             Summary: Prefer:respond-async on individual requests within a batch request
                 Key: ODATA-1321
                 URL: https://issues.oasis-open.org/browse/ODATA-1321
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: Improvement
          Components: JSON Format, Protocol
    Affects Versions: V4.01_CS01
            Reporter: Ralf Handl
             Fix For: V4.01_CS02


Part 1: Protocol states in [8.2.8.8 Preference {{respond-async}}|http://docs.oasis-open.org/odata/odata/v4.01/cs01/part1-protocol/odata-v4.01-cs01-part1-protocol.html#sec_Preferencerespondasync] that
{quote}
The respond-async preference MAY be used for batch requests, but the service MUST ignore the respond-async preference for individual requests within a batch request.
{quote}

However, JSON Format states in [19.6 Asynchronous Batch Requests|http://docs.oasis-open.org/odata/odata-json-format/v4.01/cs01/odata-json-format-v4.01-cs01.html#sec_AsynchronousBatchRequests] that
{quote}
In addition to the above interaction pattern individual requests within a batch MAY be executed asynchronously if they specify the respond-async preference and if the service responds with a JSON batch response.
{quote}

Apparently the restriction in Part 1: Protocol only applies to multi-part batch requests or responses.
