But the real issue for Hive is that the way Alteryx queries the Metadata : it passes "Show table" queries for all the databases. On our cluster, it means more than 400 queries that last each avout 0.5 seconds. The user has to to wait about 4 minutes.
A solution : using an API in java to ask the Hive metastore if it exists (it may be an other tab in the In database configuration). Our cluster admin has an example of a Thrift API in java that we can give you.
Result : 2 seconds for a 38700 tables in more than 500 databases !!
