amazon web services - Athena Write Performance to AWS S3 -


so i'm executing query in aws athena , writing results s3. seems taking long time (way long in fact) file available when tell query execute lambda script. i'm scanning 70mb of data, , file returned 12mb. execute lambda script so: 

athena_client = boto3.client('athena') athena_client.start_query_execution(     querystring=query_string,     resultconfiguration={         'outputlocation': 'location_on_s3',         'encryptionconfiguration': 'sse_s3',     } )

if run query directly in athena takes 2.97 seconds run. looks file available after 2 minutes if run query lambda script.

does know write performance of aws athena aws s3? know if normal. docs don't state how write occurs.
