A system synchronizes change-data in a multi-tenant system with one or more external service provider systems. The system comprises a system interface configured to receive transaction events; a write-optimized transactional database for recording the transaction events; a replicated read-optimized transactional database; a transaction log of change-data generated from the read-optimized transactional database; a first change-data processor configured to identify the change-data in the transaction log that is relevant to at least one external service provider system, and to generate an aggregate relevant change-data log; a second change-data processor configured to identify aggregate relevant change-data that is relevant to a particular external service provider system, and to generate a service provider relevant change-data log; a service provider connector configure to await a real-time trigger condition, and to, in response to the trigger condition, perform a synchronization session to synchronize the service provider relevant change-data with the particular external service provider system. |

1. A method of synchronizing change-data in a multi-tenant system with one or more external service provider systems, the method comprising:
receiving transaction events in a write-optimized transactional database of a multi-tenant system; replicating the transaction events in a read-optimized transactional database; generating a transaction log of change-data from the read-optimized transactional database; extracting, by a first change-data processor, the change-data from the transaction log; identifying, by the first change-data processor, the change-data in the transaction log that is relevant to at least one of one or more external service provider systems; generating an aggregate relevant change-data log; extracting, by a second change-data processor, the aggregate relevant change-data from the aggregate relevant change-data log, the second change-data processor being associated with a particular external service provider system of the one or more external service provider systems; identifying, by a second change-data processor, the change-data in the aggregate relevant change-data log that is relevant to the particular external service provider system; generating a service provider relevant change-data log; awaiting a trigger condition of one or more trigger conditions, at least one of the one or more trigger conditions including a real-time trigger condition; and in response to the trigger condition, performing a synchronization session to synchronize the service provider relevant change-data with the particular external service provider system. |
