txSize parameter in transaction

[Ariel Tubaltsev <tu...@gmail.com>]

Hi

I wanted to start the TX transaction with a timeout value, however the
"txStart" API also expects a "txSize" parameter. 

The documentation states we can pass an approximate value. 
https://ignite.apache.org/releases/latest/javadoc/org/apache/ignite/IgniteTransactions.html

Could you tell how to estimate it? It's just a number of different keys
participating in transaction.

In my application I am invoking the "getAndPutIfAbsent()" method twice (2
different caches) with 2 different keys. So what would need to be the
"txSize" ?

My use case - I just want to use timeout, I'd be happy to stick with any
default, if there is such thing.

Thank you
Ariel

Hello!

The default seems to be 0 so you can try and use that. I guess it's good
default unless your transaction is really large.
