How to make job execution faster?

Hello,

I am running a migration job with the attached design, and it is taking a whole day to complete.

Is there any way to shorten the execution time?

I have tried to execute the subjob which has “row1” in parallel following this guide (https://help.talend.com/r/en-US/8.0/studio-user-guide/executing-multiple-subjobs-in-parallel), but I have been failing.

Thanks in advance,

Hi

The performance depends on how many tables you need to migrate and the data volume of each table. This is a simple Job, I don't think we have much to optimize, one point I suggest is to commit the change for each iteration after tOracleOutput.

...tOracleOutput--oncomponentok--tDBCommit

|onsubjobok

tOracleClose1...

 

What is the error if you enable parallel execution on iteration (after tjavaFlex_3)?

 

Regards

Shong
