  +The new index is automatically configured according to any matching <<glossary-index-template,index templates>>. 
   For example, if you're indexing log data, you might use rollover to create daily or weekly indices.

  +[[glossary-rollup-index]] rollup index ::
  +// tag::rollup-index-def[]
  +A special type of index for storing historical data at reduced granularity. 
  +Documents are summarized and indexed into a rollup index by a <<glossary-rollup-job,rollup job>>.
  +// end::rollup-index-def[]
  +
  +[[glossary-rollup-job]] rollup job ::
  +// tag::rollup-job-def[]
  +A background task that runs continuously to summarize documents in an index and 
  +index the summaries into a separate rollup index. 
  +The job configuration controls what information is rolled up and how often.

  [[glossary-cluster]] cluster ::
  // tag::cluster-def[]
  A cluster consists of one or more <<glossary-node,nodes>> which share the
  same cluster name. Each cluster has a single master node which is
  chosen automatically by the cluster and which can be replaced if the
  current master node fails.
  // end::cluster-def[]
  
  [[glossary-ccr]] {ccr} (CCR)::
  // tag::ccr-def[]
  The {ccr} feature enables you to replicate indices in remote clusters to your
  local cluster. For more information, see 
  {ref}/xpack-ccr.html[{ccr-cap}].  
  // end::ccr-def[]
    
  [[glossary-ccs]] {ccs} (CCS)::
  // tag::ccs-def[]
  The {ccs} feature enables any node to act as a federated client across
  multiple clusters.
  See {ref}/modules-cross-cluster-search.html[Search across clusters].

negative.code: // tag::index-template-def-short[]
  Defines settings and mappings to apply to new indexes that match a simple naming pattern, such as _logs-*_. 
  // end::index-template-def-short[]
  
  An index template can also attach a lifecycle policy to the new index.
  Index templates are used to automatically configure indices created during <<glossary-rollover,rollover>>. 
  // end::index-template-def[]

  [[glossary-leader-index]] leader index ::  
  // tag::leader-index-def[]
  The source index for <<glossary-ccr,{ccr}>>. A leader index exists
  on a remote cluster and is replicated to 
  <<glossary-follower-index,follower indices>>.
  // end::leader-index-def[]
  
  [[glossary-local-cluster]] local cluster ::
  // tag::local-cluster-def[]
  The cluster that pulls data from a <<glossary-remote-cluster,remote cluster>> in {ccs} or {ccr}.
