Here are a few questions that need clarification:
1. Is there a need to support specifying a version? @matthewmturner
2. Where should the parameters for object storage, such as `access-key-id`
and `secret-access-key` for S3, be obtained from? @liurenjie1024
- `StaticTable` relies on `FileIO`.
- For those using DataFusion, they can pre-construct an `AmazonS3
ObjectStore` and register it in `RuntimeEnv`. In the implementation of
`TableProviderFactory`, the `ObjectStore` can be obtained from the location of
the external table via the provided `Session`. However, `FileIO` cannot use
`ObjectStore`.
**Proposed Solution**
**For the first question:**
1. By default, use the latest version.
2. [Optional] Support specifying a version, for example: `CREATE EXTERNAL
TABLE my_table STORED AS ICEBERGTABLE LOCATION '/path/to/table' OPTIONS
('version' '1');`
**For the second question:**
1. Specify the relevant parameters in the `OPTIONS` block of the DDL
statement.
2. Refactor `FileIO` so that it also can rely on `ObjectStore` as its
storage backend.
3. Register the FileIO used to read the location via a global variable.
