TTL Snapshot Refresh doesn't fully reload Internal MV if the user
query contains LIMIT
--------------------------------------------------------------------------------------
Key: TEIID-2795
URL:
https://issues.jboss.org/browse/TEIID-2795
Project: Teiid
Issue Type: Bug
Components: Query Engine
Affects Versions: 7.7.8
Reporter: Debbie Steigner
Assignee: Steven Hawkins
using the cache hint to automatically trigger a full snapshot refresh after a specified
time to live (TTL)[1]. The TTL works but if the user query that is run contains a LIMIT
clause the refresh load uses the LIMIT and doesn't completely load the internal MV and
fails load.
Sequence of events
1) Execute the query to initiate the internal MV load
2) After caching, issue the same query but with limit of 10,000 to test it is hitting the
cache
3) Wait for 5 minutes for TTL to expire
4) Re-issue the same query with limit of 10,000 and i can see the state change to
reloading but once the query has finished fetching 10,000 from data source it terminates
and the MV state changed to failed_load. I would have expected the MV to continue to load
to rehydrate the cache and the query should be fetching the data from the stale cache. But
this is not the case ...
