我正在创建以下架构:
CREATE TABLE stats_by_site_tracking_hourly (
d_tally text, -- 2016-02
d_date timestamp, -- 2016-02-01 13
site_id int,
is_new_member int, -- 1/0
device text, -- desktop/tablet/mobile/unknown
tracking_medium text,
tracking_source text,
tracking_campaign text,
tracking_term text,
accepted counter,
adjusted_accepted counter,
rejected counter,
adjusted_rejected counter,
error counter,
impressions_positive counter,
adjusted_impressions_positive counter,
impressions_negative counter,
adjusted_impressions_negative counter,
revenue counter,
adjusted_revenue counter,
reversals_rejected counter,
reversals_revenue counter,
PRIMARY KEY ((d_tally), site_id, d_date, is_new_member, device, tracking_medium, tracking_source, tracking_campaign, tracking_term)
);
当我运行该语句时,似乎快速处理前几列,但是当它移动到计数器列时,它会逐渐减慢每列的速度。
我已将此声明保持运行5分钟,但仍未完成。
有人能对这种行为有所了解吗?
This是CQLSH在创建表时的样子,截图时它没有进展20分钟左右。
我只是将create table命令放到一行中,它立即起作用。
CREATE TABLE stats_by_site_tracking_hourly ( d_tally text, d_date timestamp, site_id int, is_new_member int, device text, tracking_medium text, tracking_source text, tracking_campaign text, tracking_term text, accepted counter, adjusted_accepted counter, rejected counter, adjusted_rejected counter, error counter, impressions_positive counter, adjusted_impressions_positive counter, impressions_negative counter, adjusted_impressions_negative counter, revenue counter, adjusted_revenue counter, reversals_rejected counter, reversals_revenue counter, PRIMARY KEY ((d_tally), site_id, d_date, is_new_member, device, tracking_medium, tracking_source, tracking_campaign, tracking_term) );

我在这里提出了这个错误:here
原来这是由于架构中的选项卡。 CQLSH每次进入选项卡时都试图自动完成。

我在几台计算机上遇到过同样的问题,看来它是cqlsh>中的一个错误。互动壳。如果从终端执行脚本,它将立即执行:
> cqlsh -f your_cql_script.cql <hostname>
无论大小表如何,都会立即运行,并且可以为您节省大量时间。
