 **Issue 1**  : ERROR: db_redis [redis_table.c:685]: db_redis_parse_schema(): Failed to open schema directory '/usr/share/kamailio/db_redis/kamailio'
 **Solution** : Redis has differnt schemas for diff module. We have to create a schema defination for each . For exmaple for usrloc module, create file location in sceham_path , and add comma-separated list of column definitions in the format
 <column-name>/<type>[,<column-name>/<type> ...]
