Abstract
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.
