Abstract
Official abstract text for this publication.
A system and method for database migration is provided. In an example embodiment, the database migration technique may include a first connection to a relational database, a second connection to an in-memory database, and a migration framework to analyze the data structures of the relational database so as to identify first and second subsets of data structures. The first subset of data structures is migrated to the in-memory database during an uptime period of the relational database, and the second subset of data structures is migrated to the in-memory database during a downtime period of the relational database.
First claim
Opening claim text (preview).
We claim: 1 . A database migration system, comprising: one or more processors; and memory storing a plurality of integrated programs for execution by the one or more processors, one of the plurality of integrated programs including: a first connection to a relational database; a second connection to an in-memory database; a migration framework to analyze the data structures of the relational database so as to identify first and second subsets of data structures, wherein the first subset of data structures is migrated to the in-memory database during an uptime period of the relational database, and the second subset of data structures is migrated to the in-memory database during a downtime period of the relational database. 2 . The database migration system of claim 1 , wherein each of the first subset of data structures has a size that exceeds a predetermined threshold. 3 . The database migration system of claim 1 , wherein each of the first subset of data structures has a number of entries that exceeds a predetermined threshold. 4 . The database migration system of claim 1 , wherein each of the first subset of data structures has a calculated criticality indicator that exceeds a predetermined threshold. 5 . The database migration system of claim 1 , wherein the migration framework includes a shadow relational database. 6 . The database migration system of claim 1 , wherein the migration framework includes a shadow in-memory database. 7 . The database migration system of claim 1 , wherein the migration framework consolidates multiple relational databases into a single in-memory database. 8 . A method for database migration, comprising: connecting to a relational database; connecting to an in-memory database; providing a migration framework to analyze the data structures of the relational database so as to identify first and second subsets of data structures, wherein the first subset of data structures is migrated to the in-memory database during an uptime period of the relational database, and the second subset of data structures is migrated to the in-memory database during a downtime period of the relational database. 9 . The method for database migration of claim 8 , wherein each of the first subset of data structures has a size that exceeds a predetermined threshold. 10 . The method for database migration of claim 8 , wherein each of the first subset of data structures has a number of entries that exceeds a predetermined threshold. 11 . The method for database migration of claim 8 , wherein each of the first subset of data structures has a calculated criticality indicator that exceeds a predetermined threshold. 12 . The method for database migration of claim 8 , wherein the migration framework includes a shadow relational database. 13 . The method for database migration of claim 8 , wherein the migration framework includes a shadow in-memory database. 14 . The method for database migration of claim 8 , wherein the migration framework consolidates multiple relational databases into one in-memory database. 15 . A non-transitory computer readable storage medium storing one or more programs configured to be executed by a processor, the one or more programs comprising instructions for: connecting to a relational database; connecting to an in-memory database; providing a migration framework to analyze the data structures of the relational database so as to identify first and second subsets of data structures, wherein the first subset of data structures is migrated to the in-memory database during an uptime period of the relational database, and the second subset of data structures is migrated to the in-memory database during a downtime period of the relational database. 16 . The computer readable storage medium of claim 15 , wherein each of the first subset of data structures has a size that exceeds a predetermined threshold. 17 . The computer readable storage medium of claim 15 , wherein each of the first subset of data structures has a number of entries that exceeds a predetermined threshold. 18 . The computer readable storage medium of claim 15 , wherein each of the first subset of data structures has a calculated criticality indicator that exceeds a predetermined threshold. 19 . The computer readable storage medium of claim 15 , wherein the migration framework includes a shadow relational database. 20 . The computer readable storage medium of claim 15 , wherein the migration framework includes a shadow in-memory database. 21 . The computer readable storage medium of claim 15 , wherein the migration framework consolidates multiple relational databases into one in-memory database.
