Example 1 with RebalanceFactory

use of org.apache.geode.cache.control.RebalanceFactory in project geode by apache.

the class RegionHelper method rebalanceRegion.

public static RebalanceResults rebalanceRegion(Region region) throws CancellationException, InterruptedException {
    // FilterByName only looks at name and not full path
    String regionName = region.getName();
    if (!PartitionRegionHelper.isPartitionedRegion(region)) {
        StringBuilder builder = new StringBuilder();
        builder.append("Region ").append(regionName).append(" is not partitioned. Instead, it is ").append(region.getAttributes().getDataPolicy()).append(". It can't be rebalanced.");
        throw new IllegalArgumentException(builder.toString());
    }
    // Rebalance the region
    ResourceManager resourceManager = region.getCache().getResourceManager();
    RebalanceFactory rebalanceFactory = resourceManager.createRebalanceFactory();
    Set<String> regionsToRebalance = new HashSet<String>();
    regionsToRebalance.add(regionName);
    rebalanceFactory.includeRegions(regionsToRebalance);
    RebalanceOperation rebalanceOperation = rebalanceFactory.start();
    // Return the results
    return rebalanceOperation.getResults();
}

Example 3 with RebalanceFactory

use of org.apache.geode.cache.control.RebalanceFactory in project geode by apache.

the class MyGatewayEventSubstitutionFilter method doRebalance.
