composing dataloaders

Hi,

I have a datafetcher where I use 2 dataloaders in sequence: the first to translate from 1 ID to another, the second to fetch data corresponding to the second ID.

loader1.load(id1).thenCompose(id2 -> loader2.load(id2))

This hangs because dispatchAll() is not called again after loader1 completes.
I can work around that by adding that call inside the thenCompose() lambda but then it is called for every id2 which is ugly at the very least.

Is there a better way of doing this?

未指定來源檔案或測試。先追蹤循序 loader 範例 loader1.load(id1).thenCompose(...) 中 dispatchAll 的生命週期，然後檢查巢狀 load 預期應如何進行 dispatch。完成的標準是循序 dataloader 能在不掛起的情況下完成，且 batching 不需要針對每個 id 呼叫 dispatch。
