AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Description: >
Stack that deploys a bucket which you can use as a target for your
Amazon CloudFront access logs (use the prefix 'new/'). An event
notification is configured so that new objects created will fire an
AWS Lambda function that moves the objects to prefixes (under
'partitioned-gz/') that adhere to the Apache Hive partitioning format.
This way the data is easier to consume for big data tools (as Amazon
Athena and AWS Glue).
Parameters:
ResourcePrefix:
Type: String
Default: 'myapp'
AllowedPattern: '[a-z0-9]+'
MinLength: 1
MaxLength: 20
Description: >
Prefix that is used for the created resources (20 chars, a-z and 0-9 only)
NewKeyPrefix:
Type: String
Default: 'new/'
AllowedPattern: '[A-Za-z0-9\-]+/'
Description: >
Prefix of new access log files that are written by Amazon CloudFront.
Including the trailing slash.
GzKeyPrefix:
Type: String
Default: 'partitioned-gz/'
AllowedPattern: '[A-Za-z0-9\-]+/'
Description: >
Prefix of gzip'ed access log files that are moved to the Apache Hive
like style. Including the trailing slash.
ParquetKeyPrefix:
Type: String
Default: 'partitioned-parquet/'
AllowedPattern: '[A-Za-z0-9\-]+/'
Description: >
Prefix of parquet files that are created in Apache Hive
like style by the CTAS query. Including the trailing slash.
