All the com.splout.db.common.SploutConfiguration properties related to the DNode.
public class DNodeProperties {

The data folder that will be used for storing deployed SQL data stores.
	public final static String DATA_FOLDER = "dnode.data.folder";
This DNode's host name
	public final static String HOST = "dnode.host";
This DNode's port
	public final static String PORT = "dnode.port";
How many threads will be allocated for serving requests in Thrift's ThreadPoolServer
	public final static String SERVING_THREADS = "dnode.serving.threads";
Whether this DNode should find the next available port in case "dnode.port" is busy or fail otherwise.
	public final static String PORT_AUTOINCREMENT = "dnode.port.autoincrement";
The amount of seconds that the DNode will cache SQL connection pools. After that time, it will close them. Remember that the DNode may receive requests for different versions in the middle of a deployment, so that's why we want to expire connection pools after some time (to not cache connection pools that will not be used anymore).
	public final static String EH_CACHE_SECONDS = "dnode.pool.cache.seconds";
The amount of seconds that the DNode will wait before canceling a too-long deployment.
	public final static String DEPLOY_TIMEOUT_SECONDS = "dnode.deploy.timeout.seconds";
A hard limit on the number of results per each SQL query that this DNode may send back to QNodes.
	public final static String MAX_RESULTS_PER_QUERY = "dnode.max.results.per.query";
If set, this DNode will listen for test commands. This property is used to activate responsiveness to some commands that are useful for integration testing: making a DNode shutdown, etc.
	public final static String HANDLE_TEST_COMMANDS = "dnode.handle.test.commands";
Number of SQL connection pools that will be cached. There will be one SQL connection pool for each tablespace, version and partition that this DNode serves. So this number must not be smaller than the different numbers of tablespace + version + partitions.
	public final static String EH_CACHE_N_ELEMENTS = "dnode.pool.cache.n.elements";
In milliseconds, queries that are slower will be logged with a WARNING.
	public final static String SLOW_QUERY_ABSOLUTE_LIMIT = "dnode.slow.query.abs.limit";
Queries that run for more than this time will be interrupted.
	public final static String MAX_QUERY_TIME = "dnode.max.query.time";
