12/10/2023 0 Comments Benefits of amazon redshift![]() Limited support but higher coverage with Spectrum Performance depends on the query hit over S3 and partitionĭata depends upon the values present in S3 files Partitioning is quite handy while working in a Big Data environment Redshift Vs Athena – Feature Comparison Table Feature Type Along with this Athena also supports the Partitioning of data. Athena supports various S3 file-formats including CSV, JSON, parquet, orc, and Avro. This service is very popular since this service is serverless and the user does not have to manage the infrastructure. ![]() You can read more on Redshift features here.Īthena is a serverless analytics service where an Analyst can directly perform the query execution over AWS S3. In Redshift, both compute and storage layers are coupled, however in Redshift Spectrum, compute and storage layers are decoupled. The leader node internally communicates with the Compute node to retrieve the query results. You can watch a short intro on Redshift here:ĭata is stored in the nodes and when the Redshift users hit the query in the client/query editor, it internally communicates with Leader Node. The tables are in columnar storage format for fast retrieval of data. Redshift is purely an MPP data warehouse application service used by the Analyst or Data warehouse engineer who can query the tables. Redshift Vs Athena: Feature Comparison Amazon Redshift Features Athena is well integrated with AWS Glue Crawler to devise the table DDLs Redshift Vs Athena Comparison Athena supports almost all the S3 file formats to execute the query. Athena only supports S3 as a source for query executions. Athena query DDLs are supported by Hive and query executions are internally supported by Presto Engine. Since Athena is a serverless service, the user or Analyst does not have to worry about managing any infrastructure. Slices are nothing but virtual CPUs Athena OverviewĪmazon Athena is a serverless Analytics service to perform interactive queries over AWS S3. Clients can only interact with a Leader node. Redshift comprises Leader Nodes interacting with Compute nodes and clients. Redshift data warehouse tables can be connected using JDBC/ODBC clients or through the Redshift query editor.
