In this blog post, I will show how to configure and deploy Athena Federated Query to query Aurora PostgreSQL data source. AWS provides prebuilt Athena data source connectors for various data sources which make it easier to deploy and use Federated Query. of existing codebase to Golang and database to AWS RDS PostgreSQL instance. When using Federated Query, Athena uses data source connectors that executes AWS Lambda functions to run the federated queries and fetch results. Orchestrated workflows using AWS Step Functions, AWS Lambda and AWS API. When Amazon RDS supports a new version of a database engine, you can upgrade your DB instances to the new version. Using Athena Federated Query, you can run SQL queries across data stored in relational, non-relational, object, and custom data sources. In such scenarios, you can use Athena Federated Query to query data from sources other than Amazon S3. Note: Items with a bracketed exclamation mark () have consistently appeared on mock exams. 2018 Whats New in Amazon Aurora AWS re:Invent 2018: Accelerate Oracle to Aurora PostgreSQL Migration (GPSTEC313) AWS re:Invent 2018: Building Your. My source material was primarily the A Cloud Guru course and the AWS documentation. There can be scenario where you many want to extract data from multiple data sources like PostgreSQL database or Amazon Redshift or others when building an end-to-end pipelines. This is a rather rough outline that contains key points relevant to the Amazon Certified Solutions Architect (Associate) exam. conn nnect (hosthostname, userusername, passwordpassword, dbnamedbname, connecttimeout50) I did like this. ![]() Athena service can also be part of data pipeline to fetch and process data. I wrote a simple lambda function in python to fetch some data from AWS RDS. They benefit from being stateless and therefore enable efficient scaling as workloads increase. ![]() In most cases, Amazon Athena is used to run ad-hoc queries to get results from data stored in Data Lake created on top of Amazon S3. Creating a REST API for Amazon DocumentDB (with MongoDB compatibility) with Amazon API Gateway and AWS Lambda Representational state transfer (REST) APIs are a common architectural style for distributed systems. Amazon Athena is an interactive query service that enables users to analyze data in Amazon S3 using standard SQL.
