    • clipAndFilterNamespace

      public VeniceProperties clipAndFilterNamespace(String nameSpace)
      Extracts properties that begin with the specified namespace.

      This method identifies all properties that start with the given namespace, removes the namespace prefix, and returns the filtered properties.

      This enables support for dynamic configurations (e.g., required by Pub/Sub clients). All properties following a namespace-based convention can be extracted and used by various adapters, such as Pub/Sub Producers or Consumers.

      Parameters:
      nameSpace - The namespace to filter properties by.
      Returns:
      A VeniceProperties instance containing properties with the namespace removed.

    • clipAndFilterNamespace

      public VeniceProperties clipAndFilterNamespace(Set<String> namespaces)
      Extracts properties that begin with any of the specified namespaces.

      This method identifies all properties that start with one of the provided namespaces, removes the matching namespace prefix, and returns the filtered properties.

      This supports dynamic configurations for various use cases, including Pub/Sub clients, messaging systems, and other configurable components. By following a namespace-based convention, different configurations can be extracted and supplied to respective adapters.

      Example structure: 

      
 "pubsub.kafka.bootstrap.servers"
 "pubsub.pulsar.service.url"
 "pubsub.warpstream.bucket.url"

      Using this method with namespaces {"pubsub.kafka.", "pubsub.pulsar."} would result in: 

      
 "bootstrap.servers"
 "service.url"
      Parameters:
      namespaces - A set of namespaces to filter properties by.
      Returns:
      A VeniceProperties instance containing properties with the matching namespaces removed.

    • getStoreProperties

      public VeniceProperties getStoreProperties(String storeName)
      Get store related properties. properties that do not begin with store- are considered common to all stores. out of properties that begins with store- , only properties that matches the store name are related to current store. These matching properties override the base properties if they are present.
      Parameters:
      storeName - name of the store
      Returns:
      Properties for the current store.
