A method for updating a column store database and includes establishing a row store database, wherein each row comprises a plurality of attributes. The method includes establishing a column store database including attribute vectors corresponding to at least one attribute in the row store, wherein each attribute vector includes data used to satisfy at least one of previously received analytic queries. The method includes collecting a SQL change statements beginning from a synchronization point indicating when the row store database and the column store database are synchronized, and continuing until an analytic query is received. The method includes sending the plurality of SQL change statements to the column store database upon receipt of the analytic query for updating the column store database for purposes of satisfying the query, wherein the analytic query is directed to a queried range of primary key attributes in the plurality of attributes.

Statement based migration for adaptively building and updating a column store database from a row store database based on query demands using disparate database systems

A request to perform a transaction on a database in an online transaction processing system is accessed by a node. The sets of data in the database that the transaction is to act on are determined. The transaction is then separated into actions according to the data dependencies of the actions; an action is established for each set of data that is acted on by the transaction. The actions are communicated to the nodes that store the data that the respective actions depend on. The actions are then performed on the nodes to which they were routed.

Action-based routing of a transaction in an online transaction processing system

Various disclosed embodiments include methods and systems for managing lock or latch chains in concurrent execution of database queries. A method includes receiving a plurality of transactions, each transaction associated with one or more queuing requests. The method includes, for each transaction, determining one or more partition sets. Each partition set corresponds to one or more database partitions needed for the transaction. The one or more database partitions are included within a partitioned database. The method includes, for each transaction, determining one or more queues needed for the transaction and storing a bitmap representation of the one or more queues needed for the transaction. The one or more queues needed for the transaction correspond to the one or more database partitions needed for the transaction.
