Abstract: Techniques are provided for scheduling data operations for a given query based upon a query-cost model that analyzes the cost of scheduling data operations based upon their operation cost and the type of resources needed for the operation. In an embodiment, a database server receives a set of operations for a query. The database server determines a set of leaf operation nodes from the set of data operations, where the set of leaf operation nodes includes operation nodes that do not depend on the execution of other nodes within the set of data operations. The database server compares operation costs between the leaf operation nodes to determine which leaf operation node to insert into a scheduled order set. The database server inserts the leaf operation node into the scheduled order set. Then the database server iteratively determines new leaf operation nodes and performs cost analysis on remaining leaf operation nodes to generate a set of scheduled data operations.

The CFI method includes intercepting a system call originating from execution of the protected process executing in the runtime environment.

The fast path attempts to establish a match between the processor trace packet and a program control flow (edge) entry within a credit-labeled control flow graph (CFG) definition having an associated credit value. The credit value represents a degree to which the program control flow is credible.

The program code has an associated event loop handling asynchronous event calls and callbacks within the program code. Handlers of the event loop associated with the asynchronous event calls and the callbacks within the program code, except a handler of the event loop associated with the synchronous operation method, are temporarily disabled. The synchronous operation method performs an operation specified within the call request, while the event loop is running with the handlers in question temporarily disabled. The synchronous operation method, upon completion, calls back its handler with results of performance of the operation, and the disabled handlers are reenabled.

Abstract: A tracing controller may utilize a binary execution trace mechanism to trace execution of compiled application machine code. The tracing controller may initiate hardware tracing to gather control-flow hardware traces of a method executing on a processor configured to generate hardware tracing information. The controller may generate a profile based on the hardware tracing information and initiate re-compiling or re-optimizing of the method in response to determining that the new profile differs from the previous profile. The controller may repeatedly profile and re-optimize a method until profiles for the method stabilize. Profiling and hardware tracing of an application may be selectively enabled or disabled allowing the controller to respond to later phase changes in application execution by re-optimizing, thereby potentially improving overall application performance.

For example, the technique can use the extracted data to provide search results in response to a user query entered into a search engine. Alternately, the extracted static and/or dynamic data can be used by an advertisement engine to select application-specific advertisements. Or the data can be used by a recommendation engine to make recommendations for goods/services.
