Elastic Search Notes

“The act of storing data in Elasticsearch is called indexing, but before we can index a document, we need to decide where to store it” “Relational DB ⇒ Databases ⇒ Tables ⇒ Rows ⇒ Columns Elasticsearch ⇒ Indices ⇒ Types ⇒ Documents ⇒ Fields” “_index Where the document lives _type The class of object that the document represents _id The unique identifier for the document” Actually, in Elasticsearch, our data is stored and indexed in shards, while an index is just a logical namespace that groups together one or more shards.
