Review Comment:
nit: Would it be helpful to add this in the option description for generated
config docs?
```
public static final ConfigOption<Integer> GLOBAL_INDEX_THREAD_NUM =
key("global-index.thread-num")
.intType()
.defaultValue(32)
.withDescription(
"The maximum number of concurrent threads for
global index I/O.");
```
`+ Must be greater than 0.`
