I wonder if we can make it as an envd target so we can get rid of yaml?

| The access pattern of most dataset is write once, read multiple times, and concurrently. Therefore |

Missing some additional context after "therefore"?

How about semantic versioning?

What is this version for? How is this different from the version below?
| version: "0.0.1-sample" | ||
| sources: |

What if there are multiple versions for different sources?

Is there any implementation plan for this? Are you aware of any existing solutions that could support multiple sources? This might be helpful as a reference for the range of sources: https://kubernetes.io/docs/concepts/storage/volumes/#volume-types

What are the different purposes of the YAML above and this envd syntax?

Data function support
Summary
To provide mount data support for envd
Goals
Design a unified, declarative interface and underlying architecture to provide dataset in the development environment in a scalable way

Common Scenarios
Possible sources
Possible form
Access Pattern
The access pattern of most dataset is write once, read multiple times, and concurrently. Therefore
Possible versions/tags
We can have a new standard on how to version the data like semver
Proposal
Each version of dataset is immutable. By assuming the data is immutable, we can cache the data and make replication easily, to increase the read throughput in multiple ways.
Usage
User need to create the dataset beforehand. Than declare mounting in the build.envd file.
User can create multiple dataset with the same name, but need to be different versions
mnist.yaml
build.envd
