[question] how stable is transaction implementation? #19

Closed mvayngrib closed 7 years ago

mvayngrib commented 7 years ago

i realize this library isn't maintained anymore, but how stable/mature is the transaction support?

aaaristo commented 7 years ago

It is a way outdated. And it is an experiment. It never left alpha stage.

@aaaristo hey, thanks for getting back to me. Do you know of a more mature JS dynamodb transactions implementation?

aaaristo commented 7 years ago

Unfortunately not, but nowadays with babel and async/ await copying the java one should be a breeze.

@aaaristo i see, thanks. How significant was the performance drop? For example two puts in one transaction vs two puts in parallel?

aaaristo commented 7 years ago

As far as I recall, it was 7 writes more for each write. But it should be better described in the dynamo-transactions java project. Still each block of writes can happen in parallel.

Please refer to: https://github.com/awslabs/dynamodb-transactions/blob/master/DESIGN.md
