Disclosed herein are system, method, and computer program product embodiments for the auditable abrogation of columnar in-memory databases. An embodiment operates by retrieving column-oriented data of a column-oriented database associated with an auditing request to access the column-oriented data. The column-oriented data is transformed into corresponding row-oriented data and stored in a row-oriented database independent of the column-oriented database. A response to the auditing request is processed based on the row-oriented data, wherein the processing is performed independent of the column-oriented database, and the response is provided to the auditing request.
