METHOD AND APPARATUS FOR THE STORAGE AND RETRIEVAL OF TIME STAMPED BLOCKS OF DATA
Embodiments disclosed herein provide systems, methods, and computer readable storage media for time-based storage and retrieval of data items. In a particular embodiment, a method provides receiving a point-in-time data request. Using metadata associated with data items stored in a secondary data repository, the method provides determining a mapping between the point-in-time data request and one or more of the data items. The method further includes providing the one or more data items in response to the point-in-time data request.
1 . A method of operating a data processing system for time-based storage and retrieval of data items, the method comprising:
receiving a point-in-time data request;
using metadata associated with data items stored in a secondary data repository, determining a mapping between the point-in-time data request and one or more of the data items; and
providing the one or more data items in response to the point-in-time data request.
2 . The method of claim 1 , further comprising:
receiving a request to perform an operation on the one or more data items;
performing the operation; and
providing results of the operation.
3 . The method of claim 2 , wherein the operation comprises a search and the request to perform the search is received from a user.
4 . The method of claim 2 , wherein the operation comprises an application process.
5 . The method of claim 2 , wherein the request to perform an operation includes the point-in-time data request.
6 . The method of claim 1 , further comprising:
identifying the data items in a primary data repository for storage in the secondary data repository;
generating the metadata indicating time information for the data items; and
storing the data items and the metadata in the secondary data repository.
7 . The method of claim 6 , wherein the time information includes a time when each of the data items was obtained from the primary data repository.
8 . The method of claim 6 , wherein determining a mapping between the point-in-time data request and one or more of the data items comprises:
using the time information to identify the one or more data items that satisfy the point-in-time data request.
9 . A data processing system for time-based storage and retrieval of data items, the data processing system comprising:
one or more computer readable storage media;
a processing system operatively coupled with the one or more computer readable storage media; and
program instructions stored on the one or more computer readable storage media that, when read and executed by the processing system, direct the processing system to;
receive a point-in-time data request;
using metadata associated with data items stored in a secondary data repository, determine a mapping between the point-in-time data request and one or more of the data items; and
provide the one or more data items in response to the point-in-time data request.
10 . The data processing system of claim 9 , wherein the program instructions further direct the processing system to:
receive a request to perform an operation on the one or more data items;
perform the operation; and
provide results of the operation.
11 . The data processing system of claim 10 , wherein the operation comprises a search and the request to perform the search is received from a user.
12 . The data processing system of claim 10 , wherein the operation comprises an application process.
13 . The data processing system of claim 10 , wherein the request to perform an operation includes the point-in-time data request.
14 . The data processing system of claim 9 , wherein the program instructions further direct the processing system to:
identify the data items in a primary data repository for storage in the secondary data repository;
generate the metadata indicating time information for the data items; and
store the data items and the metadata in the secondary data repository.
15 . The data processing system of claim 14 , wherein the time information includes a time when each of the data items was obtained from the primary data repository.
16 . The data processing system of claim 14 , wherein the program instructions that direct the processing system to determine a mapping between the point-in-time data request and one or more of the data items comprises program instructions that direct the processing system to:
use the time information to identify the one or more data items that satisfy the point-in-time data request.
