Abstract: Different database deployments, or other data system deployments, may want to communicate with each other without sacrificing security or control. To this end, embodiments of the present disclosure may provide secure message exchange techniques for a source and/or target deployment. Configurable rule sets may be stored in the deployments; the rule sets may define what messages may be communicated between deployments. The deployments may implement a selective filtering scheme in one or more stages based on the rule sets to filter outgoing and/or incoming messages.

Abstract: A network device communication system can configure network devices (e.g., a primary and secondary database) to send and receive sequences messages, such as replication data, over a channel comprising a plurality of private network nodes. The messages can be generated and encrypted using one or more key pairs and changing wrapping replication keys to send and receive the messages between different types of database deployments.

Abstract: A networked device communication system can configure network devices (e.g., a primary and secondary database) to send and receive sequences of messages, such as replicated data, using one or more keypairs and wrapping keys. The sequences of messages can include an initial set of messages that are encrypted by a wrapping key, and further include another set of messages that are encrypted by a replaced staggered key. The sequence of messages can be configured to be decrypted without exporting keys of hardware security modules.

Abstract: Techniques for executing show commands are described herein. A plurality of navigation steps is utilized, each navigation step corresponding to a different layer in a database structure and each navigation step including an operator to fetch items from a metadata database up to respective bounded limits. Dependency information is also fetched for objects of the specified object type in the show command. After a set of objects from the last layer are processed, memory for the navigation steps is flushed and the next set of objects are processed.

Abstract: A system for data object replication includes at least one hardware processor and at least one memory storing instructions. The instructions cause the at least one hardware processor to perform operations including decoding a replication request to obtain a data object. Object dependencies associated with the data object and a plurality of additional data objects are determined. A replication sequence of the data object and the plurality of additional data objects is determined based on the object dependencies. A replication of the data object and at least one of the plurality of additional data objects is performed according to the replication sequence. A notification of a successful completion of the replication is generated.

Abstract: Provided herein are systems and methods for configuring replication of account object metadata. A system includes at least one hardware processor coupled to a memory and configured to decode a replication request received from a client device of a data provider. The replication request indicates at least a first account object, a source account, and a target account of the data provider. An object dependency of the at least first account object to at least a second account object of the data provider is determined. A replication of the at least first account object and the at least second account object is performed from the source account into the target account of the data provider.
