Does anyone know the history of why some of the columns in the nova tables are defined as Text (sql TEXT or CLOB) instead of String (sql VARCHAR) when the lengths of their values are normally small? For mysql and other databases, the performance of accessing VARCHAR is much faster than TEXT or CLOB because VARCHAR data is stored inline with the table. If these TEXT columns are fetched frequently and their lengths are small, can they be defined as VARCHAR?? Any thoughts/suggestions?
For example (table.column): instances.launched_on compute_nodes.hypervisor_type compute_nodes.cpu_info Thanks..
