A leader host obtains individual distributions of data sets ingested by individual hosts of a fleet of hosts over a domain. The leader host compiles the individual distributions over the domain to generate a compiled distribution. The leader host then partitions the domain based at least in part on the generated compiled distribution. These partitions of the partitioned domain are distributed to individual hosts of the fleet of hosts, which causes the individual hosts to process a portion of the distributed date set according to their respective partitions.

Horizontal scaling of time series data

A system for collecting and disseminating log information may comprise a log agent and a log service. A log agent may transmit a log stream to a log service using non-overlapping adjacent subsets of log entries. Each subset may be associated with a unique and monotonically increasing sequence number, which is not incremented until the subset is received and processed by a log service.

Log information transmission integrity

A technology is provided for enabling a partitioned search to be performed on log events from multiple log streams that are stored by multiple hosts. A search query may be submitted to identify the log streams whose log events are to be searched and to indicate a time interval in which log events are to have occurred as indicated by the log events' time stamps. The multiple hosts may search stored log events in parallel and return a set of log-event search results satisfying the search query. A pagination token can be included with the set of log event search results. The pagination token may be used to resume the search if the multiple hosts were not able to completely finish searching the stored log events before the set of log-event search results had to be returned to prevent a timeout of a search client.

Partitioned search of log events

A log data service in a virtual environment that allows customers of a compute service provider to access system, application and custom log files associated with virtual machine instances that are executing. In some embodiments, log data can be received that includes events or messages from virtual machines in a multi-tenant environment. The log data can be transformed into metric data, which can be used by the customer to generate statistics, view graphs, and generally monitor the customer's virtual machine instances. The log data can also be stored as a service so that the customer has a central repository for which to access the log data.
