All the dynamic properties can be replaced lazily when they are read. > We can go one step ahead in this case. Th IndexSchema object is immutable . So if there are no core properties then the same IndexSchema object can be used across all the cores -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
