    Abstract: A computer-implemented method comprises creating and storing a plurality of different access group identifiers each associated with one or more user account identifiers, and a plurality of different classification markings each representing a different access restriction for an electronic document, and associating each of the user account identifiers with one or more of the classification markings; indexing each particular electronic document among a plurality of different electronic documents in association with values of one or more of the access group identifiers and with an inverse list of values of the classification markings that apply to the particular electronic document in a classification index; receiving a search query that specifies one or more attributes of electronic documents; obtaining one or more first classification markings, among the plurality of classification markings, which are associated with a particular user account identifier that is associated with the search query; executing a search of the classification index based on the search query using a covering query that requires a specified minimum number of matches between the one or more first classification markings and one or more second classification markings that are associated with a particular electronic document, and adding the particular electronic document to a result set of the search only when the covering query is satisfied; providing the result set in response to the search query.

    Abstract: 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.

    Abstract: Systems and methods are provided for master-to-master OT-based artifact peering. A “master-to-master” architecture for artifacts is implemented in a network comprising a plurality of nodes and clients, where no node is designated a “master” or “primary” for a given artifact. A first node receives a subset of remote proposed operations from a second node and determines if a conflict exists between the received subset of remote proposed operations and at least one of a plurality of locally-proposed operations. The first node resolves the conflict based on a total-ordering agreed upon between the first node and the second node. The first node transforms at least one operation, either received or locally-proposed, based on the resolved conflict. The first node than updates a local log to include the transformed operation.

    Abstract: Systems and methods are provided in order to avoid ingesting the entire contents of one or more data sources. An object may be associated with one or more pieces/fragments of data that can be stored in different data sources. When a request for the object is initiated, a search for those pieces/fragments of data can be performed. Nodes associated with each data source may generate data queries appropriate for its corresponding data source, retrieve, and if needed transform the data into an object-based data structure. Any pieces/fragments of data that have been discovered and retrieved can be joined, e.g., by an application programming interface server, and forwarded to a requesting client or application. In this way, only data relevant to the object is obtained. Moreover, object versioning can be employed so that the most up-to-date data is obtained.

    Abstract: Systems, methods, and non-transitory computer readable media are provided for using linked documents. A system may receive, from a computing device, a request for a document. Content of the document may be defined based on state information and stateless information. A system may determine a local replica of the document in a local database. The local replica of the document may be linked to a primary replica of the document. The local replica of the document may include a snapshot of the primary replica of the document. The primary replica of the document may be stored in a remote database which may be accessible through a remote server. The system may subscribe to the primary replica of the document through the remote server, and may provide access to the document to the computing device based at least in part on the subscription to the primary replica of the document.
