    Abstract: Methods, systems, and computer-readable media for distributed transactions across multiple consensus groups are disclosed. A distributed transaction system comprises a proposer and a plurality of consensus groups, including a first consensus group comprising a first plurality of members and a second consensus group comprising a second plurality of members. The proposer proposes a transaction to at least a portion of the first consensus group and at least a portion of the second consensus group. A majority of the members in the first consensus group agree to perform the transaction, where the transaction is selected from a plurality of proposed transactions involving the first consensus group. A majority of the members in the second consensus group also agree to perform the transaction. The members of the first and second consensus groups perform the transaction to update a plurality of stored replicas.

    Abstract: Systems and methods are provided for efficiently configuring an execution environment for an on-demand code execution system to handle a single request (or session) for a single user. Once the session or request is complete, the execution environment is reset, such as by having the hardware processor state, memory, and storage reset. In particular, prior to the execution of code, state of the execution environment of the host computing device is retrieved, such as hardware processor(s), memory, and/or storage state. Moreover, during execution of the code instructions, intermediate state can be gathered. Following the execution of the code, the execution environment is reset based on the saved state related to the hardware processor(s), memory, and/or storage. A subsequent code execution securely occurs in the execution environment and the execution environment is reset again, and so forth.

    Abstract: Data replication groups may be used to store data in a distributed computing environment. The data replication groups may include a set of nodes executing a consensus protocol to maintain data durably. During the execution of the set of nodes various nodes may become stale or otherwise obtain a state that is inconsistent with at least one other node of the data replication group. A catch up algorithm may be employed in which a set of teachers is initialized, the various node which may be stale may select a teacher from the set of teachers and perform learning operations. This process may be repeated until the state of the various nodes is current with at least one other node of the data replication group.

    Abstract: Customers of shared resources in a multi-tenant environment can modify operational parameters of electronic resources. A customer can be provisioned a data volume of a specified size, storage type (e.g., hard disk drive or solid state device), committed rate of input/output operations per second, and/or geographical location, for example. The customer can subsequently modify any such operational parameters by submitting an appropriate request, or the operational parameters can be adjusted automatically based on any of a number of criteria. Data volumes for the customer can be migrated, split, or combined in order to provide the shared resources in accordance with the modified operational parameters.

    Abstract translation: 在多租户环境中共享资源的客户可以修改电子资源的运行参数。 例如，客户可以设置指定大小的数据量，存储类型（例如，硬盘驱动器或固态设备），每秒输入/输出操作的承诺速率和/或地理位置。 客户可随后通过提交适当的请求修改任何此类操作参数，或者可以根据多个标准中的任何一个自动调整操作参数。 可以迁移，拆分或组合客户的数据卷，以便根据修改的操作参数提供共享资源。
