Connect, share, and query where your data sits using Amazon SageMaker Unified Studio

In this blog post, we will demonstrate how business units can use Amazon SageMaker Unified Studio to discover, subscribe to, and analyze these distributed data assets. Through this unified query capability, you can create comprehensive insights into customer transaction patterns and purchase behavior for active products without the traditional barriers of data silos or the need to copy data between systems.

Build a data lakehouse in a hybrid Environment using Amazon EMR Serverless, Apache DolphinScheduler, and TiDB

This post discusses a decoupled approach of building a serverless data lakehouse using AWS Cloud-centered services, including Amazon EMR Serverless, Amazon Athena, Amazon Simple Storage Service (Amazon S3), Apache DolphinScheduler (an open source data job scheduler) as well as PingCAP TiDB, a third-party data warehouse product that can be deployed either on premises or on the cloud or through a software as a service (SaaS).

Implement Amazon EMR HBase Graceful Scaling

Apache HBase is a massively scalable, distributed big data store in the Apache Hadoop ecosystem. We can use Amazon EMR with HBase on top of Amazon Simple Storage Service (Amazon S3) for random, strictly consistent real-time access for tables with Apache Kylin. This post demonstrates how to gracefully decommission target region servers programmatically.

Architect fault-tolerant applications with instance fleets on Amazon EMR on EC2

In this post, we show how to optimize capacity by analyzing EMR workloads and implementing strategies tailored to your workload patterns. We walk through assessing the historical compute usage of a workload and use a combination of strategies to reduce the likelihood of InsufficientCapacityExceptions (ICE) when Amazon EMR launches specific EC2 instance types. We implement flexible instance fleet strategies to reduce dependency on specific instance types and use Amazon EC2 On-Demand Capacity Reservation (ODCRs) for predictable, steady-state workloads. Following this approach can help prevent job failures due to capacity limits while optimizing your cluster for cost and performance.

Deploy real-time analytics with StarTree for managed Apache Pinot on AWS

In this post, we introduce StarTree as a managed solution on AWS for teams seeking the advantages of Pinot. We highlight the key distinctions between open-source Pinot and StarTree, and provide valuable insights for organizations considering a more streamlined approach to their real-time analytics infrastructure.
