Return sends a specified value back to its caller whereas Yield can produce a sequence of values. We should use yield when we want to iterate over a sequence, but don't want to store the entire sequence in memory. import sys # for example when reading a large file, we only care about...
set odps.function.timeout=xxx; 调整UDF运行超时时长。默认值为1800s。可根据实际情况酌情调大。取值范围为1s~3600s。 set odps.sql.executionengine.batch.rowcount=xxx; 调整MaxCompute一次处理的数据行数。默认值为1024行。可根据实际情况酌情调小。 网络问题 问题现象:调用MaxCompute UDF访问外网时,代码运行会报...
