Description
SCHEMA
--------
message Person {
int32 foo = 1;
oneof optional_bar {
int32 bar_int = 200;
int32 bar_int2 = 201;
string bar_string = 300;
}
}
CODE
--------
I set values for foo and bar_string
for (int i = 0; i < 3; i += 1) {
com.etsy.grpcparquet.Person message = Person.newBuilder()
.setFoo(i)
.setBarString("hello world")
.build();
message.writeDelimitedTo(out);
}
And then I write the protobuf file out to parquet.
RESULT
-----------
$ parquet-tools show example.parquet +-------+-----------+------------+--------------+ | foo | bar_int | bar_int2 | bar_string | |-------+-----------+------------+--------------| | 0 | 0 | 0 | hello world | | 1 | 0 | 0 | hello world | | 2 | 0 | 0 | hello world | +-------+-----------+------------+--------------+
bar_int and bar_int2 should be EMPTY for all three rows since only bar_string is set in the oneof. 0 is the default value for int, but it should not be stored.
