I think the code here may be copied and pasted from the previous method, so it should be written like this
((MaxComputeCatalog) catalog)
.truncatePartition(
tablePath, new PartitionSpec(readonlyConfig.get(PARTITION_SPEC)));

Hi @W-dragan , after recreate schema, the old partition will be deleted too, so why we need truncate it not create it?

[W-dragan]

My understanding of 'recreate schema' is to delete a table or partition, and then recreate the table/partition. In the context of maxcompute, it is equivalent to overwrite=true.

Otherwise, the method you wrote in MaxCompute Catalog will not be called anywhere. Or is this method written in advance for future expansion?

public void truncateTable(TablePath tablePath, boolean ignoreIfNotExists)

it will be invoked in

seatunnel/seatunnel-api/src/main/java/org/apache/seatunnel/api/sink/DefaultSaveModeHandler.java

Line 217 in df14201

catalog.truncateTable(tablePath, true);

Understood, there is a deviation in my understanding. Thank you for your guidance
