- Paste the code from scripts/Zombie_MessageToS3.py script.

CREATE EXTERNAL TABLE IF NOT EXISTS default.zombie (
timestamp bigint,
name string,
message string
)
ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe'
WITH SERDEPROPERTIES (
'serialization.format' = ',',
'field.delim' = ','
) LOCATION 's3://BUCKET_NAME/data/'
TBLPROPERTIES ('has_encrypted_data'='false')
- Play with the interface and execute some standard S3 queries.

- Create a new environment variable. The key is USERS_TABLE_NAME, and the value is the name of your DynamoDB table where you store users.
- Increase the execution time of this function to 1 minute.
