The fetch* method of the cursor is synchronized? #86

Closed kamelzcs closed 9 years ago

kamelzcs commented 9 years ago

If it were true, is there anyway to do asynchronously?

kamelzcs commented 9 years ago

I found the cursor should have all the data inside it. when using the fetch method, there is no need to query the database anymore.

Isn't it?

Yes, all cursor data is buffered by client and you already have it when you resume from yield point.

Exception is the server-side (named) cursors. Their fetch operation requests data from server. That's why you need to yield their fetch operations in manual connection management mode.
