I try to edit SparkTable implements SupportsPartitionManagement
`@Override`
public StructType partitionSchema() {
return (StructType)
SparkSchemaUtil.convert(icebergTable.spec().partitionType());
}
@Override
public void createPartition(InternalRow ident, Map<String, String>
properties)
throws PartitionAlreadyExistsException,
UnsupportedOperationException {
if(partitionExists(ident)){
throw new PartitionAlreadyExistsException(name(), ident, schema());
}
else{
icebergTable.updateSpec()
.addField((Term) ident.toSeq(partitionSchema()))
.commit();
}
}
@Override
public boolean dropPartition(InternalRow ident) {
try{
if (partitionExists(ident)){
icebergTable.updateSpec()
.removeField(ident.toSeq(partitionSchema()).mkString())//
term
.commit();
return true;
}
}catch (IllegalArgumentException e) {
LOG.info("no partition exists for the identifier");
}
return false;
}
@Override
public void replacePartitionMetadata(InternalRow ident, Map<String,
String> properties) throws UnsupportedOperationException {
throw new UnsupportedOperationException("Iceberg partitions do not
support metadata");
}
@Override
public Map<String, String> loadPartitionMetadata(InternalRow ident) throws
UnsupportedOperationException {
throw new UnsupportedOperationException("Iceberg partitions do not
support metadata");
}
@Override
public InternalRow[] listPartitionIdentifiers(String[] names, InternalRow
ident) {
return new InternalRow[0];
}
