此处详细介绍了连接限制,并发限制和命名约束: http://docs.aws.amazon.com/redshift/latest/mgmt/amazon-redshift-limits.html

目前每个群集最多有500个连接和50个并发。

每张桌子可以有一个DISTKEY,详情请点击此处: http://docs.aws.amazon.com/redshift/latest/dg/c_choosing_dist_sort.html

交错排序键限制为八列: http://docs.aws.amazon.com/redshift/latest/dg/t_Sorting_data.html

字符数据类型的最大长度: http://docs.aws.amazon.com/redshift/latest/dg/c_Supported_data_types.html

群集大小由群集中节点的数量和类型决定。在存储方面,当前最大可能是128 x ds2.8xlarge节点,最大存储容量为2 PB: http://docs.aws.amazon.com/redshift/latest/mgmt/working-with-clusters.html
