aykut-bozkurt a6a7271e63 Query generator test tool (#6686) ... - Query generator is used to create queries, allowed by the grammar which is documented at `query_generator/query_gen.py` (currently contains only joins). - This PR adds a CI test which utilizes the query generator to compare the results of generated queries that are executed on Citus tables and local (undistributed) tables. It fails if there is an unexpected error at results. The error can be related to Citus, the query generator, or even Postgres. - The tool is configured by the file `query_generator/config/config.yaml`, which limits table counts at generated queries and sets many table related parameters (e.g. row count). - Run time of the CI task can be configured from the config file. By default, we run 250 queries with maximum table count of 40 inside each query.		2023-04-23 20:28:26 +03:00
