Adaptive edge processing of application data

A method of adaptively configuring a local data store at the edge of a network, said method comprising the steps of:

• identifying all combinations of network application database tables whose combined size can fit within space limitations of the local data store, and further identifying historically which combinations would have been able to best satisfy queries for application data;
• allocating enough space in said local data store to accommodate said combinations which are able to best satisfy said queries for application data and which further can fit within said space limitations of the local data store;
• and,
• further allocating at least a portion of said remaining space in said local data store for a data cache.

A method for processing a database query at the edge of a network, said method comprising the steps of:

• processing said database query in a database replication system, said database replication system determining whether said database query can be satisfied by replicated data stored in an allocated portion of a local data store, said database replication system satisfying said database query if it is determined that said database query can be satisfied by said replicated data;
• further processing said database query in a database caching system if it is determined that said database query cannot be satisfied by replicated data stored in an allocated portion of a local data store, said database caching system determining whether said database query can be satisfied by cached data stored in a second allocated portion of said local data store, said database caching system satisfying said database query if it is determined that said database query can be satisfied by said cached data;
• and,
• forwarding said database query to a back-end database system where it is determined that said database query can be satisfied neither by said database replication system nor by said database query system.

A machine readable storage having stored thereon a computer program for adaptively configuring a local data store at the edge of a network, said computer program comprising a routine set of instructions for causing the machine to perform the steps of:

• identifying all combinations of network application database tables whose combined size can fit within space limitations of the local data store, and further identifying historically which combinations would have been able to best satisfy queries for application data;
• allocating enough space in said local data store to accommodate said combinations which are able to best satisfy said queries for application data and which further can fit within said space limitations of the local data store;
• and,
• further allocating at least a portion of said remaining space in said local data store for a data cache.
