Announcing sample-based partitioning for AWS HealthOmics variant stores

We are excited to announce that AWS HealthOmics variant stores are now optimized to improve sample based queries saving time and query costs for customers. [AWS HealthOmics](https://aws.amazon.com/healthomics/) helps customers accelerate scientific breakthroughs by providing a fully managed service designed to handle bioinformatics and drug discovery workflows and storage at any scale. With this release, any new variant stores customer create will be automatically partitioned by the sample. This feature automatically partitions data loaded into a variant store by the sample information. Because of this partitioning, any analysis that includes sample level filtering no longer needs to scan the full set of data leading to a lower query cost and faster results. Sample based queries are common when using clinical outcome or phenotypic information to perform filtering. Sample partitioning is now supported for all new variant stores created in all regions where AWS HealthOmics is available: US East (N. Virginia), US West (Oregon), Europe (Frankfurt, Ireland, London), Asia Pacific (Singapore), and Israel (Tel Aviv). To get started using the variant store, see the AWS HealthOmics [documentation.](https://docs.aws.amazon.com/omics/latest/dev/omics-analytics.html)
