Documentation

data CreateFromSourceRelationship (b :: BackendType) Source #

Argument to the _create_remote_relationship and _update_remote_relationship families of metadata commands.

For historical reason, this type is also used to represent a db-to-rs schema in the metadata.

data PartiallyResolvedSource b Source #

Internal intermediary step.

We build the output of sources in two steps: 1. we first resolve sources, and collect the core info of their tables 2. we then build the entire output from the collection of partially resolved sources

We need this split to be able to resolve cross-source relationships: to process one source's remote relationship, we need to know about the target source's tables core info.

This data structure is used as an argument to AnyBackend in the backend-agnostic intermediary collection, and used here to build remote field info.

buildRemoteFieldInfo Source #

Arguments

:: QErrM m
=> LHSIdentifier	The entity on which the remote relationship is defined
-> HashMap FieldName lhsJoinField	join fields provided by the LHS entity
-> RemoteRelationship	definition of remote relationship
-> HashMap SourceName (AnyBackend PartiallyResolvedSource)	Required context to process cross boundary relationships
-> PartiallyResolvedRemoteSchemaMap	Required context to process cross boundary relationships
-> m (RemoteFieldInfo lhsJoinField, Seq SchemaDependency)	returns 1. schema cache representation of the remote relationships 2. the dependencies on the RHS of the join. The dependencies on the LHS entities has to be handled by the calling function

Builds the schema cache representation of a remote relationship TODO: this is not actually called by the remote relationship DDL API and is only used as part of the schema cache process. Should this be moved elsewhere?
