Abstract
A method and system for live migration of an index in a document store are provided. The method includes creating a new index based on a change request, wherein the change request designates at least one change relative to a current index, wherein the new index includes all mappings and settings of the current index together with the at least one requested change, wherein the new index and the current index are properties of the document store; initiating a reindexing process of the new index by copying documents from the current index to the new index, wherein the current index remains active during the reindexing of the new index; and upon successful completion of the reindexing process, deleting the current index and directing all write and read requests to the new index.
