Abstract: In one respect, there is provided a distributed database system. The distributed database system can include a plurality of nodes. A first node of the plurality of nodes can be configured to: group the plurality of nodes into at least a first cluster; select a second node to act as a gateway node for the first cluster; determine that at least one recipient node of a message is included in the first cluster; and route the message to the recipient node by at least sending the message to the second node. Related methods and articles of manufacture are also disclosed.

Abstract: A system and method to receive a replicated representation of a data entity and a replicated representation of application specific permissions associated with the data entity, the application specific permissions being defined by a source application sourcing the data entity; store the replicated representations of the data entity and the application specific permissions in a dedicated storage space for the source application within a consolidated cloud storage; automatically generate a secured data entity based on an integration of the replicated representation of the application specific permissions with the replicated representation of the data entity; and store the generated secured data entity in the dedicated storage space for the source application.

Abstract: A distributed database system can include a plurality of nodes. In order to execute a query at the distributed database system, one or more of the plurality of nodes can perform operations included in an execution plan for the query. A first node of the plurality of nodes can group the plurality of nodes into at least a first cluster. The first node can further select a second node to act as a gateway node for the first cluster. The first node can determine that at least one recipient node of a message is included in the first cluster and route the message to the recipient node by at least sending the message to the second node. Related methods and articles of manufacture are also disclosed.

Abstract: A system, a method, and a computer program product for scalable processes for write-order preserving data stream consumption. A data partition in a plurality of data partitions of data stream is selected based on a request received from a client processing node. The plurality of data partitions are distributed among a plurality of broker nodes in a distributed messaging system. A broker node in the plurality of broker nodes hosting the selected data partition is identified. The identified broker node provides the selected data partition to the client processing node for performing at least one function.

Abstract: In one respect, there is provided a distributed database system. The distributed database system can include a plurality of nodes and a plurality of optimizers. A first optimizer of the plurality of optimizers can be configured to: receive, from a client, a command; generate, based at least in part on global metadata cached by the first optimizer, an execution plan for fulfilling the command that includes one or more tasks to be performed by at least a first node of the plurality of nodes; determine that at least one task of the one or more tasks are not successfully performed by the first node; and in response to determining that at least one task of the one or more tasks are not successfully performed by the first node, updating the cached global metadata at the first optimizer.

Abstract: In one respect, there is provided a distributed database system that includes a first local scheduler node and a second local scheduler node. The first local scheduler node can be configured to coordinate a performance of a first task and a second task by a first worker node associated with the first local scheduler node. The second local scheduler node can be configured to respond to a defect at the first local scheduler node by at least: collecting, from the first worker node, a log indicating one or more tasks completed by the first worker node prior to the defect at the first local scheduler node; determining, based at least on the log, that the first worker node has completed the first task but not the second task; and coordinating a performance of the second task by the first worker node. Related methods and articles of manufacture are also provided.

Abstract: In one aspect, a computer-implemented method includes calculating cardinality differences and combined sizes for one or more data block pairs in a relational database. The method also includes selecting a data block pair from the one or more data block pairs based on a calculated cardinality difference and a calculated combined size associated with the selected data block pair. The method further includes merging the selected data block pair to form a merged data block, and replacing the selected data block pair in the relational database by the merged data block.
