The 'cassandra' gem does support counters, its just not well documented. Support was added in May 2011 (a1a085469). To increment a counter:
'cassandra'宝石确实支持计数器,它只是没有很好的记录。 2011年5月增加了支持(a1a085469)。增加一个计数器:
@twitter.add(:UserCounters, 'bob', 5, 'tweet_count')
Where
-
:UserCountersis the column family -
'bob'is the row key -
5is the amount to increment the counter by -
'tweet_count'is the column_name
:UserCounters是列族
'bob'是行键
5是增加计数器的数量
'tweet_count'是column_name
