deepcase materialized-path
Associative, multidirectional, multiparental materialized-path realization.
To understand how to use it for your own purposes - look at migrations and tests.
- [x] Associative links structure base trigger table.
- [x] Column names configuration. You can use your structure, not only id/from_id/to_id with Trigger class options:

See multidirectional migrations and tests for details. - [x] Customizable id field type with Trigger class option:
id_type. - [x] PostgreSQL only for now.
- [x] Hasura support, but not required.
- [x] Grouping support. Not only one tree layer for one storage. You can separate multiple tree conditions with Trigger class options:
iteratorInsertDeclare,iteratorInsertBegin,iteratorInsertEnd,iteratorDeleteArgumentSend,iteratorDeleteArgumentGet,iteratorDeleteDeclare,iteratorDeleteBegin,iteratorDeleteEnd,groupInsert,groupDelete,additionalFields,additionalData. - [ ] Benchmarks.
