Linux 压缩sas数据集时会增加其大小？
我编写了一段代码，用compress=yes选项创建SAS数据集。也就是说，生成的数据集正在以更大的大小进行压缩，如日志中所示Linux 压缩sas数据集时会增加其大小？,linux,sas,Linux,Sas,我编写了一段代码，用compress=yes选项创建SAS数据集。也就是说，生成的数据集正在以更大的大小进行压缩，如日志中所示 1374 +proc sql; 1375 + create table seg.KRG_EO_PVS_CUST_PROD_&op_cyc. 1376 + ( 1377 + COMPRESS = YES 1378 + ) as 1379 + select ^L32

NOTE: Compressing data set SEG.KRG_EO_PVS_CUST_PROD_20150701 increased size by 43.27 percent.
Compressed is 1961732 pages; un-compressed would require 1369265 pages.
NOTE: Table SEG.KRG_EO_PVS_CUST_PROD_20150701 created, with 346423801 rows and 4 columns.
我只想知道发生这种情况的可能原因是什么SAS压缩非常简单，
compress=yes
