hi,
I created table in google Big table datastore ,In that the i set primary key using
@annotations as follows
@Id
@Column(name = "groupname")
private String groupname;
@Basic
private String groupdesc;
I worked corretly,but it override the previous record,how to solve this
for eg
if i entered
groupname=group1
groupdesc=groupdesc
than it accept after that i enter same groupname it override previous record for eg groupname=group1 groupdesc=groups
this record override previous one.
