> Now, org.apache.kylin.metadata.cachesync.CachedCrudAssist#reloadAll is using an inappropriate method to deal with MySQLJdbcMetadata.
> As the every call of reloadAt(path) will access the database, which is almost fine to HBase but really unfriendly to the MySQL(RDBMS).
> I think we should get all of the resource with single request instead of the separate request to get every resource.
