Hello all, Currently, when user creates a datamap, system will store the datamap metadata in a configurable system folder in HDFS or S3. And also, since we use same naming conventions as datamap name for datamapschema, users cannot create datamap with same name which is already present in storage.
System folder currently holds the following files, 1. DataMapSchema -> a json file containing schema for one datamap. 2. DataMapStatus -> status for each datamap In cloud scenarios, when one user creates SYSTEM_FOLDER and stores metadata for materalized views and index datamap's such as bloom and lucene, other user's are not able to access the SYSTEM_FOLDER. In order to support multi-tenancy for datamaps, i am planning to move system_folder under each database level, so that users can access it. As system folder is moved across database folder,users can create datamap with same name under different databases. Datamaps will be saved to database folder specified while creating datamap. Any suggestions/inputs from the community is appreciated. Thanks Indhumathi
