReferencesSequenceDAO

public class ReferencesSequenceDAO
extends java.lang.Object

Handles the acquisition of sequence values from REFERENCES_SEQUENCE. For optimization, the sequence increments by a larger value, allowing us to allocate numbers without having to ask the database each time. This helps, because we assume each persistence operation will need to use a handful of values, and anything we can do to avoid database round-trips is a good thing
