Limitations

The limitations mentionned below exists for now as fixing them will take time. But they can be overcome, and will be in due time!

HTTP calls

Currently HTTP calls are done via curl but it can't be integrated in the same loop as other streams. To allow the coordination of multiple tasks when doing HTTP calls the system use a timeout of 10ms and switches between tasks at this max rate.

To fix this limitation a new implementation entirely based on PHP streams needs to be created.

Meanwhile if your goal is to make multiple concurrent HTTP calls you don't need this package. innmind/http-transport already supports concurrent calls on it's own (without the limitation mentionned above).

SQL queries

SQL queries executed via $os->remote()->sql() are still executed synchronously (as it uses PDO).

To fix this limitation a new implementation entirely based on PHP streams needs to be created.

Scaling

It seems that the current implementation of this package has a limit of around 100K concurrent tasks before it starts slowing down.

A simple script scheduling 100k tasks that each halts the process for 10 second will take ~13s.
