A method for searching time series data over a network. The method comprises employing a computing device to gather at least one stream of time series data from an information processing environment and arrange the at least one stream of time series data for searching, wherein the computing device performs actions, including: aggregating data in the at least one time series data stream based on a domain that corresponds to the at least one time series data stream; time stamping the at least one time series data stream to generate at least one time stamped event that includes at least a portion of the aggregated data; segmenting each time stamped event into a plurality of segments; time indexing the time stamped events to create time bucketed indices based on the time stamps and segments; and employing the computing device to search the time bucketed indices based on a received time series data search request.

A system for managing allocation of resources based on service level agreements between application owners and cloud operators. Under some service level agreements, the cloud operator may have responsibility for managing allocation of resources to the software application and may manage the allocation such that the software application executes within an agreed performance level. Operating a cloud computing platform according to such a service level agreement may alleviate for the application owners the complexities of managing allocation of resources and may provide greater flexibility to cloud operators in managing their cloud computing platforms.

The system enables one to securely recycle an electronic device in a publicly accessible location. In particular, the embodiment described may be used by a mobile phone owner to submit his/her mobile phone for recycling via an electronic kiosk and receive compensation in some form. The compensation might be dispersed via cash, voucher, credit or debit card, or other magnetic or electronic transaction methods.

Complex data queries, because of their need for random accesses, have proven to be slow unless all the data can be accommodated in DRAM. There are many domains, such as genomics, geological data and daily twitter feeds where the datasets of interest are 5TB to 20 TB. For such a dataset, one would need a cluster with 100 servers, each with 128GB to 256GBs of DRAM, to accommodate all the data in DRAM. On the other hand, such datasets could be stored easily in the flash memory of a rack-sized cluster. Flash storage has much better random access performance than hard disks, which makes it desirable for analytics workloads. In this paper we present BlueDBM, a new system architecture which has flash-based storage with in-store processing capability and a low-latency high-throughput inter-controller network. We show that BlueDBM outperforms a flash-based system without these features by a factor of 10 for some important applications. While the performance of a ram-cloud system falls sharply even if only 5%~10% of the references are to the secondary storage, this sharp performance degradation is not an issue in BlueDBM. BlueDBM presents an attractive point in the cost-performance trade-off for Big Data analytics.

Network service operational status monitoring methods and apparatus are disclosed. Responsive to a service status request associated with a network service, an operational status of the network service is determined by an intermediary between a service status requester and the network service. The operational status is a service-specific operational status of the network service in some embodiments. Operational status may be determined through a multi-level procedure in which subsequent levels after a first level of the multi-level procedure are or are not performed depending on a result of a preceding level of the procedure. A multi-level procedure may involve a service connectivity check and a service operational check, for instance.

A method and system for anticipatory package shipping are disclosed. According to one embodiment, a method may include packaging one or more items as a package for eventual shipment to a delivery address, selecting a destination geographical area to which to ship the package, shipping the package to the destination geographical area without completely specifying the delivery address at time of shipment, and while the package is in transit, completely specifying the delivery address for the package.

Method and system for anticipatory package shipping

Techniques are described for facilitating a supply of used items on behalf of an entity that desires to acquire such used items, such as a merchant that sells used items to customers. The used items are obtained based on interactions with recipients who receive items that are sold or otherwise provided by one or more merchants (or other suppliers of items), such as by supplying appropriate information and materials to the recipients along with the items. In some situations, when an item is delivered or otherwise supplied to a recipient by a merchant, the merchant also supplies information to the recipient that indicates an offer from a used item acquirer entity to re-acquire the item from the recipient (such as after the recipient has used the item) and shipping materials for use in returning the item to an indicated destination if the recipient accepts the offer.

Facilitating a supply of used items

A computer-implemented data collection and analysis method comprises receiving from a client computing device, at least one data analysis datapoint, adding the received at least one data analysis datapoints to a data structure, and adding an additional data analysis datapoint to the data structure, storing, in a data repository, the data structure further comprising a data processing result, maintaining at least partially consistent copies of the data structure across the plurality of host computers, in response to a request regarding an operation from the client computing device, retrieving the data processing result from the data repository, and providing the data processing result using routing information to the client computing device. The data structure comprises an index of data analysis datapoints from the plurality of host computing devices. A portion of the additional data analysis datapoint is added to the data value to generate a data processing result.

Method and system for collecting and analyzing time-series data

In a system in which documents are generated dynamically in response to user requests, historical data is collected regarding data retrieval subtasks, such as service requests, that are performed to generate such documents. This data is used to predict the specific subtasks that will be performed to respond to specific document requests, such that these subtasks may be initiated preemptively at or near the outset of the associated document generation task. A subtask that would ordinarily be postponed pending the outcome of a prior subtask can thereby be performed in parallel with the prior subtask, reducing document generation times. In one embodiment, the historical data is included within, or is used to generate, a mapping table that maps document generation tasks (which may correspond to specific URLs) to the data retrieval subtasks that are frequently performed within such tasks.

Predictive prefetching to improve parallelization of document generation subtasks

A data processing system comprises web page generation logic and website experimentation logic. The web page generation logic is configured to generate web pages to be provided to visitors of a website. The website experimentation logic is coupled to the web page generation logic. The website experimentation logic is configured to detect a change in the manner in which the web page generation logic generates one or note of the web pages and to assess how the change impacts visitor interactions with the website.
