Steven Hawkins commented on TEIID-3622:
---------------------------------------
Teiid does support a limited merge statement, which is similar to an upsert. We would have
to update the engine/translators to support pushdown to fully address this issue.
Otherwise we either should just document the upsert behavior (I believe mongodb is
similar) or we'd have to just not support updates (although delete would be fine, we
can't specify just supporting it currently).
HBase translator - INSERT could rewrite the data
------------------------------------------------
Key: TEIID-3622
URL:
https://issues.jboss.org/browse/TEIID-3622
Project: Teiid
Issue Type: Bug
Affects Versions: 8.7.1.6_2
Environment: Hbase: 1.1.1
Phoenix: 4.5.0-HBase-1.1
Reporter: Juraj DurĂ¡ni
Assignee: Steven Hawkins
The HBase translator translates INSERT as UPSERT, which is an "alias" for both
INSERT and UPDATE statement. It means, if user issues same INSERT statement twice, no
exception is thrown [1]. I expect that [2] could rewrite the data.
*Additional note*: I was not able to verify my assumption because of
https://issues.jboss.org/browse/TEIID-3619
[1]
INSERT INTO smalla (intkey) VALUES (55) is translated as UPSERT INTO smalla (intkey)
VALUES (55)
http://phoenix.apache.org/language/index.html#upsert_values
[2]
INSERT INTO smalla (intkey, name) VALUES (1, 'name1')
INSERT INTO smalla (intkey, name) VALUES (1, 'name2')
