Abstract: Here is database replication that, for consistency and security, is based on an innovative unidirectional gateway that modifies and annotates a sequence of human-readable database transaction files. On a communication network, the unidirectional gateway receives a batch of change entries in a database transaction extensible markup language (XML) file. The unidirectional gateway modifies change entry(s). The unidirectional gateway generates and inserts, into the database transaction XML file, metadata that describes the modifications of the change entries. The modified database transaction XML file is converted into a binary file format that for a downstream database and, before or after that conversion, downstream processing of the database transaction file is based on the metadata that describes the modifications of the change entries.

Abstract: Techniques for implementing an orchestration service for data replication are provided. In one technique, a recipe is stored that comprises (1) a set of configuration parameters and (2) executable logic, for a data replication operation, that comprises multiple sub-steps. Each sub-step corresponds to one or more configuration parameters in the set of configuration parameters, which includes a first parameter that is associated with a default value and a second parameter that is not so associated. User input that specifies a value for the second parameter is received. The set of configuration parameters is updated to associate the value with the second parameter. The data replication operation is then initiated by processing the executable logic, which processing comprises, for each sub-step of one or more sub-steps, making an API call to a data replication service. In response to each API call, a response is received from the data replication service.
