Apache Impala (incubating) vs. Amazon Redshift: S3 Integration, Elasticity, Agility, and Cost-Performance Benefits on AWS

Categories: Cloud Impala Performance

As measured across multiple dimensions (see analysis below), Impala provides a better cloud-native experience than Redshift for a number of common use cases.

Impala 2.6 brings read/write support on Amazon S3, which provides cloud capabilities such as direct querying of data from S3, elastic scaling of compute, and seamless data portability and flexibility that are unique amongst cloud-based analytic databases. With more and more users looking to deploy and run in public-cloud environments,

Apache Impala (Incubating) on Amazon: Performance and Cost Considerations for S3 vs. EBS

Categories: Cloud Impala Performance

The benchmark testing results detailed below can help you make an informed decision about AWS storage options for Impala.

In a recent post, you learned how Impala 2.6 on S3 delivers cloud-native features unmatched by other analytic databases in the cloud. With support to read/write data from Amazon S3, Impala provides cloud capabilities such as direct querying of data from S3, elastic scaling of compute, and seamless data portability and flexibility not found on other cloud-based analytic databases,

Resolving Lock Contention in Apache Solr: A Performance-Analysis Detective Story

Categories: Performance Search Testing

This case study is an instructive example of how performance analysis is a multi-faceted process that often leads one in surprising directions. 

Apache Solr Near Real Time (NRT)  Search allows Solr users to search documents indexed just seconds ago. It’s a critical feature in many real-time analytics applications. As Solr indexes more and more documents in near real time, end-user expectations for performance get higher and higher.

However,
