Data races are resolved and rows are deduplicated between upqueries and updates to an underlying database, in a database caching layer on top of the underlying database. The caching layer maintains a dataflow graph of nodes representing row data of the underlying database, database operators, and partially or fully materialized queries, wherein queries that use common row data and/or database operators share corresponding nodes. A data race resolution and row deduplication algorithm may be applied on every node that contains a partial materialization, and is correct regardless of how many times this node is reused throughout the dataflow graph. It prevents any of the nodes from seeing duplicated packets between the external upqueries that are originated from each node and any underlying database change events which the node observes. It does so by tagging the records in change events with unique identifiers for the paths in the graph that have seen them before, and by delaying any of the change events that could conflict with any existing in-flight external upqueries.

A branch of a main database is created, comprising a copy of the main database schema. A user edits the branch and requests that it be merged back into the main database. A schema diff is generated and used to determine differences between the main database and the edited branch. The merge is performed if it does not create a conflict. A second branch is created and edited by a second user. When the second user indicates to merge the second branch back into the main database, differences between the two branches are determined, relative to the main database. If merging the second branch back into the main database on top of the first branch does not create a conflict, a three-way merge is performed of the first branch, the second branch, and the version of the main database from which the first and second branches were generated.

Provided are methods and computer program products for monitoring the performance of network applications executing within operating-system-level virtualization containers. Methods may include enumerating operating-system-level virtualization containers on a networked device; creating a named pipe accessible by at least one application running in each operating-system-level virtualization container; retrieving, via the named pipe, performance data gathered by the at least one application, including an identification of each operating-system-level virtualization container; generating metrics based on the retrieved performance data; and generating an event incorporating the metrics, including operating-system-level virtualization container identifiers.

Provided are methods and computer program products for monitoring and reporting network application performance in a networked device. Methods may include collecting performance data corresponding to at least one application running on the networked device in substantially real time using at least one kernel space driver interface; generating multiple kernel level metrics and multiple user level metrics based on the collected performance data; aggregating the kernel level metrics and the user level metrics that were generated during a predefined time interval; and generating, responsive to aggregating the kernel level metrics and the user level metrics, an event incorporating the aggregated metrics.

Provided are methods and computer program products monitoring the contents of network traffic in a network device. Methods may include collecting, using a kernel space driver interface, network traffic data sent by and/or received at the network device, parsing the collected network traffic data to extract transaction data corresponding to at least one logical transaction defined by a network protocol and storing an indicator of a quantity of the collected network traffic data that was parsed, and generating an event incorporating the extracted transaction data.

Provided are methods and computer program products for aggregating and reporting network application performance metrics by process pool. Methods may include mapping ones of a plurality of processes into one of at least one process pool; and aggregating, for each of the process pools, performance metrics generated for each of the plurality of processes mapped into that process pool.
