For example, if 1 hour data was inserted at 15:00 for schedule id 123, then there would be a row in metrics_index with a partition key of {six_hour_metrics:15:00}. And that row would have a column with a value of the schedule id 123. This creates hot spots because the entire partition for a given bucket/time slice is stored on a single replic set. As the numnber of schedules having data for a given time slice grows, that row in the index becomes increasingly large. Adding more nodes to the cluster won't help. With this commit, a time slice index (i.e., row in metrics_index) is now broken down into multiple partitions (i.e., rows). A given time slice index will now be distributed across nodes. The partition key is now {bucket:schedule_offset:time_slice}. There will be at most 5,000 schedule ids per partition. Further testing is needed to determine if that size should be adjusted, be it smaller or larger. This change impacts the aggregation code. Previously 3 index queries were required, one for each of raw, 1 hour, and 6 hour data. Now multiple queries may be required for each respective bucket. While this change requires more reads, it is good in terms of scalability. As the overall load (in terms of) metrics increases, this change will help achive greater througput of aggregation particularly in a multi-node cluster. There is one key piece missing that I will add in a subsequent commit. The max and (optimally) min schedule ids need to be specified as arguments to the aggregation code in order to determine the range of index partitions. diff --git a/modules/enterprise/server/server-metrics/src/main/java/org/rhq/server/metrics/Aggregate1HourData.java b/modules/enterprise/server/server-metrics/src/main/java/org/rhq/server/metrics/Aggregate1HourData.java index bf50f26..a8ec709 100644 --- a/modules/enterprise/server/server-metrics/src/main/java/org/rhq/server/metrics/Aggregate1HourData.java +++ b/modules/enterprise/server/server-metrics/src/main/java/org/rhq/server/metrics/Aggregate1HourData.java @@ -52,6 +52,7 @@ public class Aggregate1HourData implements Runnable { Futures.addCallback(computeFutures, new FutureCallback<List<ResultSet>>() { @Override public void onSuccess(List<ResultSet> result) { + log.debug("Generated 1 hour data for schedule ids " + scheduleIds); log.debug("Finished aggregating 1 hour data for " + result.size() + " schedules in " + (System.currentTimeMillis() - start) + " ms"); state.getRemaining1HourData().addAndGet(-scheduleIds.size()); diff --git a/modules/enterprise/server/server-metrics/src/main/java/org/rhq/server/metrics/AggregateIndexEntriesHandler.java b/modules/enterprise/server/server-metrics/src/main/java/org/rhq/server/metrics/AggregateIndexEntriesHandler.java index 1eb9e53..9a1ddd7 100644 --- a/modules/enterprise/server/server-metrics/src/main/java/org/rhq/server/metrics/AggregateIndexEntriesHandler.java +++ b/modules/enterprise/server/server-metrics/src/main/java/org/rhq/server/metrics/AggregateIndexEntriesHandler.java @@ -6,9 +6,12 @@ import java.util.concurrent.atomic.AtomicInteger; import com.datastax.driver.core.ResultSet; import com.datastax.driver.core.Row; import com.google.common.util.concurrent.FutureCallback; +import com.google.common.util.concurrent.Futures; +import com.google.common.util.concurrent.RateLimiter; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; +import org.joda.time.DateTime; /** * @author John Sanda @@ -29,34 +32,67 @@ class AggregateIndexEntriesHandler implements FutureCallback<ResultSet> { private String dest; - public AggregateIndexEntriesHandler(Set<Integer> indexEntries, AtomicInteger remainingData, - SignalingCountDownLatch indexEntriesArrival, long startTime, String src, String dest) { + private String partitionKey; + + private RateLimiter writePermits; + + private MetricsDAO dao; + + private DateTime timeSlice; + + public AggregateIndexEntriesHandler(Set<Integer> indexEntries, AtomicInteger remainingData, String partitionKey, + MetricsDAO dao, RateLimiter writePermits, SignalingCountDownLatch indexEntriesArrival, long startTime, + String src, String dest, DateTime timeSice) { this.indexEntries = indexEntries; this.remainingData = remainingData; this.indexEntriesArrival = indexEntriesArrival; this.startTime = startTime; this.src = src; this.dest = dest; + this.writePermits = writePermits; + this.dao = dao; + this.partitionKey = partitionKey; + this.timeSlice = timeSice; } @Override public void onSuccess(ResultSet resultSet) { + int count = 0; for (Row row : resultSet) { indexEntries.add(row.getInt(1)); + count++; } - remainingData.set(indexEntries.size()); + remainingData.addAndGet(count); indexEntriesArrival.countDown(); if (log.isDebugEnabled()) { log.debug("Finished loading " + indexEntries.size() + " " + src + " index entries in " + (System.currentTimeMillis() - startTime) + " ms"); } + deleteIndexPartition(); } @Override public void onFailure(Throwable t) { - log.warn("Failed to retrieve " + src + " index entries.
