CORE-1218 A bug in HarperDB 2.3.0 was identified related to manually calling the create_attribute operation. This bug caused secondary indexes to be overwritten by the most recently inserted or updated value for the index, thereby causing a search operation filtered with that index to only return the most recently inserted/updated row. Note, this issue does not affect attributes that are reflexively/automatically created. It only affects attributes created using create_attribute. To resolve this issue in 2.3.0 or earlier, drop and recreate your table using reflexive attribute creation. In 2.3.1, drop and recreate your table and use either reflexive attribute creation or create_attribute.
CORE-1219 Increased maximum table attributes from 1000 to 10000
