有Cassandra的任何Ruby客户端与计数器和超列？ [英] Are there any Ruby clients for Cassandra with counters and supercolumn?

问题描述

有支持计数器和超列的Cassandra有任何Ruby客户端吗？

Are there any Ruby clients for Cassandra with support of counters and supercolumns?

1）gem cassandra不支持计数器

1) gem cassandra doesn't support counters

2）gem cassandra-cql不支持超列（cql不支持它们）

2) gem cassandra-cql doesn't support supercolumns (cql doesn't support them)

推荐答案

'cassandra' gem支持计数器，它没有很好的文档。支持已于2011年5月添加（ a1a085469 ）。要增加计数器：

The 'cassandra' gem does support counters, its just not well documented. Support was added in May 2011 (a1a085469). To increment a counter:

@twitter.add(:UserCounters, 'bob', 5, 'tweet_count')

其中

• code>：UserCounters 是列族


• / li>

• 5 是通过
增加计数器的金额

• tweet_count'是column_name

• :UserCounters is the column family
• 'bob' is the row key
• 5 is the amount to increment the counter by
• 'tweet_count' is the column_name
