All Implemented Interfaces:

```
public class QueuingRrdStrategy
extends Object
implements RrdStrategy<QueuingRrdStrategy.CreateOperation,String>, Runnable
```
Provides queuing implementation of RrdStrategy. In order to provide a more scalable collector. We created a queuing RrdStrategy that enabled the system to amortize the high cost of opening an round robin database across multiple updates. This RrdStrategy implementation enqueues the create and update operations on a per file basis and maintains a set of threads that process enqueued work file by file. If the I/O system can keep up with the collection threads while performing only a single update per file then eventually all the data is processed and the threads sleep until there is more work to do. If the I/O system is initially slower than than the collection threads then work will enqueue here and the write threads will get behind. As this happens each file will eventually have more than a single update enqueued and therefore the number of updates pushed thru the system will increase because more then one will be output per 'open' Eventually, the I/O system and the collection system will balance out. When this happens all data will be collected but will not be output to the rrd files until the next time the file is processed by the write threads. As another performance improving strategy. The queue distinguishes between files with significant vs insignificant updates. Files with only insignificant updates are put at the lowest priority and are only written when the highest priority updates have been written This implementation delegates all the actual writing to another RrdStrategy implementation. System properties effecting the operation: org.opennms.rrd.queuing.writethreads: (default 2) The number of rrd write threads that process the queue org.opennms.rrd.queuing.queueCreates: (default false) indicates whether rrd file creates should be queued or processed synchronously org.opennms.rrd.queuing.maxInsigUpdateSeconds: (default 0) the number of seconds over which all files with significant updates only should be promoted onto the significant less. This is to ensure they don't stay unprocessed forever. Zero means not promotion. org.opennms.rrd.queuing.modulus: (default 10000) the number of updates the get enqueued between statistics output org.opennms.rrd.queuing.category: (default "queued") the log routing prefix to place the statistics output in TODO: Promote files when ZeroUpdate operations can't be merged. This may be a collection miss which we want to push thru. It should also help with memory. TODO: Set an upper bound on enqueued operations TODO: Provide an event that will write data for a particular file... Say right before we try to graph it.

    Creates an RrdGraphDetails object representing the graph created from round robin data. It accepts an rrdtool graph command. The underlying implementation converts this command to a format appropriate for it .
    
    Specified by:
    
    createGraphReturnDetails in interface RrdStrategy<QueuingRrdStrategy.CreateOperation,String>
    
    Parameters:
    
    command - the command needed to create the graph
    
    workDir - the directory that all referenced files are relative to
    
    Returns:
    
    details for the graph including an InputStream, any PRINTed lines, and graph dimensions.
    
    Throws:
    
    IOException - if an IOError occurs
    
    RrdException - if an RRD error occurs
