A computer-implemented method comprises receiving, by a processor, search requests to search a database; receiving a reindex request to reindex information in the database based on a new ontology for the database or a new number of shards for a first index server; initiating, by the processor, generation of a second index for the database while a first index managed by the first index server continues to be used live for responding to received search requests; completing the generation of the second index during a certain period when no search request is sent to the first index server; and in response to the completing, using the second index live for responding to received search requests.

Database live reindex

Systems and methods are provided for storing a first data object comprising a first set of immutable components, the first data object being associated with a corresponding second data object stored by a remote replication system. A difference is determined between the first set of immutable components of the first data object and a second set of immutable components of the corresponding second data object. A subset of immutable components is identified from the first set of immutable components based on the difference. The subset of immutable components from the first set of immutable components is provided to the remote replication system over a communication network.

Systems and methods for data replication synchronization

Systems and methods for live reindexing include receiving, at a dispatch server, a request to reindex a database, wherein, at the time the request to reindex is received, the dispatch server is configured to send queries for information in the database to a first index server, the first index server comprising a first index of information in the database. The systems and methods further include, responsive to receiving the request to reindex and while the database is live, generating a second index of the information in the database, storing the second index at a second index server, and configuring the dispatch server to use the second index server as a live index server and to no longer use the first index server as a live index server.
