+- Asynchronous materialized views are only supported for use in the Nereids 
optimizer, [Nereids optimizer](../nereids.md)
+- Currently, only `OlapTable` is supported for determining whether the 
materialized view and base table are synchronized. For other appearances, they 
are directly considered synchronous. For example, the base tables of 
materialized views are all appearances. When querying `mv_infos()`, 
SyncWithBaseTables will always be 1 (true). When refreshing the materialized 
view, it is necessary to manually refresh the specified partition or specify 
`complete` to refresh all partitions

Review Comment:
   determining -> judging. appearances -> external table? You can use products 
like Chat GPT to obtain more accurate translation results.
