Techniques are described for facilitating access of users to tasks that are available to be performed, such as via a task exchange system that serves as an intermediary to facilitate performance by some task performer users of tasks supplied by other task requester users. The techniques may include automatically providing a particular group of task performer users with access to a supply of available tasks that are appropriate for those task performer users, such as based on an aggregate probability or other likelihood measure that the task performer users as a group will collectively accept to perform those tasks in a specified manner. More generally, the affinity and/or appropriateness of a group of users to perform one or more tasks may be based on various information related to the users, including past task performance behavior of those users, and/or qualifications or more general reputational aspects of those users.

Providing access to tasks that are available to be performed

Techniques are described for providing enhanced access to stored data and related functionality, such as data stored by a system across multiple alternative storage partitions. At least some of the stored data may be specific to particular users who interact with the system, such as for users to perform tasks supplied by other users. The enhanced data access techniques may include storing at least a subset of each user's associated data on a single storage partition, and then efficiently identifying the storage partition corresponding to a user so that requests from that user may be handled by a computing node associated with that corresponding storage partition. Furthermore, additional data access enhancement techniques may relate to initially identifying an appropriate storage partition for a user and/or for migrating existing user data to a new partition identified as being appropriate for a user.
