MongoDB scales horizontally using sharding. As a consequence, an idealized distributed MongoDB deployment requires at least three separate servers, even in the case of just one primary and one secondary.

It has a single responsibility, which is to resolve the election of the new primary. If the replicated MongoDB deployment only has a single secondary member, a separate daemon called an arbiter must be added to the set. Secondaries can optionally serve read operations, but that data is only eventually consistent by default. When a primary replica fails, the replica set automatically conducts an election process to determine which secondary should become the primary.

Secondary replicas maintain a copy of the data of the primary using built-in replication. All writes and reads are done on the primary replica by default. Each replica-set member may act in the role of primary or secondary replica at any time. A replica set consists of two or more copies of the data. MongoDB provides high availability with replica sets. Queries can also be configured to return a random sample of results of a given size.įields in a MongoDB document can be indexed with primary and secondary indices or index. Queries can return specific fields of documents and also include user-defined JavaScript functions. MongoDB supports field, range query, and regular-expression searches.
