MULTI-SITE CLUSTERING

摘要

According to various embodiments, techniques are described for managing data within a multi-site clustered data intake and query system. A data intake and query system as described herein generally refers to a system for collecting, retrieving, and analyzing data. In this context, a clustered data intake and query system generally refers to a system environment that is configured to provide data redundancy and other features that improve the availability of data stored by the system. For example, a clustered data intake and query system may be configured to store multiple copies of data stored by the system across multiple components such that recovery from a failure of one or more of the components is possible by using copies of the data stored elsewhere in the cluster.

1. A method comprising:
receiving data at an indexer associated with a first site; storing, by the indexer, at least one grouped subset of the data in a data store accessible by the indexer; receiving data replication instructions including a list of one or more peer indexers, the one or more peer indexers including at least one peer indexer associated with a second site; and sending the at least one grouped subset of the data to the one or more peer indexers; receiving instructions indicating whether the indexer has primary responsibility for searching in the data store to which the indexer has access the at least one grouped subset of the data.
