Nathan Griffith updated DRILL-4064:
-----------------------------------
Description:
Querying works as intended if the heterogeneous database is unsharded.
In my scenario the database's shard key was not hashed, and was set to mongo's
"_id" key.
was:
Querying a sharded MongoDB database with multiple types of documents (i.e.
documents with different sets of keys) returns zero rows.
Querying works as intended if the heterogeneous database is either a.)
unsharded, or b.) culled to ensure homogeneity.
In my scenario the database's shard key was not hashed, and was set to mongo's
"_id" key.
