Concurrent Queries Spark clusters in HDInsight support concurrent queries. This capability enables multiple queries from one user or multiple queries from various users and applications to share the same cluster resources. Caching on SSDs You can choose to cache data either in memory or in SSDs at...
PySpark is a Python API for Spark released by the Apache Spark community to support Python with Spark. Using PySpark, one can easily integrate and work with RDDs in Python programming language too. There are numerous features that make PySpark such an amazing framework when it comes to working...
Governance setting for Power BI cache refreshes This release introduces the ClientCacheRefreshPolicy property, which overrides caching dashboard tile data and report data for initial load of Live connect reports by the Power BI service. To learn more, see General Properties. Online attach Online attac...
The HDInsight implementation uses the scale-out architecture of HBase to provide automatic sharding of tables. And strong consistency for reads and writes, and automatic failover. Performance is enhanced by in-memory caching for reads and high-throughput streaming for writes. HBase cluster can b...
All views in Azure Databricks compute results from source datasets as they are queried, leveraging caching optimizations when available. Delta Live Tables does not publish views to the catalog, so views can be referenced only within the pipeline in which they are defined. Views are ...
Apache Spark is an open-source, distributed processing system which utilizes in-memory caching and optimized query execution for faster queries.
Spark loads data by referencing a data source or by parallelizing an existing collection with the SparkContext parallelize method of caching data into an RDD for processing. Once data is loaded into an RDD, Spark performs transformations and actions on RDDs in memory—the key to Spark’s speed...
