Abstract: The technology disclosed relates to discovering multiple previously unknown and undetected technical problems in fault tolerance and data recovery mechanisms of modern stream processing systems. In addition, it relates to providing technical solutions to these previously unknown and undetected problems. In particular, the technology disclosed relates to discovering the problem of modification of batch size of a given batch during its replay after a processing failure. This problem results in over-count when the input during replay is not a superset of the input fed at the original play. Further, the technology disclosed discovers the problem of inaccurate counter updates in replay schemes of modern stream processing systems when one or more keys disappear between a batch's first play and its replay. This problem is exacerbated when data in batches is merged or mapped with data from an external data store.

The disclosed systems and methods for adding and customizing quick actions make it possible for developers, admins, and ISVs to provide customized actionable visual data representations with direct linking for accessing data in a company's records and for linking to third party sites, without saving a new state on a server when dashboard elements are updated.

Abstract: The technology disclosed relates to managing processing of long tail task sequences in a stream processing framework. In particular, it relates to operating a computing grid that includes a plurality of physical threads which processes data from one or more near real-time (NRT) data streams for multiple task sequences, and queuing data from the NRT data streams as batches in multiple pipelines using a grid-coordinator that controls dispatch of the batches to the physical threads. The method also includes assigning a priority-level to each of the pipelines using a grid-scheduler, wherein the grid-scheduler initiates execution of a first number of batches from a first pipeline before execution of a second number of batches from a second pipeline, responsive to respective priority levels of the first and second pipelines.

Abstract: The technology disclosed relates to maintaining throughput of a stream processing framework while increasing processing load. In particular, it relates to defining a container over at least one worker node that has a plurality workers, with one worker utilizing a whole core within a worker node, and queuing data from one or more incoming near real-time (NRT) data streams in multiple pipelines that run in the container and have connections to at least one common resource external to the container. It further relates to concurrently executing the pipelines at a number of workers as batches, and limiting simultaneous connections to the common resource to the number of workers by providing a shared connection to a set of batches running on a same worker regardless of the pipelines to which the batches in the set belong.

Further, data structures, which record monitoring status of particular IoT devices, are compiled. Finally, the state processing network further selects an alternative action to trigger, and triggers the selected action using at least some data from a particular event being processed.

Abstract: The technology disclosed relates to managing resource allocation to task sequences in a stream processing framework. In particular, it relates to operating a computing grid that includes machine resources, with heterogeneous containers defined over whole machines and some containers including multiple machines. It also includes initially allocating multiple machines to a first container, initially allocating first set of stateful task sequences to the first container, running the first set of stateful task sequences as multiplexed units of work under control of a container-scheduler, where each unit of work for a first task sequence runs to completion on first machine resources in the first container, unless it overruns a time-out, before a next unit of work for a second task sequence runs multiplexed on the first machine resources. It further includes automatically modifying a number of machine resources and/or a number assigned task sequences to a container.

Abstract: Techniques for providing feed-based case management on an online social network. A user interface that includes a publisher and an information feed is provided. Information associated with a record is received and the record is updated in a database system. A feed item associated with the database system update is generated and provided in the information feed. The feed item includes one or more actionable selections providing a reference to the publisher. Selection of one of the one or more actionable selections causes the publisher to be operable to receive further information associated with the record. The record is capable of being updated based on the further information. In some implementations, the record is a case and the user interface serves as a single interface for all interactions required in solving the case.

Drop-down menu items are particularly useful for assisting a user with assigning information synchronized into a target database from one database system, such as an Outlook file, to objects in the target database system, such as a multi-tenant database system as well as providing suggestions to the user from search results when they may want to choose one of those results or perform a different action altogether.

Abstract: A predicate-based row level security system is used when workers build or split an analytical data store. According to one implementation, predicate-based means that security requirements of source transactional systems can be used as predicates to a rule base that generates one or more security tokens, which are associated with each row as attributes of a dimension. Similarly, when an analytic data store is to be split, build job, user and session attributes can be used to generate complementary security tokens that are compared to security tokens of selected rows. Efficient indexing of a security tokens dimension makes it efficient to qualify row retrieval based on security criteria.

Abstract: Computer-implemented methods and systems are provided for writing events to a data store. An application server generates events, the data store that stores the events, and a temporary events file storage system (TEFSS) temporarily stores groups of events as events files. When events are unable to be written directly to the data store, an indirect events writer is invoked that includes event capture threads each being configured to generate a particular events file, and write it to the TEFSS. Each events file includes a plurality of events flushed from an in-memory buffer service. An events file uploader service reads the events file(s) from the TEFSS, and then writes the events from each of the events files to the data store.

The user system includes a processing system, memory and an input system that receives input parameters specified by a user of the user system. The memory can store a source class filter module executable by the processing system. Upon being executed by the processing system, the source class filter module can, based on one or more of the input parameters, group and filter source class identifiers to generate a unique source class identifier array of filtered source class identifiers that correspond to a particular subset of source classes that targeted code coverage metrics are to be computed for during code coverage computations when testing an application.

Abstract: Computer-implemented methods and systems are provided. The system includes a data store that is configured to store events in an event table, a temporary events file storage system (TEFSS), and a cluster of application servers. The cluster includes a first application server that generates events, and a second application server that includes an events file uploader service. When the first application server is unable to directly write events to the data store, an indirect events writer generates events file(s), and writes the events file(s) to the TEFSS. Each events file includes a plurality of events flushed from an in-memory buffer service at the first application server. When the events file uploader service determines that the first application server is inactive, it reads the events file(s) from the TEFSS, and writes the events from each of the events files to the data store.
