Request for single table import option in Web Service As Relational web service ------------------------------------------------------------------------------- Key: TEIIDDES-319 URL: https://jira.jboss.org/jira/browse/TEIIDDES-319 Project: Teiid Designer Issue Type: Feature Request Affects Versions: Future Environment: 5.5.3 GA on Linux Reporter: Greg Haber Assignee: Barry LaFond This is a longer term feature request - not expecting any near term resolution. It would be great if the web service as relational importer could have an option to model a web service with a single table representing both the request and response, instead of as separate tables as today. Not sure if it makes sense to allow this for heirarchical response web services, or only simple ones returning a flat schema. Whenever possible I always manually model web service connections this way because of the pros - but would be much better if the importer would do it for me. Pros: -Would avoid multiple queries to web service connector for a single web service call (since XML-Relational connectors don't support join pushdown) - simpler query plans -With that single call it lessens use/paves way for disabling the XML-Relational connector internal doc cache (which, at least in 5.0SP2, was a _big_ bottleneck in the field with concurrent calls to the same web service, if the web service takes more than a few seconds to respond - I believe because the whole doc cache is locked on both read and write, effectively resulting in single threaded and blocking behavior. Anyway, just speculating on the cause, but it is established that in 5.0SP2 that single-table web services were much faster than multi-table ones). -Would work in preview Cons: -Does not logically represent the way web services actually work -Confusing as it jumbles together elements from two XML docs in a single relational base table
