The Glue Data Catalog is used for schema management. Redshift Spectrum and Athena both query data on S3 using virtual tables. With Athena you use whatever resources AWS allocates to your query and this can vary quite a bit in peak usage times. With Redshift Spectrum you have the freedom to increase the Redshift cluster size to boost compute power (in case of complex queries involving large datasets or needing faster response) which can be expensive. Athena is dependent on the combined resources AWS provides to compute query results while resources at the disposal of Redshift Spectrum depend on your Redshift cluster size. Let us consider AWS Athena vs Redshift Spectrum on the basis of different aspects: Provisioning of resourcesīoth Athena and Redshift Spectrum are serverless.

Automation means faster querying and faster insights. Tip: Did you know BryteFlow Ingest automatically enables Redshift external tables if configured? When BryteFlow creates a data lake on S3, Redshift or both in tandem, the initial sync and delta sync is merged automatically on S3 using a stateless EMR and file type and compression on S3 can be configured in the software. The analytical power of Redshift can be expanded to go beyond the local disks of the warehouse to query huge volumes of unstructured data on the Amazon S3 data lake without spending time on laborious loading or data transformation. The Redshift SQL Query Editor can be used to query exabytes of data in S3 as well as on Redshift cluster tables. Data Integration on Amazon S3 Amazon Redshift SpectrumĪmazon Redshift Spectrum is a feature of Amazon Redshift that allows you to query data in S3 without needing to load the data into your Redshift data warehouse. You may need to access data on S3 via an API or via Redshift Spectrum or other means. Hence, if you have several users needing to do interactive queries or using dashboards on data on Amazon S3, this may not be the solution for you. There are service limits imposed by AWS – you need to refer to these before deciding if this works for you. 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 is easy to use but requires some amount of data preparation

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. Read about BryteFlow for AWS ETL AWS AthenaĪWS Athena is a fast, serverless, interactive query service. Before we go into details, here is a quick rundown about both of them. Both are part of the AWS environment so it is quite natural to be a bit confused about which one you should use. Amazon Athena and Redshift Spectrum are both AWS services that can run queries on Amazon S3 data.
