Ephemeral Storage on Azure and AWS
COD now supports 1.6 TB NVMe (Non-volatile Memory Express) based cache that significantly improves the performance when you deploy COD with object storage.
Storage on S3 or ABFS can be slow, causing HBase to be slow as well. Large blockcache can solve this by keeping your most frequently accessed data on the fast local NVMe disks. Once the entitlement is enabled for your tenant, the newly created COD cluster will be automatically configured for this feature. No additional configuration is needed.
NVMe-based cache is now enabled on Azure too. It uses a high performance AMD instance type with a 2 TB NVMe disk for the worker nodes.
