3.4.2.5 Message: ChannelStreamingStart
| Topic Version | 1 | Published | 10/31/2016 | |
| For Standard | ETP v1.1 | |||
Sent from a consumer to producer to request that the producer begin streaming one or more channels. The startIndex value is a union of possible points to begin the stream (latest, n points back from now, etc.). For more information on these options, see 3.3.16.1 Record: ChannelStreamingInfo.
If any of the channels are already in a streaming state, the producer MUST send one EINVALID_STATE exception, but MUST still start streaming all of the channels that are valid.
