This PR enhances Polypheny with the ability to serialize arbitrary query plans into a textual representation called PolyAlgebra. This is the foundation for the new framework-based plan editor system in the UI. The required functionality is provided via new HTTP endpoints and websocket messages.
Changes
Removed the old query plan builder
Replaced the old InformationQueryPlan with InformationPolyAlg for the new plan editor
Changed the order of information pages for executed queries to be grouped by statements
Features
Ability to serialize AlgNodes to PolyAlgebra (textual or structured representation)
Parser for reconstructing the AlgNodes from PolyAlgebra
for physical: Enumerable and Jdbc (can be used as reference implementation for the remaining AlgNodes)
Tests
PolyAlgParsingTest: verifying consistent serialization and reconstruction of query plans for various queries
ToDo
[ ] Actions do not yet run successfully. Locally, all tests succeed...
[ ] @datomo Fix return type inference for CYPHER_EXTRACT_FROM_PATH, then enable corresponding tests in PolyAlgParsingTest
[ ] Register all remaining physical AlgNodes (register declaration, implement bindArguments() and static create() method). This can also be done at a later point, as it is only required for the rare use case of editing physical plans.
