Hello Steven,
ok understood. I have now used the Eclipse Database view to do a select * within a
Scrapebook. I hope that it internally does not add some type of top statement to my
query.
The result of the query says success and gives me
Elapsed Time: 0 hr, 0 min, 0 sec, 76 ms.
So I have no feeling if this is slow or fast. As a matter of principle the dataset in the
table is not very large. About 64mb csv file with about 650.000 rows which I imported to
the table and the database (in Docker) and eclipse running on the same mac. I did some
tests previously with only 10.000 rows involved, this also did result in an error.
Currently I proceed with development efforts based on a dataset of just 100 rows. I hope I
find a solution on this soon :( Might there be some other issues involved when I run teiid
in a docker container? By default in Docker there are no resource constraints set, hence
at least this should be fine. Is there some way to get more usable information out of the
Wildfly Server on what is happening there?

When querying a larger dataset, teiid answers with 504 Gateway
Time-out and throws exception

Key: TEIID-5643
URL: https://issues.jboss.org/browse/TEIID-5643
Project: Teiid
Issue Type: Bug
Affects Versions: 11.2.1
Reporter: Christoph John
Assignee: Steven Hawkins
Priority: Major
Attachments: Heap Dump analysis tool.pdf
Please note, I am using Teiid 11.2.0 and not 11.2.1 as specified above in this ticket. I
was not able to select a version 11.2.0.
The issue: I tried to query a table with a larger amount of records (about 600.000
records in the table). Teiid responds with
504 Gateway Time-out. The server didn't respond in time.
If Teiid tries to respond with 600.000 entries to such a request, it is reasonable that
it runs out of memory or other weird things happen. However, I would expect that in such a
case Teiid just answers with a fixed amount of records, say for example 1000, and provides
a kind of curser to enable subsequent requests to retrieve more data.
I am currently trying to find a workaround for the issue, as the issue blocks my work. Is
there maybe a kind of configuration option that I have to set explicitly for such a kind
of behavior I previously sketched?
Further note: When I send such a kind of select * request on the table to Teiid, I am
also not able for a certain time interval, about a minute, to get a responds to different
queries which select a single element on the mentioned table. Such a request then also
results in a 504 Gateway Time-out.
