Federated search of multiple sources with conflict resolution

One or more non-transitory computer-readable media storing instructions which, when executed by one or more processors, causes performance of:

• automatically importing a plurality of changes to data in a plurality of data sources when the plurality of changes occur,
• wherein a first change is to first data in a first data source of the plurality of data sources,
• wherein a second change is to second data in a second data source, of the plurality of data sources, that is different than the first data source,
• wherein importing the plurality of changes comprising receiving, for each change of the plurality of changes, a push notification which is generated in response to said each change;
• in response to receiving a particular push notification that is associated with a particular change pertaining to a data object, (1) searching, based on one or more first search criteria, a repository for a repository data object associated with the particular change and (2) searching, based on one or more second search criteria, a data source for a data source data object associated with the particular change;
• inferring a change in a vector clock of the data object based on the particular change, wherein a first vector clock entry assigned to the repository data object has a first value and a second vector clock entry assigned to the data source data object has a second value;
• deconflicting the change in the vector clock based on data source rankings or repository rankings.

A method comprising:

• automatically importing a plurality of changes to data in a plurality of data sources when the plurality of changes occur,
• wherein a first change is to first data in a first data source of the plurality of data sources,
• wherein a second change is to second data in a second data source, of the plurality of data sources, that is different than the first data source,
• wherein importing the plurality of changes comprising receiving, for each change of the plurality of changes, a push notification which is generated in response to said each change;
• in response to receiving a particular push notification that is associated with a particular change pertaining to a data object, (1) searching, based on one or more first search criteria, a repository for a repository data object associated with the particular change and (2) searching, based on one or more second search criteria, a data source for a data source data object associated with the particular change;
• inferring a change in a vector clock of the data object based on the particular change, wherein a first vector clock entry assigned to the repository data object has a first value and a second vector clock entry assigned to the data source data object has a second value;
• deconflicting the change in the vector clock based on data source rankings or repository rankings.
