Brian Clozel e83793ba7f Batch SSE events writes when possible Prior to this commit, the `SseEventBuilder` would be used to create SSE events and write them to the connection using the `ResponseBodyEmitter`. This would send each data item one by one, effectively writing and flushing to the network for each. Since multiple data lines are prepared by the `SseEventBuilder`, a typical write of an SSE event performs multiple flushes operations. This commit adds a method on `ResponseBodyEmitter` to perform batch writes (given a `Set<DataWithMediaType>`) and only flush once all elements of the set have been written. This also applies in case of early writes, where now all buffered elements are written then flushed altogether. Fixes gh-30912	1 year ago

Brian Clozel e83793ba7f Batch SSE events writes when possible

Prior to this commit, the `SseEventBuilder` would be used to create SSE
events and write them to the connection using the `ResponseBodyEmitter`.
This would send each data item one by one, effectively writing and
flushing to the network for each. Since multiple data lines are prepared
by the `SseEventBuilder`, a typical write of an SSE event performs
multiple flushes operations.

This commit adds a method on `ResponseBodyEmitter` to perform batch
writes (given a `Set<DataWithMediaType>`) and only flush once all
elements of the set have been written.
This also applies in case of early writes, where now all buffered
elements are written then flushed altogether.
