If your data has been successfully stored in Parquet format, you would then create a table definition that references those files.

Here is an example statement that uses Parquet files:

CREATE EXTERNAL TABLE IF NOT EXISTS elb_logs_pq (
  request_timestamp string,
  elb_name string,
  request_ip string,
  request_port int,
  ...
  ssl_protocol string )
PARTITIONED BY(year int, month int, day int) 
STORED AS PARQUET
LOCATION 's3://athena-examples/elb/parquet/'
tblproperties ("parquet.compress"="SNAPPY");

This example was taken from the AWS blog post Analyzing Data in S3 using Amazon Athena that does an excellent job of explaining the benefits of using compressed and partitioned data in Amazon Athena.
