#SIZEWISE SPARK HOW TO#

Node SizesДЄ Spark pool can be defined with node sizes that range from a Small compute node with 4 vCore and 32 GB of memory up to a XXLarge compute node with 64 vCore and 512 GB of memory per node. All worker nodes run the Spark Executor service. All nodes run services such as Node Agent and Yarn Node Manager. The head node runs additional management services such as Livy, Yarn Resource Manager, Zookeeper, and the Spark driver. If you expect to enable this feature in the future, ensure that your Synapse workspace is created in an isolated compute supported region.ДЄpache Spark pool instance consists of one head node and two or more worker nodes with a minimum of three nodes in a Spark instance. The isolated compute option can be enabled or disabled after pool creation although the instance may need to be restarted. The Isolate Compute option is only available with the XXXLarge (80 vCPU / 504 GB) node size and only available in the following regions.

Isolated compute option is best suited for workloads that require a high degree of isolation from other customer's workloads for reasons that include meeting compliance and regulatory requirements. The Isolated Compute option provides additional security to Spark compute resources from untrusted services by dedicating the physical compute resource to a single customer.

#SIZEWISE SPARK HOW TO#

You can read how to create a Spark pool and see all their properties here Get started with Spark pools in Synapse Analytics Isolated Compute Charges are only incurred once a Spark job is executed on the target Spark pool and the Spark instance is instantiated on demand. There are no costs incurred with creating Spark pools. A Spark pool in itself does not consume any resources. These characteristics include but aren't limited to name, number of nodes, node size, scaling behavior, and time to live. A Spark pool is a set of metadata that defines the compute resource requirements and associated behavior characteristics when a Spark instance is instantiated.
