Abstract: A method for operating an automated storage and retrieval system includes transferring a first item storage container from an aisle to a first region of a first storage location, positioning a second item storage container in the aisle proximate the first item storage container, interlocking the second item storage container to the first item storage container by engaging a releasable coupling structure extending there between, and applying, in a first direction transverse to the aisle, a force to the second item storage container sufficient in magnitude and duration to cause the first item storage container to occupy the second region of the first storage location and the second item storage container to occupy the first region of the first storage location, whereby the first and second item storage containers remain interlocked while in the first storage location.

Abstract: Techniques and mechanisms are disclosed to execute data searches using generation identifiers. In general, a method of executing the searches comprises broadcasting, from a search head, a first query to a plurality of indexers in a cluster, wherein a portion of the first query is directed to a set of data, and wherein the set of data comprises time-stamps within a particular time frame. The method further comprises providing, with the first query, a first generation identifier for the set of data, wherein the first generation identifier identifies a first indexer from the plurality of indexers to serve as a primary indexer for responding to queries that comprise the first generation identifier and that pertain to the set of data, wherein one or more indexers in the cluster other than the first indexer are designated as secondary indexers, wherein the secondary indexers are configured to ignore queries that pertain to the set of data and that comprise the first generation identifier.

Abstract: Techniques and mechanisms are disclosed to increase the availability of summary data within a clustered data intake and query system by replicating the summary data within the cluster. In general, summary data may store “pre-computed” results for one or more search queries and can be used by indexers of a cluster to process subsequent instances of the same search queries. At a high level, replication of summary data within a cluster may include ensuring that each instance of summary data created by an indexer of a cluster is replicated to other indexers within the cluster that store copies of the same grouped subset(s) of data to which the summary data relates. In this manner, if one or more indexers of an indexer cluster fail, other indexers of the cluster can make immediate use of replicated copies of the summary data without re-creating it.

Abstract: Techniques and mechanisms are disclosed to optimize the size of index files to improve use of storage space available to indexers and other components of a data intake and query system. Index files of a data intake and query system may include, among other data, a keyword portion containing mappings between keywords and location references to event data containing the keywords. Optimizing an amount of storage space used by index files may include removing, modifying and/or recreating various components of index files in response to detecting one or more storage conditions related to the event data indexed by the index files. The optimization of index files generally may attempt to manage a tradeoff between an efficiency with which search requests can be processed using the index files and an amount of storage space occupied by the index files.

Abstract: A method and apparatus are provided for storing or retrieving items to/from a plurality of destinations areas. The items are loaded onto one of a plurality of independently controlled delivery vehicles. The delivery vehicles follow a path to/from the destination areas that are positioned along the path. The destination areas are configured such that the destination areas have a depth to accommodate a plurality of containers in a horizontal line one behind another. The containers may be releasable interconnected so that retrieving one of the interconnected containers displaces one or more connected containers.
