About Data Lake Accelerator

Data Lake Accelerator is an advanced software solution designed to enhance external data processing performance and scalability.

Deployed on an Oracle-managed VM cluster, it integrates seamlessly with your Autonomous Database to accelerate the scanning and processing of external data stored in Object Stores. By automatically allocating additional CPUs based on query demands, it ensures efficient resource utilization and significantly improves query response times, offering a scalable and cost-effective solution for handling large and complex data sets.

Configure Data Lake Accelerator

Configure Data Lake Accelerator for your Autonomous Database instance during provisioning, cloning or when you update your instance.

During provisioning or cloning, the Data Lake Accelerator options are included in the advanced section. See Provision an Autonomous Database Instance and Clone an Autonomous Database Instance for more information. When modifying Data Lake Accelerator options for existing instances, use the Tools tab on the instance Details page.

To select Data Lake Accelerator options for an Autonomous Database instance, do the following:

  1. Navigate to the Data Lake Accelerator options.

  3. On the Data Lake Accelerator edit page, you can make these selections:
    • Status: Toggle Status to Disabled, to disable Data Lake Accelerator. Toggle Status to Enabled to enable.
    • ECPU count: Enter number of ECPUs, or use up and down arrows to change number of ECPUs. The default is 32 ECPUs. This is the number of ECPUs you are requesting to be allocated. You are billed for the number of ECPUs actually allocated. The range is 32 to 1024 in multiples of 32. In other words: 32, 64, 96, 128 … 1024.
    • Maximum idle time (Minutes): The default is 10 minutes and can not be changed.
