TestBoundedTable |
addRows(java.lang.Object... args)
Add rows to the builder.
|
PCollection<Row> |
buildIOReader(PBegin begin)
create a
PCollection<Row> from source. |
POutput |
buildIOWriter(PCollection<Row> input)
create a
IO.write() instance to write to target. |
BeamTableStatistics |
getTableStatistics(PipelineOptions options)
Estimates the number of rows or the rate for unbounded Tables.
|
PCollection.IsBounded |
isBounded()
Whether this table is bounded (known to be finite) or unbounded (may or may not be finite).
|
static TestBoundedTable |
of(java.lang.Object... args)
Convenient way to build a mocked bounded table.
|
static TestBoundedTable |
of(Schema type)
Build a mocked bounded table with the specified type.
