DbExecutors (SpaceBase 2.1)

java.lang.Object
- co.paralleluniverse.db.api.DbExecutors

```
public class DbExecutors
extends Object
```
This is a factory class used to create executors (thread-pools) for Parallel Universe DB stores. The executors can, and should be shared by multiple stores.

public static ThreadPoolExecutor concurrent(String name,
                            int parallelism,
                            Thread.UncaughtExceptionHandler uncaughtExceptionHandler)
```
    Creates a thread pool to be used for running background cleanup tasks for DB stores in concurrent mode.
    
    Parameters:
    name - The thread pool’s name
    parallelism - parallelism The number of threads to use for background cleanup tasks.
    uncaughtExceptionHandler - The Thread.UncaughtExceptionHandler to use (pass null for the default handler).
    
    Returns:
    A newly constructed thread pool executor, which can (and should) be shared by multiple stores.
  - concurrent
```
