方法详细资料

getName

public String getName()

public void alterDomain(BSONObject options)
                 throws BaseException

参数:

options - the options user wants to alter:

• Groups: The list of replica groups' names which the domain is going to contain. eg: { "Groups": [ "group1", "group2", "group3" ] }, it means that domain changes to contain "group1", "group2" and "group3". We can add or remove groups in current domain. However, if a group has data in it, remove it out of domain will be failing.
• AutoSplit: Alter current domain to have the ability of automatically split or not. If this option is set to be true, while creating collection(ShardingType is "hash") in this domain, the data of this collection will be split(hash split) into all the groups in this domain automatically. However, it won't automatically split data into those groups which were add into this domain later. eg: { "Groups": [ "group1", "group2", "group3" ], "AutoSplit: true" }
