PostGraphQL VS OData

• Automatic Schema Generation
  PostGraphQL automatically generates a GraphQL schema based on the structure and relationships within your PostgreSQL database, reducing the need for manual schema definition and maintenance.
• Efficiency
  By leveraging PostgreSQL functions, PostGraphQL can efficiently execute complex queries directly within the database, leading to potentially faster query performance.
• Consistent API
  The tool ensures a consistent and predictable API is generated from the database schema, which can simplify client-side development and integration.
• Support for PostgreSQL Features
  PostGraphQL takes advantage of PostgreSQL's advanced features such as triggers, views, and stored procedures, allowing for rich and powerful API capabilities.

Possible disadvantages

• Complexity with Custom Logic
  Implementing custom business logic can become complex, as it often requires embedding logic within the database using SQL or PL/pgSQL, which may not be as straightforward as writing it in a standalone application server.
• Overhead for Simple Applications
  For simple applications with limited database interactions, PostGraphQL might introduce unnecessary complexity and overhead compared to using a traditional REST API or a simpler GraphQL server.
• Learning Curve
  Developers unfamiliar with PostgreSQL might face a learning curve in leveraging the full capabilities of PostGraphQL, particularly if they're not accustomed to database-centric application design.
• Tight Coupling with Database
  PostGraphQL closely ties the API design to the database schema, which may reduce flexibility in cases where the API design needs to evolve independently of the database structure.

• Interoperability
  OData allows for standardized communication between diverse systems by providing a common protocol, which improves data sharing and collaboration across different platforms.
• Simplicity
  Using HTTP for query operations, OData simplifies data access through RESTful APIs, making it accessible for developers familiar with web services.
• Flexibility
  OData supports a wide range of data formats such as JSON, XML, and AtomPub, giving developers the flexibility to choose the best format for their needs.
• Data Querying
  The protocol allows complex querying capabilities directly in the URL through a standard syntax, which simplifies data retrieval and manipulation.
• Integration
  OData is well-suited for integration with other Microsoft products and services, as well as many enterprise systems, due to its wide adoption and support.

Possible disadvantages

• Overhead
  While offering a standardized approach, OData can introduce additional overhead with metadata-heavy responses, which can be inefficient for larger datasets.
• Complexity in Implementation
  Despite its simplicity in concept, implementing OData services can become complex, particularly when customizing or extending beyond basic functionalities.
• Limited Industry Adoption
  Compared to other RESTful services, OData's adoption outside of Microsoft and SAP environments is relatively limited, which can restrict its use in certain industries.
• Scalability Concerns
  OData services, when not implemented efficiently, may face scalability issues under high load due to verbose nature and complex processing requirements.
• Security Challenges
  Ensuring security in OData services requires additional considerations and may involve more complex configurations to handle authentication and authorization.

  What do you mean locally? Hasura is OSS, and you can run it locally (you have autogenerated SQL statements) Here you can just use Nhost and its CLI; Alternatives are https://github.com/graphile/postgraphile or dgraph as you mentioned.... - Source: Hacker News / almost 4 years ago
