[teiid-issues] [JBoss JIRA] (TEIID-2062) Produce an embeddable Teiid engine
[
https://issues.jboss.org/browse/TEIID-2062?page=com.atlassian.jira.plugin...
]
Steven Hawkins resolved TEIID-2062.
-----------------------------------
Resolution: Done
modified executeQuery to methods on the Connection interface EmbeddedConnection. This
allows queries to share session cache entries, be non-query commands, be prepared, etc.
and use other jdbc facilities such as the continuous/async logic.
The usage is to obtain a connection off of the TeiidDriver:
Connection c = embeddedServer.getDriver().connect("jdbc:teiid:vdb", new
Properties());
EmbeddedConnection ec = c.unwrap(EmbeddedConnection.class);
...
At this point we'll consider the initial phase of development complete and any
additional work can be spawned under new JIRAs.
Produce an embeddable Teiid engine
----------------------------------
Key: TEIID-2062
URL: https://issues.jboss.org/browse/TEIID-2062
Project: Teiid
Issue Type: Enhancement
Components: Embedded
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 8.1
Teiid's federation and query processing features are of use to several other
projects. An embeddedable form is desired such that:
- the application server is not required
- queries could be issued in the engine object model to by-pass parsing/validation and
results retrieved without the need for JDBC
- new translators could be added
The following would be open for discussion:
- the inclusion of saxon/xom/nux for SQL/XML processing
- if the general deployment logic would be needed, or if just a single dynamic vdb is all
that is needed
See the org.teiid.jdbc.FakeServer in the test-integration/common module for a rough
approximation at the entry point for a embeddable server. Note that it is more geared at
unit testing JDBC/ODBC rather than providing the features needed here.
