Component/s: Connector API
Query Engine
Make connector capabilites more granular.
-----------------------------------------
Key: TEIID-203
URL:
https://jira.jboss.org/jira/browse/TEIID-203
Project: Teiid
Issue Type: Feature Request
Components: Connector API, Query Engine
Affects Versions: 6.0.0
Reporter: John Doyle
Assignee: Steven Hawkins
Fix For: 6.1.0
Some connector capabilites are only available in combination with others. For example,
if you wish to support the SupportsAggregatesCount capability, you have to also support
the SupportsAggregates capability(GROUP BY and HAVING). This requirement creates
additional requirements for a connector where the source syustem cabilities do not
correspond with the relationships we have defined between capabilites.
For instance, the SQL supported by salesforce can include the count(*) function, but it
does not support GROUP BY or HAVING. Because we require c connector to support
SupportsAggregates befrore it can support count(*), the connector is required to implement
those functions if it wishes to pus down count(*).
