### What OpenDD flags are now stored as a Set of a new Flag enum type. This allows us to enumerate the flags easily (via the `IntoEnumIterator` trait), which will be useful in the future to generate a list of compatibility dates. The new OpenDdFlags set type deserializes to exactly the same JSON as before, with one exception: any "false" flags (ie. flags not in the set) are not serialized. This should help newer MBS build metadata that is compatible with older engine versions that don't understand newer flags that are disabled and therefore irrelevant. ### How The main change is in `crates/open-dds/src/flags.rs` where a new OpenDdFlags type has been created. It is just a wrapper around a `BTreeSet` of our new `Flag` enum. It has a custom `Serialize`, `Deserialize` and `JsonSchema` implementation that performs the serialization we want, and also manually creates the same JsonSchema as we previously had that matches the serialization. Unit tests at the bottom of that file perform roundtrip tests and check that the serialization does what we want. Now that the flags are not a struct and are instead a set, all usages change to using `.contains`. You can see this peppered through metadata_resolve. In MBS, `crates/cloud/v3-metadata-build-service/src/build/compatibility/flags.rs` is where we rework the compatibility date handling to leverage the enum. We perform a pattern match on it to ensure there's a compatibility date added for new flags and we now automatically compute the correct flags to set based on the date using that match and iterating over the flags.

Hasura GraphQL Engine
The Hasura engine is an open source project which supercharges the building of modern applications by providing access to data via a single, composable, secure API endpoint.
Hasura V3
The future of data delivery is GA: Supporting PostgreSQL (and its flavors), MongoDB, ClickHouse, and MS SQL Server. Also supports writing custom business logic using the Typescript, Python, and Go Connector SDKs. Here is the recommended Getting Started guide on DDN.
The Hasura v3 engine code, which powers Hasura DDN, is in the v3 folder of this repo. You can find more detailed
information about in this v3 README.
The Hasura DDN architecture includes Data Connectors to connect to data sources. All Hasura connectors are also available completely open source. Check out the Connector Hub which lists all available connectors.
Hasura V2
Hasura V2 is the current stable version of the Hasura GraphQL Engine. Please find more
detailed information about the V2 Hasura Graphql Engine in the v2 folder and this README.
Cloning repository
This repository is a large and active mono-repo containing many parts of the Hasura ecosystem and a long git history, that can make the first time cloning of the repository slow and consume a lot of disk space. We recommend following if you are facing cloning issues.
Shallow clone
This will only clone the latest commit and ignore all historical commits.
git clone https://github.com/hasura/graphql-engine.git --depth 1
Git checkout with only Hasura V3 engine code
git clone --no-checkout https://github.com/hasura/graphql-engine.git --depth 1
cd graphql-engine
git sparse-checkout init --cone
git sparse-checkout set v3
git checkout @
This checkouts the top level files and only the v3 folder which contains the Hasura V3 Engine code.
