Re: [jira] [Created] (AMQ-4267) Huge tx-*.tmp file in the kahadb directory

[Steven Turner <st...@gmail.com>]

Hey little bit confused about this file...

So according to my understanding, "if we are using transacted session at
producer side, than messages are sent to the broker only after producer
commit the transactions." 
So if a producer is sending the messages and does not commit at all, No
messages will be received by broker"


Now I am confused that How this tx-*.tmp file is getting created. If I am
using transactions of more than 'maxTransactionSize' than this tmp file is
created before commit. But As I was saying previously that messages are not
even received by broker before commit happens..

Please tell me exactly when this file is created ??

So basically this file is getting created, because Producer is using
transactions and has sent messages more than maxTransactionSize before
commit occurs.

and this file will only be created when I am using transactions ? 

Please correct me if I am wrong. 


Thanks

The messages are sent to the broker, just not dispatched until the 
commit occurs, we don't cache them on the client since you have no why 
of knowing how many would be sent so memory issues could occur, just to 
name one reason.

Steven has a point...

A message is not send to the broker untill commit occurs, SO how does this
tx-..tmp file gets created before commit ? 

Please explain this issue.. What is the root cause for this file creation... 

Thanks,
Sophia
