There are certain restrictions imposed by AWS on user access to Athena, which you should be aware of. Build an S3 Data Lake in Minutes Things to know regarding user access on Amazon Athena Automated data preparation means faster querying and insights. It also interfaces automatically with Glue Data Catalog and AWS Lake Formation. This means data can be automatically viewed in Athena with no extra effort. The initial sync and delta sync is merged continuously and automatically on S3 using a stateless EMR and file type and compression on S3 can be configured in the software. Tip: Did you know BryteFlow Ingest automatically creates tables in Athena as it loads to S3? It gets data from the sources – real-time using log Change Data Capture, merges the deltas and prepares data that is ready to use. When you are ingesting sources near real-time to S3 from structured databases using Change Data Capture methodology, you do need to merge the real-time changes with the previous data sync – so there is some data preparation involved. Anyone with decent SQL skills can analyze big datasets. Query results are delivered extremely fast and you can avoid the nuisance of complex ETL jobs to make your data ready for analytics. To use Athena, simply point to your data on S3, define schema and start querying using standard SQL.

Athena supports various S3 file formats including CSV, JSON, PARQUET, ORC and AVRO and allows for partitioning of data which is key to smooth large volume data queries.ĭownload our eBook: How to get siloed data to AWS Athena in just a few clicks. There is no infrastructure to manage and you only pay for the queries you run – pretty cost-effective if you ask us. You do not need to load data into Athena, you can use Athena to query your data on S3. It is simple to use since you can analyze data using standard SQL.
