   @XuQianJin-Stars 
   Is this right? 
   ```java
     public static final ConfigProperty<String> HIVE_SUPPORT_TIMESTAMP_TYPE = 
ConfigProperty
         .key("hoodie.datasource.hive_sync.support_timestamp")
         .defaultValue("true")
         .deprecatedAfter("0.12.0")
         .withDocumentation("'INT64' with original type TIMESTAMP_MICROS is 
converted to hive 'timestamp' type. "
             + "From 0.12.0, 'timestamp' type will be supported and also can be 
disabled by this variable. "
             + "Previous versions keep being disabled by default.");
   ```
   If there's no problem, I'll change all the other descriptions.
