> AUTHZ_PATH does not have index on the foreign key AUTHZ_OBJ_ID. When the
> number of entries become really large, a command like "select * from
> AUTHZ_PATH where AUTHZ_OBJ_ID = 8311512" becomes very slow because it results
> in table scan.
> To improve performance, we should add index for its foreign key in table
> AUTHZ_PATH.
> The sql script to do this in Oracle is "CREATE INDEX AUTHZ_PATH_FK_IDX on
> AUTHZ_PATH(AUTHZ_OBJ_ID);"
