Field Detail

minorType

public TypeProtos.MinorType minorType

Column type given as a Drill minor type (that is, a type without the extra information such as cardinality, width, etc.

name

public String name

mode

public TypeProtos.DataMode mode

width

public Integer width

precision

public Integer precision

scale

public Integer scale

generator

public String generator

The scan can request to use a specific data generator class. The name of that class appears here. The name can be a simple class name, if that class resides in this Java package. Or, it can be a fully qualified name of a class that resides elsewhere. If null, the default generator for the data type is used.

repeat

public Integer repeat

Some tests want to create a very wide row with many columns. This field eases that task: specify a value other than 1 and the data source will generate that many copies of the column, each with separately generated random values. For example, to create 20 copies of field, "foo", set repeat to 20 and the actual generated batches will contain fields foo1, foo2, ... foo20.

properties

public Map<String,Object> properties
