|
* Takes an async iterator that emits promise-returning functions, invokes them in parallel and emits the results in the same order as the input.
|
||
|
|
*
|
||
|
|
* The final batch may be smaller than the batch size.
|
||

|
* @example
|
||
|
|
*
|
||
|
|
* ```javascript
|
||
|
|
* import parallelBatch from 'it-parallel-batch'
|
||
|
|
* import all from 'it-all'
|
||
|
|
* import delay from 'delay'
|
||
|
|
*
|
||
|
|
* // This can also be an iterator, async iterator, generator, etc
|
||
|
|
* const input = [
|
||
|
|
* async () => {
|
||
|
|
* await delay(500)
|
||
|
|
*
|
||
|
|
* return 1
|
||
|
|
* },
|
||
|
|
* async () => {
|
||
|
|
* await delay(200)
|
||
|
|
*
|
||
|
|
* return 2
|
||
|
|
* },
|
||
|
|
* async () => {
|
||
|
|
* await delay(100)
|
||
|
|
*
|
||
|
|
* return 3
|
||
|
|
* }
|
||
|
|
* ]
|
||
|
|
*
|
||
|
|
* const batchSize = 2
|
||
|
|
*
|
||
|
|
* const result = await all(parallelBatch(input, batchSize))
|
||
|
|
*
|
||
|
|
* console.info(result) // [1, 2, 3]
|
||
|
