 Description   

secondaryThrottle has been changed to allow finer-grained control of write concerns for chunk migrations. Note the difference in specification between the balancer config document and the commands.

Most useful information at https://jira.mongodb.org/browse/SERVER-14041?focusedCommentId=660934&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-660934

Needs to be changed at (at least) the following locations:

http://docs.mongodb.org/manual/tutorial/configure-sharded-cluster-balancer/#sharded-cluster-config-secondary-throttle

http://docs.mongodb.org/manual/core/sharding-chunk-migration/

http://docs.mongodb.org/manual/reference/command/moveChunk/

Hi samk,

When debugging SERVER-16842, we found that the default _secondaryThrottle was false in 2.6 and changed to true in 2.8, according to SERVER-14041, while the documentation of 2.6 says the opposite. According to renctan, we don't have plan to change this for 2.6.

Thanks,
Siyuan
