DLC supports the binding of Fusion Bucket to accelerate Query Analysis Performance. To use this feature, you need to create a Metadata Acceleration Bucket. DLC Managed Storage provides Metadata Acceleration Bucket. Use COS Bucket under the user's account. For details, please see COS>Metadata Acceleration.
When accessing the DLC Metadata Acceleration Bucket, binding of permissions is necessary. The Permission Binding Process is as follows.
2. Enter the Metadata Acceleration Bucket Configuration Page, select the bucket you want to bind, and click Configure.
Note:
Only Metadata Acceleration Buckets are displayed on the Metadata Acceleration Bucket page; ordinary buckets (buckets without the metadata acceleration feature enabled) will not be shown.
3. Click Bind to bind the data engine that needs to access this bucket to the Metadata Acceleration Bucket.
Bind computing resources of SCS
If you use SCS to stream data into the lake, and the storage written to is a Metadata Acceleration Bucket, then you need to configure access permissions for the Metadata Acceleration Bucket under Storage Configuration. Under the Tencent Cloud Product Binding section, create a new product, select Stream Computing Oceanus and the corresponding resources, then click save.
Bind computing resources of non-DLC data engines
Sometimes, the computing resources you need to access the Metadata Acceleration Bucket are not from a DLC data engine. In this case, you can configure access permissions for the Metadata Acceleration Bucket under Storage Configuration.
HDFS User Configuration is used to configure the super user of your computing resources accessing DLC, usually root/hadoop/presto/flink.
HDFS Metadata Permissions Configuration is used to configure the VPC Network Environment you allow to access DLC, usually the VPC where the computing resources of the above mentioned non-DLC data engines are located.
