Abstract: A distributed shared log storage system employs an adapter that translates APIs for a big data application to APIs of the distributed shared log storage system. An instance of an adapter is configured for different big data applications in accordance with a profile thereof, so that the big data applications can take on a variety of added characteristics to enhance the application and/or to improve the performance of the application. Included in the added characteristics are global or local ordering of operations, replication of operations according to different replication models, making the operations atomic and caching.

Abstract: Certain embodiments described herein are directed to methods and systems for adding one or more nodes to a first cluster including a first node in a computer system. A method performed by the first node comprises receiving a first request from a second node to join the first cluster. The method also comprises retrieving a first cluster configuration associated with the first cluster from a distributed database through a first database server (DBS) and creating a second cluster configuration using the first cluster configuration and information received from the second node as part of the request. The method further comprises populating a first one or more local trust stores of a first one or more processes executing on the first node with a second one or more security certificates of a second one or more processes executing on the second node. The method further comprises writing the second cluster configuration to the distributed database and returning the second cluster configuration to the second node.

Abstract: Certain aspects described herein are directed to methods and systems for updating a status of a first process. In certain aspects, a method includes periodically examining a first table stored in a consistent and distributed database, wherein the table includes a first indication of a status of the first process and a second indication of a status of a second process and the first process and the second process are clustered for implementing functions of a distributed application in a distributed manner. The method further includes determining that the first indication has not changed during a first time period and changing the status of the first process in a second table to reflect that the first process is non-operational, wherein a different share of workload associated with the distributed application is performed by the second process as compared to when the first process was operational.

Abstract: Virtualized computing instances, such as virtual machines, in a virtualized computing environment are provisioned using a tree-based template structure. The tree-based template structure includes a base node and multiple nodes linked to the base node. Each of the multiple nodes includes at least one component that represents a delta relative to the base node. By matching the requirements and role of a virtualized computing instance to be provisioned with the content(s) of a particular node, the particular node can be selected for cloning/creating the virtualized computing instance.

Abstract: A distributed shared log storage system employs an adapter that translates APIs for a big data application to APIs of the distributed shared log storage system. The adapter is configured for different big data applications in accordance with a profile thereof, so that storage performance using the distributed shared log storage system can be comparable to the storage performance of the profiled big data application. An over-utilized adapter instance is detected and the workload assigned to the over-utilized adapter instance is either moved to a different adapter instance that can handle the workload or split among two or more adapter instances.
