Methods and apparatuses are described for synchronization of metadata between databases in a cloud computing environment. A computing device identifies jobs that synchronize metadata from a first database instance to a second database instance, each job comprising synchronization tasks for a different portion of the metadata. The computing device determines a count of the synchronization tasks for each job. The computing device allocates each job to a first queue where the count of the synchronization tasks for the job is below a threshold value, and allocates the synchronization tasks for each job to a second queue where the count of the synchronization tasks for the job is at or above the threshold value. The computing device executes the jobs in the first queue and executes the synchronization tasks in the second queue to synchronize the corresponding metadata to the second database instance.
