PARTITION BY { RANGE | LIST | HASH } ( { column_name | ( expression ) } [ opclass ] [, ...] )可选的PARTITION BY子句指定了对表进行分区的策略。 这样创建的表称为分区表。 带括号的列或表达式的列表构成表的分区键。 使用范围或哈希分区时,分区键可以包含多个列或表达式(最多 32 个,但在构...
Write a Python program to create a new list taking specific elements from a tuple and convert a string value to an integer.Sample Solution: Python Code :# Create a list of tuples named 'student_data' containing student information student_data = [('Alberto Franco','15/05/2002','35kg')...
特别需要注意,该参数会影响数据页面存放的单个元组的最大大小,具体换算方法为MAX_TUPLE_SIZE = BLCKSZ - INIT_TD * TD_SIZE,例如用户将INIT_TD数量从4修改为8,单个元组最大大小会减小4 * INIT_TD大小。 取值范围:2~128,默认值为4。 segment 预留参数,暂不支持。 parallel_workers 表示创建索引时起的bg...
