Abstract

A method including obtaining an index message at both (a) an index updater for an index and (b) a subindex updater for a subindex. The method also can include updating, by the index updater, the index based on the index message. The method additionally can include determining, at the subindex updater, whether the index message is eligible for the subindex. The method further can include updating, by the subindex updater, the subindex based on the index message when the index message is eligible for the subindex. Other embodiments are described.

First claim

What is claimed is:

1 . A system comprising:
one or more processors; and one or more non-transitory computer-readable media storing computing instructions that, when executed on the one or more processors, cause the one or more processors to perform:
obtaining an index message at both (a) an index updater for an index and (b) a subindex updater for a subindex;
updating, by the index updater, the index based on the index message;
determining, at the subindex updater, whether the index message is eligible for the subindex; and
updating, by the subindex updater, the subindex based on the index message when the index message is eligible for the subindex.

2 . The system of claim 1 , wherein the computing instructions, when executed on the one or more processors, further cause the one or more processors to perform:
loading an eligibility dictionary within the subindex updater from an eligibility database.

3 . The system of claim 2 , wherein the eligibility dictionary is loaded when the subindex updater is started.

4 . The system of claim 2 , wherein the eligibility dictionary is loaded when the subindex updater is changed to read from a different message partition.

5 . The system of claim 1 , wherein determining whether the index message is eligible for the subindex further comprises:
determining whether the index message is eligible for the subindex based on an eligibility dictionary within the subindex updater.

6 . The system of claim 1 , wherein determining whether the index message is eligible for the subindex further comprises:
determining whether the index message comprises an eligibility change event for the subindex; and updating an eligibility dictionary within the subindex updater based on an eligibility database when the index message comprises the eligibility change event for the subindex.

7 . The system of claim 6 , wherein the index message is generated by a data processor that receives notice of the eligibility change event after the eligibility database is updated:

8 . The system of claim 6 , wherein updating the subindex further comprises:
determining whether an item associated with the index message is eligible in the eligibility dictionary, as updated, when the index message comprises the eligibility change event for the subindex.

9 . The system of claim 8 , wherein updating the subindex further comprises:
adding the item to the subindex based on data for the item in the index message when the item is eligible.

10 . The system of claim 8 , wherein, updating the subindex further comprises:
deleting the item from the subindex when the item is not eligible.

11 . A method implemented via execution of computing instructions configured to run at one or more processors, the method comprising:
obtaining an index message at both (a) an index updater for an index and (b) a subindex updater for a subindex; updating, by the index updater, the index based on the index message; determining, at the subindex updater, whether the index message is eligible for the subindex; and updating, by the subindex updater, the subindex based on the index message when the index message is eligible for the subindex.

12 . The method of claim 11 further comprising:
loading an eligibility dictionary within the subindex updater from an eligibility database.

13 . The method of claim 12 , wherein the eligibility dictionary is loaded when the subindex updater is started.

14 . The method of claim 12 , wherein the eligibility dictionary is loaded when the subindex updater is changed to read from a different message partition.

15 . The method of claim 11 , wherein determining whether the index message is eligible for the subindex further comprises:
determining whether the index message is eligible for the subindex based on an eligibility dictionary within the subindex updater.

16 . The method of claim 11 , wherein determining whether the index message is eligible for the subindex further comprises:
determining whether the index message comprises an eligibility change event for the subindex; and updating an eligibility dictionary within the subindex updater based on an eligibility database when the index message comprises the eligibility change event for the subindex.

17 . The method of claim 16 , wherein the index message is generated by a data processor that receives notice of the eligibility change event after the eligibility database is updated:

18 . The method of claim 16 , wherein updating the subindex further comprises:
determining whether an item associated with the index message is eligible in the eligibility dictionary, as updated, when the index message comprises the eligibility change event for the subindex.

19 . The method of claim 18 , wherein updating the subindex further comprises:
adding the item to the subindex based on data for the item in the index message when the item is eligible.

20 . The method of claim 18 , wherein, updating the subindex further comprises:
deleting the item from the subindex when the item is not eligible.
