Is there any governor limit on the number of records in a particular object in Salesforce ?

Hi Nikita,

As far as I’m aware the only limit is your data storage, you can see what you’ve used by going to Setup -> Administration Setup -> Data Management -> Storage Usage.

In one of the Orgs I work with I can see one object has almost 2GB of data for just under a million records, and this accounts for a little over a third of the storage available. Your storage space depends on your Salesforce Edition and number of users.  See here for details.
