    Abstract: A low latency query engine for APACHE HADOOP™ that provides real-time or near real-time, ad hoc query capability, while completing batch-processing of MapReduce. In one embodiment, the low latency query engine comprises a daemon that is installed on data nodes in a HADOOP™ cluster for handling query requests and all internal requests related to query execution. In a further embodiment, the low latency query engine comprises a daemon for providing name service and metadata distribution. The low latency query engine receives a query request via client, turns the request into collections of plan fragments and coordinates parallel and optimized execution of the plan fragments on remote daemons to generate results at a much faster speed than existing batch-oriented processing frameworks.

    Abstract: Embodiments of the present disclosure include systems and methods for encrypting a virtual machine image and accessing an encrypted virtual machine image. According to some embodiments an encryption module can encrypt a virtual machine image and place an encryption boot loader. The encryption boot loader may be extracted from the encrypted virtual machine image, be transmitted to, and stored at a key storage system. Upon a request to boot an operating system associated with the encrypted virtual machine image, a pre-boot execution environment may communicate with an image service to retrieve the encryption boot loader from the remote key storage system. The virtual machine image may therefore be decrypted suing the encryption boot loader, which may allow booting of the operating system.

    Abstract: Techniques are described for analyzing usage of data stored in a data storage system without accessing the stored data. In some embodiments, workload data indicative of queries executed at the data storage system on stored data is received. This workload data can include query logs generated during execution of the queries. The workload data is processed to identify data elements such as tables, columns, and views associated with the stored data as well as information regarding usage of the identified data elements. Usage can include operations performed on the data elements during execution of the queries. Based on this processing relationships between the identified data elements can be inferred and visualizations generated that convey information regarding usage of the data stored at the data storage system. Visualizations can include, among others, usage heatmap diagrams, join diagrams, column family diagrams, filter diagrams, view lineage diagrams, data flow diagrams, denormalization diagrams, and workload distribution diagrams.

    Abstract: Systems and methods of a memory allocation buffer to reduce heap fragmentation. In one embodiment, the memory allocation buffer structures a memory arena dedicated to a target region that is one of a plurality of regions in a server in a database cluster such as an HBase cluster. The memory area has a chunk size (e.g., 2 MB) and an offset pointer. Data objects in write requests targeted to the region are received and inserted to the memory arena at a location specified by the offset pointer. When the memory arena is filled, a new one is allocated. When a MemStore of the target region is flushed, the entire memory arenas for the target region are freed up. This reduces heap fragmentation that is responsible for long and/or frequent garbage collection pauses.
