Systems and methods including a framework for migration of live data. The method may comprised, by one or more hardware processors executing program instructions, receiving, at a migration proxy of the framework, code for reading data and writing data compatible with each of a plurality of states of a migration of data in a data store, wherein a service is at least intermittently reading data from and writing data to the data store; determining, by a migration runner of the framework, to perform the migration of the data; initiating, by the migration runner, the migration of the data, wherein the migration comprises a plurality of stages; storing, as the migration progresses through the plurality of stages, and at a migration data store of the framework, a current stage of the migration; and during the migration, using the migration proxy to read data from and write data to the data store.

Framework for live data migration

Systems and methods are provided for obtaining a request for a data object or a data structure from a client; determining an access level of the client and one or more access permissions of the requested data object or data structure; determining whether to transmit the requested data object or data structure to the client based on the access level of the client and the one or more access permissions; and transmitting the requested data object or data structure to the client.

Approaches of enforcing data security, compliance, and governance in shared infrastructures

Systems and methods are provided for adaptive data replication. A first data object is stored. One or more first network characteristics of a communication network are detected. A first replication mode is triggered (e.g., a single-master replication mode) based on the one or more first network characteristics of the communication network. The single-master replication may be configured to facilitate real-time synchronizations (e.g., for critical updates). One or more second network characteristics of the communication network are detected. A second replication mode (e.g., a multi-master replication mode) is triggered based on the one or more second network characteristics. The second replication may be configured to facilitate a delayed synchronization (e.g., for non-critical updates) of the first data object and the second data object using the second update file.

Systems and methods for adaptive data replication

Systems, methods, and non-transitory computer readable media are provided for security-aware caching of resources. An offline version of a resource may be prepared for a computing device. The offline version of the resource may include a security parameter. The security parameter may define a security rule to be enforced with respect to offline usage of the resource. The offline version of the resource may be provided for caching by the computing device. The cache of the offline version of the resource may enable the offline usage of the resource by the computing device. The security rule for the offline usage of the resource may be enforced by the computing device based on the security parameter.

Security-aware caching of resources

Systems and methods are provided for storing a first data object comprising a first set of immutable components, the first data object being associated with a corresponding second data object stored by a remote replication system. A difference is determined between the first set of immutable components of the first data object and a second set of immutable components of the corresponding second data object. A subset of immutable components is identified from the first set of immutable components based on the difference. The subset of immutable components from the first set of immutable components is provided to the remote replication system over a communication network.

Systems and methods for data replication synchronization

Methods and apparatuses related to federated search of multiple sources with conflict resolution are disclosed. A method may comprise obtaining a set of data ontologies (e.g., types, properties, and links) associated with a plurality of heterogeneous data sources; receiving a selection of a graph comprising a plurality of graph nodes connected by one or more graph edges; and transforming the graph into one or more search queries across the plurality of heterogeneous data sources. A method may comprise obtaining a first data object as a result of executing a first search query across a plurality of heterogeneous data sources; resolving, based on one or more resolution rules, at least the first data object with a repository data object; deduplicating data associated with at least the first data object and the repository data object prior to storing the deduplicated data in a repository that has a particular data model.

Federated search of multiple sources with conflict resolution

In an embodiment, a computer-implemented method comprises receiving a plurality of identifiers of first versions of electronic documents that have been stored in a distributed data storage system and queuing the identifiers in a queue table of a database; obtaining, from the queue table, a set of the identifiers of the first versions of the electronic documents; invoking, using the set of the identifiers, a query indexing function of a search engine system and receiving a set of matching identifiers of electronic documents, from among the set of identifiers, that match queries that have been registered using the query indexing function; storing the matching identifiers in a last-processed table; processing second versions of the electronic documents associated with the matching identifiers, using the query indexing function; updating a feed associated with a user account to show messages referring to the first versions of the electronic documents in response to determining that the second versions of the electronic documents do not match the queries.

Query indexing with permissions integration and federated search

Systems, methods, and non-transitory computer readable media are provided for using tiled data. An information request for an area may be received. Information for the area may be accessed. The information for the area may be stored in a tree structure such that the information is subdivided into one or more levels of tiles. Individual tiles may correspond to a portion of the area. One or more tiles may include precomputed information for the corresponding portion(s) of the area. A response to the information request may be determined based on the precomputed information.
