[teiid-issues] [JBoss JIRA] (TEIID-4858) hive translator is extremely slow

Michael Echevarria commented on TEIID-4858:
-------------------------------------------
Looking at the execution plan it shows that it is selecting explicit columns, not a select
*. When executing the VDB, selecting * against both sources and selecting individual
columns against both sources is very quick. The delay comes when deploying the VDB and
accessing remotely
hive translator is extremely slow
---------------------------------
Key: TEIID-4858
URL: https://issues.jboss.org/browse/TEIID-4858
Project: Teiid
Issue Type: Bug
Components: JDBC Connector
Affects Versions: 8.12.9.6_3
Environment: Tested against JDV 6.3.4 and the Cloudera quickstart 5.8 VM with the
Cloudera sample data loaded into hive
Reporter: Michael Echevarria
Assignee: Steven Hawkins
When querying a table through the hive translator the results take close to 30 seconds to
return.
When querying a table through jdbc default results take under 1 second to return.
Both use the same underlying jboss server datasource.
