Batch Processing

When the user needs to process large amount of images but does not require realtime responses, it is recommended to use ProductAI Batch Processing.
The advantages are:

No need to call API mutiple times, just upload all the dataset through Console/SDK/API in one operation.
The ProductAI backend leverages batch-optimizing strategy, users will experience a much shorter total process time.
The ProductAI backend resources will be scheduled with an on-demand scheme, let’s save the Earth together.

Supported Services

Be noticed, currently part of the ProductAI services can be scheduled in Batch Processing. Here are the supported services:

User can fetch supported service list through SDK/API
