This is a super helpful script. Thank you! 🥳
One update (probably a change in AWS since you wrote the original): I had to also do a
table_input.pop()
on "VersionId". 😄
+1
and you might wanna add a batched add partitions à la
batch_size = 50 # NOTE must be lower than 100
while len(partitions) > 0:
partitions_batch = partitions[0:batch_size]
del partitions[0:batch_size]
partition_list = sorted([p.get("Values")[0] for p in partitions_batch])
print(f"+++\n\n adding partitions to {new_table_name}: {partition_list} \n\n+++")
client.batch_create_partition(
CatalogId=table_input["CatalogId"],
DatabaseName=database_name,
TableName=new_table_name,
PartitionInputList=partitions_batch,
)
