> I am hitting an issue with PutSQL processor which is pretty weird.
> What happen is, I have a 987 flow files sharing the same attributes
> [fragment.identifier], [fragment.count] and their respective [fragment.index]
> all stuck in upstream of PutSQL.
> In PutSQL, I have configured [Support Fragmented Transactions] to TRUE. If I
> understand correctly, when [Support Fragmented Transactions] is TRUE, PutSQL
> will wait till all the fragments arrive before executing the transaction, in
> which in my case, the fragment all arrived however the sql execution did not.
> Only when I restart PutSQL, then all the 987 flow files will get processed
> successfully right away.
> If I reconfigure [Transaction Timeout] to 5000ms, then the 987 flow files
> will flow to failure relationship after 5000ms. This I assume PutSQL is
> unable to detect that all the fragments has arrived upstream and push it to
> failure.
> The other thing I tried is that if I reconfigure [Support Fragmented
> Transactions] to FALSE, then the flow files will all get processed
> successfully right away.
> I am not entirely sure why PutSQL is behaving this way for fragmented
> transaction I was hoping someone could help me out on this.
