To import partition data from S3 to Presto, you can follow these steps:

1. Ensure that you have an S3 bucket set up with the partitioned data that you want to import.
2. Make sure that your Presto server is set up and running properly.
3. Use the following SQL query to create an external table in Presto that points to your S3 bucket with partition data:

1
2
3
4
5
6
7
8
9

CREATE TABLE your_table_name (
    column1 data_type,
    column2 data_type,
    ...
)
WITH (
    format = 'PARQUET',
    external_location = 's3://your_bucket_name/your_data_folder/'
)

1. If your partitioned data is stored in subfolders within the S3 bucket, you can create partitioned tables in Presto using the following query:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10

CREATE TABLE your_partitioned_table (
    column1 data_type,
    column2 data_type,
    ...
)
WITH (
    format = 'PARQUET',
    partitioned_by = ARRAY['partition_column_name'],
    external_location = 's3://your_bucket_name/your_data_folder/'
)

1. Once your tables are set up, you can query them in Presto using standard SQL SELECT statements to retrieve the data from your S3 bucket.

By following these steps, you should be able to import partition data from S3 to Presto successfully.
