[GitHub] [iotdb] MarcosZyk opened a new pull request, #5686: New schema tree traverse

[GitBox <gi...@apache.org>]

MarcosZyk opened a new pull request, #5686:
URL: https://github.com/apache/iotdb/pull/5686

   ## Description
   
   ### Implement new schemaTree traverse algorithm
   The old algorithm has some bugs on processing internal ```**``` in pathPattern. A new algorithm is implemented to fix those bugs and provide better performance.
   
   ### Establish common traverse framework
   Use ```Template method design pattern``` to separate algorithm and concrete result element process. The algorithm could be reuse and extend by extending the ```AbstractTreeVisitor``` and overriding related methods.
   
   ### Implement GetMatchedDevices
   Implement ```schemaTree.getMatchedDevices``` for ```align by device``` query process.
   
   ### Future work
   Integrate the MTree traverser into this tree visitor framework, implement ```SchemaReader``` based on this framework and rewrite the schemaRegion query interface.
