Abstract: Aspects of the current subject matter are directed to a user-facing approach for migration of unstructured data. A graphical user interface is provided to enable a user to execute a migration process of attachments between content repositories, where the execution is end to end with simple commands and/or user actions through interaction with the graphical user interface. The commands and/or user actions are translated into a background execution of the steps of the migration process in the proper order with proper parameters. Aspects of the current subject matter provide for the migration process to be transparent to the end user. Logs or reports relating to the migration process may be available and accessible to the user.

Abstract: A system for verifying data integrity in a database may include accessing a first file with a management object. The management object corresponds to a set of database tables located in a database. The system loads a data extract file including the management object, the data extract file containing fields related to content associated with the management object. The system accesses a second file with a condition, the condition being indicative of the content associated with the management object. The system generates code to evaluate the management object in the data extract file. The system evaluates the content associated with the management object in the data extract file using the generated code. The system identifies an entry in the data extract file that does not meet the condition, the entry representative of content associated with the management object, and then presents the entry to a user.

Abstract: A computer implemented method, system and computer program product are provided that implement a neural network (NN) audio filter. The method, system and computer program product obtain an electronic audio signal comprising a speech impaired message and apply the audio signal to the NN audio filter to modify the speech impaired message. The apply operation converts the audio signal into characters; and identifies and removes at least one of a repetitive pattern or duplicate word in the characters to form the unimpaired message. The unimpaired message is output.

Abstract: A system of nodes configured to form a network comprising virtual links in an overlay network provisioned over an underlay network including servers of a public network. The system includes virtual routers (VRs) at each node. Each VR is coupled to the network and to a tenant of the node, and configured to form in the network a set of virtual links corresponding to the tenant. One or more VRs includes a feedback control system comprising an objective function that characterizes the network. The VR is configured to receive link state data of the set of virtual links and control routing of a tenant traffic flow of each tenant according to a best route of the network determined by the objective function using the link state data.

Abstract: A method may include intercepting a database query from a client to a database. The database query may include a first identifier associated with a first database table. A second database table stored at the database may be determined to correspond to the first database table. The database query may be reconstructed by at least replacing the first identifier with a second identifier associated with the second database table. The reconstructed database query may be executed by at least sending, to the database, the reconstructed database query. Related systems and articles of manufacture, including computer program products, are also provided.
