RegexSerDe for Processing Apache Web Server Logs

SerDe Name


Library Name



The following example creates a table from CloudFront logs using the RegExSerDe from the Getting Started tutorial.


You can query data in regions other than the region where you run Athena. Standard inter-region data transfer rates for Amazon S3 apply in addition to standard Athena charges. To reduce data transfer charges, replace myregion in s3://athena-examples-myregion/path/to/data/ with the region identifier where you run Athena, for example, s3://athena-examples-us-east-1/path/to/data/.

CREATE EXTERNAL TABLE IF NOT EXISTS cloudfront_logs ( `Date` DATE, Time STRING, Location STRING, Bytes INT, RequestIP STRING, Method STRING, Host STRING, Uri STRING, Status INT, Referrer STRING, os STRING, Browser STRING, BrowserVersion STRING ) ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.RegexSerDe' WITH SERDEPROPERTIES ( "input.regex" = "^(?!#)([^ ]+)\\s+([^ ]+)\\s+([^ ]+)\\s+([^ ]+)\\s+([^ ]+)\\s+([^ ]+)\\s+([^ ]+)\\s+([^ ]+)\\s+([^ ]+)\\s+([^ ]+)\\s+[^\(]+[\(]([^\;]+).*\%20([^\/]+)[\/](.*)$" ) LOCATION 's3://athena-examples-myregion/cloudfront/plaintext/';
