[teiid-issues] [JBoss JIRA] (TEIID-3869) Enable Teiid to be exposed as a GIS compliant data source

    [ https://issues.jboss.org/browse/TEIID-3869?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13146727#comment-13146727 ] 

Steven Hawkins commented on TEIID-3869:
---------------------------------------

Based upon a discussion of Friday this issue will become specifically enabling support for geoserver targeting teiid odbc via their postgis configuration.  It will likely be added first to 9.0 and then back ported.  This entails several minor odbc issues, as well as support for ~10 scalar functions (one of requires a parsing change), an aggregate function, push down support, and a function alias. 

The restrictions of this include:

- no support for curved geometry types (CIRCULARSTRING, CIRCULARSTRING, MULTICURVE, COMPOUNDCURVE)
- no Teiid support for ST_Estimated_Extent (but that seems to be ok as geoserver will workaround that, and we can also provide postgis pushdown support)
- no 3d support
- no geography support
- no Teiid spatial index support

A broader amount of support, to provide full opengis / sql/mm with spatial indexes etc., is likely too much to commit to.
