如何在cqlsh中将大量csv数据导入到cassandra中？

Question

尝试在cassandra中导入批量数据，但无法使用copy命令插入。大约有100000个文件。

尝试

copy dc FROM '/home/hukke/1.csv'  WITH MAXBATCHSIZE=10000;

copy dc FROM '/home/hukke/1.csv'  WITH HEADER=true;

但无法插入它们，这些错误不断弹出。

尝试了多次，并找到了许多用例后，发现这是可行的

COPY dc5 (table columns names ) FROM '/home/hukke/122.csv' WITH HEADER = true AND DELIMITER = ',';
