Summary log

This contains a high-level overview of the conversion.

Error log

This contains a simple list of all errors, grouped by table.

Conversion summary

Basic statistics and information about conversion.

SQL statements

A complete list of all SQL statements sent to the target database. When target database is not relational, this log will be empty. When bulk mode is used, there will be no SQL INSERT statements, because bulk mode bypasses SQL to achieve maximal performance. If you absolutely need to have those statements, force single SQL insert mode. That will be very slow, but is very good for troubleshooting and inspection of data.

SQL errors statements

Only SQL statements that caused target database to report an error are saved here. Whenever you get some error not related to data, this is the place to look.

JSON log

The richest log. As JSON is structured and hierarchical, we store a lot information in here:

  • - high-level overview
  • - performance details for each table
  • - errors
