Description

Event Publisher Module for In-memory Hash Map
In this invention we have an In-memory Hash Map (or Hash Map in main memory of the system) where key- value pairs of objects can be added, updated and deleted at any time. Here we have an Event Publisher module in the Hash Map which is invoked when a key-value pair of objects in the Hash Map gets added, updated or deleted. Event Publisher module maintains a list of subscribers for all kinds of events like addition, update or deletion on different entries in the Hash Map and pushes the key- value pair of objects for the entry in the Hash Map which got inserted, updated or deleted to the list of subscribers subscribed with the Event Publisher module for insertion, update or deletion events respectively. Event Publisher Module maintains a Look Up Table with event like insertion, update or delete as the key and value as list of subscribers for the event. Also here different Hash Map entries might have expiry timers or Time To Live (TTL) which on expiry invoke the Event Publisher Module to publish to a list of subscribers expiry or delete event for the key- value pair of objects expired or getting deleted.

Claims

Claims Following is the claim for this invention: -
1 . In this invention we have an In-memory Hash Map (or Hash Map in main memory of the system) where key- value pairs of objects can be added, updated and deleted at any time. Here we have an Event Publisher module in the Hash Map which is invoked when a key-value pair of objects in the Hash Map gets added, updated or deleted. Event Publisher module maintains a list of subscribers for all kinds of events like addition, update or deletion on different entries in the Hash Map and pushes the key- value pair of objects for the entry in the Hash Map which got inserted, updated or deleted to the list of subscribers subscribed with the Event Publisher module for insertion, update or deletion events respectively. Event Publisher Module maintains a Look Up Table with event like insertion, update or delete as the key and value as list of subscribers for the event. Also here different Hash Map entries might have expiry timers or Time To Live (TTL) which on expiry invoke the Event Publisher Module to publish to a list of subscribers expiry or delete event for the key- value pair of objects expired or getting deleted. The above novel technique of providing Event Publisher Module for various kinds of operations like insertion, update or deletion on the Hash Map is the claim for this invention.
