      > MongoDB does lock a document that is being modified by a transaction. However, other sessions that attempt to modify that document do not block. Rather, their transaction is aborted, and they are required to retry the transaction. This is potentially wasteful since other operations in the transaction will need to be re-executed, and also results in requests being serviced in a non-deterministic order. <\/p><\/div>\n<\/p><\/div>\n<\/li>\n
