Error description

  • The compilation time for federated query that involves
    nicknames and a large amount of columns could be very long. It
    results from some inefficient way to handle  columns in
    compilation. It can be hit with the following conditions:
    1) there is at least one nickname involved in the query
    2) there are a large amount of columns involved in the query
    even if the columns are from local table of the queries.
