[JBoss JIRA] (TEIID-2868) Provide Aggregation function support in Accumulo translator

by Ramesh Reddy (JIRA)

Ramesh Reddy created TEIID-2868: ----------------------------------- Summary: Provide Aggregation function support in Accumulo translator Key: TEIID-2868 URL: https://issues.jboss.org/browse/TEIID-2868 Project: Teiid Issue Type: Enhancement Components: Misc. Connectors Affects Versions: 8.7 Reporter: Ramesh Reddy Assignee: Ramesh Reddy Currently there is no support for SUM, AVG, MIN, MAX aggregation functions, it was not clear to me right now how these can be calculated in the partitioned way Accumulo deals with row contents. This needs to be investigated and implemented. -- This message is automatically generated by JIRA.

[JBoss JIRA] (TEIID-2867) Add function support to Accumulo translator

[JBoss JIRA] (TEIID-2863) Allow both gssapi and username/password authentication on the same transport

by Steven Hawkins (JIRA)

[ https://issues.jboss.org/browse/TEIID-2863?page=com.atlassian.jira.plugin... ] Steven Hawkins commented on TEIID-2863: --------------------------------------- Correct me if I'm wrong, but aren't we fairly close with our current structure. For example if we remove the LogonImpl.logon check of the authentication type and allow the JDBC client to determine on its own whether to make a gssapi login - won't that allow for gss and password authentications on the same transport (with logically similar changes on the ODBC side)? I think we are also now, after the change to allow the vdb to declare a security domain, effectively moving toward treating the security domains setting on a transport to be interpreted as the default security domain (singular). We could do something similar with the idea of what the kerberos security domain is, that is declaring it in the vdb.xml. Or couldn't we just assume that the kerberos loginmodule is stacked in the same security domain? > Allow both gssapi and username/password authentication on the same transport > ---------------------------------------------------------------------------- > > Key: TEIID-2863 > URL: https://issues.jboss.org/browse/TEIID-2863 > Project: Teiid > Issue Type: Enhancement > Components: Server > Reporter: Steven Hawkins > Assignee: Steven Hawkins > > With GSSAPI support enabled, username/password support on the same transport is effectively disabled.

[JBoss JIRA] (TEIID-2866) Add ability to "Entity-Attribute and Graph Tables" to Accumulo Translators

by Ramesh Reddy (JIRA)

Ramesh Reddy created TEIID-2866: ----------------------------------- Summary: Add ability to "Entity-Attribute and Graph Tables" to Accumulo Translators Key: TEIID-2866 URL: https://issues.jboss.org/browse/TEIID-2866 Project: Teiid Issue Type: Feature Request Components: Misc. Connectors Affects Versions: 8.7 Reporter: Ramesh Reddy Assignee: Ramesh Reddy Accumulo data model always works with single table. However, its schema definition is flexible enough interpret to define "merged" tables depending upon the foreign key relationships defined in Teiid schema. See section 7.4 in https://accumulo.apache.org/1.5/accumulo_user_manual.html This will lead to providing some limited JOIN based queries on Accumulo with Teiid. This is similar to functionality in the MongoDB translator. -- This message is automatically generated by JIRA.

[JBoss JIRA] (TEIID-2863) Allow both gssapi and username/password authentication on the same transport

by Ramesh Reddy (JIRA)

[ https://issues.jboss.org/browse/TEIID-2863?page=com.atlassian.jira.plugin... ] Ramesh Reddy commented on TEIID-2863: ------------------------------------- Agree. Can think of reason why a transport need to be effectively combined with security at that intimate level. We can pull the security modules out of transport and define allowed security-domains at teiid configuration level that can be used across all the transports. But this would mean clients need to specify which allowed security-domain they would like to participate. We kind of do that for kerberoes. > Allow both gssapi and username/password authentication on the same transport > ---------------------------------------------------------------------------- > > Key: TEIID-2863 > URL: https://issues.jboss.org/browse/TEIID-2863 > Project: Teiid > Issue Type: Enhancement > Components: Server > Reporter: Steven Hawkins > Assignee: Steven Hawkins > > With GSSAPI support enabled, username/password support on the same transport is effectively disabled.
