Thanks Jingsong, Very thanks for your review and pointing out the relevant issues, the relevant issues have been updated according to your suggestions.
1. `chain-table.query.type` is merely an internal conf used to identify the usage scenarios of snapshot and delta branch and is not exposed externally. There are two usage scenarios for snapshot and delta branch, independent use and combined use as chain branch. Some details are different in different scenarios. Maybe it would be better to rename it to `chain-table.branch.internal.usage.mode` . 2. The usage of options have been updated in `Usage Method`. 3. In the doc, `t$branch_xxx` has been uniformly used to represent the branch. The doc has been updated.
