TableStats getTableStats(String vdbName, int vdbVersion, Table table);
void setTableStats(String vdbName, int vdbVersion, Table table, TableStats tableStats);
ColumnStats getColumnStats(String vdbName, int vdbVersion, Column column);
void setColumnStats(String vdbName, int vdbVersion, Column column, ColumnStats columnStats);
