[GitHub] [age] OpenCoderX opened a new issue, #381: does age introduce a unique on disk data structure that stores the graphs?
OpenCoderX opened a new issue, #381:
URL: https://github.com/apache/age/issues/381
Is there a distinct on disk data structure used to store the graphs or do we transpile cypther to sql then execute the sql against the relational table data structures?

no. AGE has the ability to meet traditional queries where it is necessary and it can surpass relational queries. We need ne details to help you.

Thank you for the explanation, I'm weighing options to replace neo4j. Given that AGE uses typical relational tables, am I to assume that I can expect relational performance when executing deep graph queries?

I think it is done using the Postgres relational tables.
The `ag_graph` and `ag_label` is stored as a relation under `ag_catalog` scheme
```
demo=# \dt
List of relations
Schema | Name | Type | Owner
------------+----------+-------+-------
ag_catalog | ag_graph | table | imran
ag_catalog | ag_label | table | imran
public | company | table | imran
public | employee | table | imran
(4 rows)
```
As you can see that my new graph `cypher` is stored as schema. The `id` and `properties` data of the nodes is saved in the table name `_ag_label_vertex`.
So I think it will be like, first we parse the `cypher` function and then perform corresponding psql operations defined.
