Abstract

A context-driven multi-user system may include distributed computing resource(s) that replicate proper subset(s) of user-relevant context data to computing device(s). A replication server may receive an update record corresponding to stored context data and determine propagation records based at least in part thereon. Each propagation record may correspond to a respective, different proper subset of the context data. The replication server may transmit the propagation records to respective replication clients. A replication client may receive a propagation record and modify local context data in response. The replication client may receive a data record and determine an update record in response and using the local context data. The computing device may transmit the determined update record. A server may receive a query specification referencing a data source and transmit the query specification to a replication client of the multi-user system, the client corresponding to the data source.

First claim

What is claimed is:

1. A method of replicating data using a replication server of a multi-user system, the method comprising:
storing context data on the replication server, the context data related to interaction(s) of one or more user(s) with or via the multi-user system, the context data comprising first information and second information;
receiving, from a first one of a plurality of replication clients of the multi-user system, an update record corresponding to less than all of the stored context data, wherein the update record corresponds to a request from a user for technical support, wherein the first information is related to a configuration of a computing device of the user, and wherein the second information identifies a support technician;
modifying the first information based at least in part on the update record, thereby producing modified first information;
modifying the second information based on the update record, thereby producing modified second information;
using the replication server, automatically determining a plurality of propagation records based at least in part on the update record, wherein the plurality of propagation records comprises:
a first propagation record that includes the modified first information and omits the modified second information; and
a second propagation record that includes the modified second information and omits the modified first information;

transmitting the first propagation record to a first propagation client; and
transmitting the second propagation record to a second propagation client.

2. The method of claim 1 , further comprising:
receiving, from a second one of the plurality of replication clients, a second update record corresponding to less than all of the stored context data;
using the replication server, automatically determining a plurality of second propagation records based at least in part on the received second update record, wherein each of the second propagation records corresponds to a respective, different proper subset of the stored context data; and
transmitting the plurality of second propagation records via one or more communications interfaces, wherein at least one of the propagation records and at least one of the second propagation records are transmitted to a selected one of the plurality of replication clients.

3. The method of claim 1 , further comprising:
determining a match between the update record and stored trigger conditions; and
in response to determining the match:
selecting data from the stored context data based at least in part on stored input criteria;
transmitting the selected data to an observer unit;
receiving a second update record from the observer unit; and
modifying the stored context data based at least in part on the received second update record.

4. The method of claim 3 , further comprising:
using the replication server, automatically determining a second plurality of propagation records based at least in part on the received second update record, wherein each propagation record corresponds to a respective, different proper subset of the stored context data; and
transmitting the propagation records of the second plurality of propagation records to respective ones of the replication clients via one or more communications interfaces.

5. The method of claim 3 , further comprising carrying out computer program instructions of the observer unit in a restricted-privilege execution configuration.

6. The method of claim 1 , further comprising:
determining a match between at least part of the stored context data and stored trigger conditions; and
in response to determining the match:
transmitting the at least part of the stored context data to an observer unit;
receiving a second update record from the observer unit; and
modifying the stored context data based at least in part on the received second update record.

7. The method of claim 1 , wherein:
receiving the updated record includes accepting data of the update record in response to a signal from the first one of the plurality of replication clients; and
transmitting the first propagation record and transmitting the second propagation record includes transmitting respective notification signals to respective ones of the replication clients.

8. The method of claim 1 , further comprising:
storing a snapshot of the stored context data separate from the stored context data;
processing the stored snapshot using a machine-learning algorithm, the machine-learning algorithm including a neural-network training algorithm; and
modifying the stored context data based at least in part on an output of the machine-learning algorithm.

9. The method of claim 1 , further comprising:
determining a match between stored trigger conditions and at least one of the update record, or at least part of the stored context data, and in response to determining the match:
selecting data from the stored context data based at least in part on stored input criteria;
providing the selected data to an observer unit;
determining whether the observer unit operates under security restrictions;
carrying out computer program instructions of the observer unit in a restricted privilege execution configuration to prevent unsigned plugins from executing based on a determination that the observer unit operates under security restrictions;
receiving a second update record from the observer unit based on a determination that the observer unit does not operate under security restrictions; and
modifying the stored context data based at least in part on the received second update record.

10. A system of replicating data using a replication server, the system comprising:
at least one processor;
memory in electronic communication with the at least one processor; and
instructions stored in the memory, the instructions being executable by the at least one processor to:
store context data on the replication server, the context data related to interaction(s) of one or more user(s) with or via the multi-user system, the context data comprising first information and second information;
receive, from a first one of a plurality of replication clients of the multi-user system, an update record corresponding to less than all of the stored context data, wherein the update record corresponds to a request from a user for technical support, wherein the first information is related to a configuration of a computing device of the user, and wherein the second information identifies a support technician;
modify the first information based at least in part on the update record, thereby producing modified first information;
modify the second information based at least in part on the update record, thereby producing modified second information;
using the replication server, automatically determine a plurality of propagation records based at least in part on the update record, wherein the plurality of propagation records comprises:
a first propagation record that includes the modified first information and omits the modified second information; and
a second propagation record that includes the modified second information and omits the modified first information;

transmit the first propagation record to a first propagation client; and
transmit the second propagation record to a second propagation client.

11. The system of claim 10 , further comprising instructions being executable by the at least one processor to:
receive, from a second one of the plurality of replication clients, a second update record corresponding to less than all of the stored context data;
using the replication server, automatically determine a plurality of second pr
