45. MongoDB does not have support for
traditional locking or complex
transactions with rollback. MongoDB
aims to be lightweight, fast, and
predictable in its performance. This
is similar to the MySQL MyISAM
autocommit model. By keeping
transaction support extremely simple,
MongoDB can provide greater
performance especially for
partitioned or replicated systems
with a number of database server
processes.
56. Side effects may
include...
Problems working on 32-bit, large data
storage problems, write falures, no error
value return, sophicticated schema design,
limited update operation, case sensitive
queries, type sensitive fields, write
locks, replica sets restrictions,
unexpected data loss, sharding size
limitations, no transactions, nausea,
going back to RDBMS
