I have the following Job class representing runs of a job. I have a list of start and end times in Job class because the same Job can be rerun.
public class Job {
private final List<Timestamp> jobStartTimes = new SortedList<>();
private final List<Timestamp> jobEndTimes = new SortedList<>();
private String jobName;
private String jobKey;
private String host;
....
....
}
I have this Map for querying jobs given jobkey.
public class JobMap {
/**
* Here value of 'String' key is jobKey
*/
private final Map<String, Job> jobCache;
}
I have also created the following hierarchy of hashmaps for storing (starttime, jobKey) and (endtime, jobkey) entries in Map so that I can retrieve job records faster. This is needed because my queries are timestamp based, for ex: return all jobs that ran between x and y timestamp.
public class YearCache<T> {
/**
* Here value of 'Integer' key is month number (0, 11)
*/
private final Map<Integer, MonthCache> monthCache;
}
public class MonthCache {
/**
* Here value of 'Integer' key is week number in a month(0, 4)
*/
private final Map<Integer, WeekCache> weekCache;
}
public class WeekCache {
/**
* Here value of 'Integer' key is day number in a week (0, 6)
*/
private final Map<Integer, DayCache> dayCache;
}
private class DayCache
{
/**
* Here value of 'Integer' key is hour value in a day (0, 23)
* T is of type String representing jobKey
*/
private final NavigableMap<Integer, NavigableMap<Timestamp, Set<T>>> hourCache;
}
I want to get rid of this Java hashmaps and move to Redis Cache. How can I model/architect this hierarchy in Redis Cache?
