How topic_update_tbl_max_wait_time_ms and catalog_max_lock_skipped_topic_updates effects on loading metadata

[#1]

Have enyone had a deal with Impala parametrs such as topic_update_tbl_max_wait_time_ms and catalog_max_lock_skipped_topic_updates. Should I try to change them and what will it affect on?
May the reduce of the topic_update_tbl_max_wait_time_ms improve the time of loading table's metadata to the impala daemon from catalog?
If you know some recomendation or more detail information please share it.
Thank you in advance!
