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).
Read the blog post
https://aws.amazon.com/blogs/big-data/analyze-your-amazon-cloudfront-access-logs-at-scale/
for further details about this sample asset (uksb-1tupboc62).
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.
