Logstash Grok Filters is now added by Amazon Athena to query data

Amazon Web Services has added support to Amazon Athena using Logstash Grok Filters to query data. Grok is beneficial for implementing patterns to examine unstructured data especially logs. It is convenient to use the Gork patterns instead of the regular expressions because each Grok pattern is basically a named regular expression. It will become easier to classify and re-use deserialization patterns. Logstash Grok filters have a set of advanced patterns. It also allows you to create custom patterns.
