public static class ArxDynamoPreLoad

Methods

• static Task<ArxSchemaCatalog> LoadAsync(this ArxPreLoadTable preload, IAmazonDynamoDB client, ArxDynamoModel model, Action<ArxSchemaCatalogBuilder>? configure = null, CancellationToken cancellationToken = default)

  Reads, once at startup, the key schema of each requested entity's table (DescribeTable) and returns a schema catalog: the entity's key as a business key and the key attributes' types as columns. DynamoDB stores no other types, so the other attributes are the ones configure declares (.Column); with Strict they are the allow list.

  Parameter	Type	Description
  preload	this ArxPreLoadTable	The entities to read.
  client	IAmazonDynamoDB	The DynamoDB client.
  model	ArxDynamoModel	The tables' layout.
  configure	Action<ArxSchemaCatalogBuilder>?= null	Declarations of your own: each entity's id, the columns and their types (DynamoDB keeps none), lookups, versions; null for none. They are kept, and the preload adds only what they leave out.
  cancellationToken	CancellationToken= default	Cancels the call.
