借助索引,GetPartitions 查询将尝试获取分区的子集,而不是加载表中的所有分区。 我们可以使用 Glue 爬网程序产生出table_with_index表单与分区资料,并储存于 Glue Data Catalog 中,然后在Tables 点选产生出来的表单,点选右上角的 Partitions and indices,然后点选 Add new index 创建分区索引。命名...

However, the partition function of the index and the base table must be essentially the same, in that 1) the arguments of the partition functions have the same data type, 2) they define the same number of partitions, and 3) they define the same boundary values for partitions. The Tuning...
