I am planning to store the records in a particular object in an HBase table. I want to know if a new record Id is created lexicographically.
the salesforce ids are not generated sequentially. But there is prefix format used for generating an id.
the first 3 digits - unique for object example : for accounts, all record ids start with 001 for cases, all record ids start with 005 the next 2 digits - obtained from the Server id (for na1 - D0)
if you are looking at 15 digit ids, then there can be 2 records which have same character sequence but differ only in the case.
