Class ParameterRecorder

java.lang.Object

com.google.common.util.concurrent.AbstractService

org.yamcs.archive.ParameterRecorder

All Implemented Interfaces:

com.google.common.util.concurrent.Service

public class ParameterRecorder
extends com.google.common.util.concurrent.AbstractService

ParameterRecorder Records (processed) Parameters The base table definition is ParameterDataLinkInitialiser This records parameters as tuples - good for realtime recording but not very efficient for retrieval of a few parameters over long time periods. The org.yamcs.parameterarchive records parameters in a columnar fashion - not good for realtime but much more efficient for retrieval especially retrieval of few parameters over long time periods.
