Asynchronous setup settings

[Tobie Morgan Hitchcock]

Hi,

I was wondering what the difference is between the following settings in the default-distributed-db-config.json file:

{

    "executionMode": "undefined",

    "readQuorum": 1,

    "writeQuorum": 1,

}

or

{

    "executionMode": "asynchronous",

    "readQuorum": 1,

    "writeQuorum": 2,

}

Obviously they will both return immediately after writing to each local node (instead of waiting for other nodes in the quorum) but are there any other differences?

Thanks!

Yes in async mode the quorum still has to be reached, so if the quorum is not reached your value is overriden.

So depending on your setup both write but have no guarantee that it will stay written.
