@dengzhhu653, alterPartitions API supports batching
````
public List<Partition> alterPartitions(MTable table, List<String> partNames,
List<Partition> newParts, String
queryWriteIdList) throws MetaException {
List<Object[]> rows = Batchable.runBatched(batchSize, partNames, new
Batchable<String, Object[]>() {
}
````
so i don't get why we need to wrap 2 times?
````
Batchable.runBatched(partitionBatchSize, parts, new
Batchable<Partition, Void>() {
@Override
public List<Void> run(List<Partition> input) throws Exception {
msdb.alterPartitions(catalogName, newDbName, newTblName,
input.stream().map(Partition::getValues).collect(Collectors.toList()),
input, newt.getWriteId(), writeIdList);
return Collections.emptyList();
}
});
