> h1. *Background*
> In my company, There are more than 80000+ hive tables in production. We will
> import hive metadata to Atlas everyday to avoid any change is missed by Hive
> Hook. This timed task causes two problem:
> 1) It costs a large amount of time(more than 20 hours at a time)
> 2) Can't use incremental export(every hive_table's updateTime was updated by
> HiveBridge)
> h1. *Solution*
> When creating or updating a hive table, the transient_lastDdlTime would be
> updated. So if the transient_lastDdlTime is the same in Atlas and metastore,
> HiveBridge should skip updating the table's metadata.
