Abstract: A system for providing low-latency compute capacity is provided. The system may be configured to route incoming code execution requests based on user indications to use specific containers running on a plurality of virtual machine instances. The system may be configured to process a code execution request, identify, based on the user indication that a specific container previously used to handle a request of similar type is to be used for handling the code execution request, and cause the code execution request to be handled using the specific container.

Abstract: Systems and methods are described for generating and executing metaevents within an on-demand code execution environment. The code execution environment can include virtual machine instances that are pre-initialized to enable low latency execution of arbitrary user-defined code. Code execution can typically occur in response to a defined event trigger, such as a call to an application programming interface (API) from an external source. Code execution may also occur in response to metadata regarding the operation of the code execution environment. A user may specify criteria for “metaevents” based on the metadata, and also specify code to be executed in response to satisfaction of the criteria. When the code execution environment determines that the user's criteria is satisfied, a metaevent may be generated that causes execution of the set of code. This execution may, in turn, generate metadata that triggers one or more metaevents.

Abstract: A service manages a plurality of virtual machine instances for low latency execution of user codes. The service can provide the capability to execute user code in response to events triggered on various event sources and initiate execution of other control functions to improve the code execution environment in response to detecting errors or unexpected execution results. The service may maintain or communicate with a separate storage area for storing code execution requests that were not successfully processed by the service. Requests stored in such a storage area may subsequently be re-processed by the service.

Abstract: This disclosure relates to a geographically distributed, multi-master system for storing data records, and associated methods and computer-readable media for replicating data records across geographically distributed data stores of the system in a manner that achieves consistency between data stored in geographically distributed regions as well as deterministic data replication.

Abstract: A system for monitoring incoming code execution requests and scheduling the corresponding code executions is provided. The system may be configured to maintain a plurality of virtual machine instances. The system may be further configured to determine whether at least some of the incoming code execution requests exhibit periodicity, and cause a reduced amount of idle compute capacity to be maintained on the virtual compute system. The system may be further configured to cause additional compute capacity to be added shortly before code execution requests are expected to be received.

Abstract: Compiler functionality is componentized to enable use across different contexts. Conventionally tightly coupled functionality is decoupled and an interface afforded to facilitate interaction with compiler components/subcomponents in various scenarios. In one instance, compiler components can be employed across compile time and runtime. Compile time functionality can be employed at runtime and runtime functionality utilized at compile time thereby blurring the line between time dimensions.

Abstract: A batch compiler is employed to enable compilation of code provided at runtime. A managed application receives code during execution and invokes the compiler to transform the code to enable it to execute within the context of the receiving application. Among other things, employment of a batch compiler preserves investments made to such compilers while also opening up new scenarios in application scripting and/or hosting that are otherwise unavailable.
