Index modules are a complex subject; they are defined per index and control every aspect of an index. There are two types of settings for an index Static: Can usually be defined at the creation time or when the index is closed. index can be closed by invoking the _close api. E.g. index.number_of_shards, index.shard.check_on_startup etc. Dynamic: Can be changed on the live index using index settings api. E.g. index.number_of_replicas, index.refresh_interval etc. More details available here.

Pipelines is a smooth way of processing some incoming data. In this blog, I will walk through some of the items I have tried my hands on. Pipeline # A pipeline is a definition of a series of processors that are to be executed in the same order as they are declared.

_reindex # Official documentation here. This API is meant for copying data from one index to another. It is especially useful when you are copying data from one index to another.
