    Default How to Improve performance of table output


    I am fetching the millians of records from source to Target
    Source -- oracle DB 12.1.3
    Target -- MySQL 5.5

    I am using table input step and table output step.
    input/output steps inserting 3 rows per sec.
    Can anybody give me suggestions, how to improve performance of input/output steps.

    That seems unusually slow. How wide are the rows? Are you dependent on a slow network?

    For further troubleshooting, try reading the source data from Oracle and dumping it to a local CSV file. Then try reading the local CSV file and writing it to MySQL. Those two tests might help isolate the bottleneck.
