Systems and methods for data propagation and mapping are provided. In an aspect, one or more data entries storing changed information in a first database using a first storage format are identified. The identified data entries are received by the data propagation and mapping system. The received data entries may be filtered to generate a subset of filtered data entries. The filtered data entries are transmitted to a mapping pipeline configured to map a data entry stored in the first storage format to a data entry stored in a second storage format. The mapped data entries are transmitted to a recipient second database storing data entries using the second storage format.
