   We have 4 kinds of data(table). They are `record`, `metadata`(inventory + lock), `metrics` and `none stream`. `none stream` is also `record`(currently).
   
   As we know, metadata is not very large in usually. As @wu-sheng said, they don't need to split sharding. The others need to have sharding.
   
   Besides this, most of tables are `metrics`. And they have several kinds of downsampling(month, day, hour, minute and second). By default, the unit is second, so it does not have a time unit as the suffix.
