Traffic migration in a multilayered data service framework

A computer-implemented method for migrating requests for information about a plurality of customers stored in a legacy database to a partitioned data store having a plurality of partitions without interrupting access to the information, wherein the information is initially accessed through a first customer service server which is responsible for managing the legacy database, the computer-implemented method comprising:

• defining a plurality of buckets and associating the information about a plurality of customers with the plurality of buckets, wherein each bucket is associated with information about a distinct portion of the plurality of customers;
• deploying a second customer service server configured to access information about the plurality of customers, the second customer service server being in communication with a partitioning service which accesses the legacy database;
• receiving a request for accessing information about a customer at either the first customer service server or the second customer service server;
• establishing a plurality of partitions in the partitioned data store, wherein each partition is accessible by the partitioning service;
• upon establishing the plurality of partitions, for each bucket:
• copying information associated with the bucket to one of the plurality of partitions;
• updating, by a processor, a bucket to partition map to identify the partition to which the information associated with the bucket is contained;
• and
• allowing access to the information copied to one of the plurality of partitions through the partitioning service.
