A write lock request for a data object on behalf of a first data accessor is received at a lock manager. The data object is currently locked on behalf of a second data accessor. The lock manager modifies lock metadata associated with the data object to indicate the first data accessor as the primary lock owner, and designates the second data accessor as a non-primary owner.

Customizable lock management for distributed resources

The present disclosure provides a method and system for a scalable complex event processing of event streams. The method includes reception of one or more input event streams and collection of one or more output event streams. Further, the method includes modeling of each instance of each input event stream and each instance of the plurality of instances for intermediate states as records of a database table. The method includes indexing of each record of the database table and distribution of a first set of records in temporary memory and the second set of records in one or more persistent storage devices. The method includes flushing the second set of records of the database table in one or more persistent storage devices and querying of the plurality of records of the database table. The method includes inferring one or more complex events from transition of a plurality of states.

Methods, systems, and computer-readable media for live migration for highly available data stores are disclosed. Migration of a data set from a first data store to a second data store is initiated and comprises a backfill of records to the second data store. During a window of time before the migration is complete, a read request for a first record is received. A response representing an authoritative version of the first record is generated using a copy of the first record in the first data store and a copy of the first record in the second data store. A write request for a second record is received during the window of time. A lock is acquired for the second record, and the write request is performed using a copy of the second record in the first data store and a copy of the second record in the second data store.
