Class TablespaceBuilder

  com.splout.db.hadoop.TablespaceBuilder

public class TablespaceBuilder
extends java.lang.Object

This class is the main entry point for generating Splout views. Here we will use a Builder for adding the mapping between a set of files in a FileSystem and the tables that we want to view in a Tablespace in Splout.

We need to use TableBuilder for obtaining Table beans. Then we can add Tables to the Tablespace.

We will obtain a TablespaceSpec bean after building it.
