无法使用cassandra计数器列与cassandra gem [英] Unable to use cassandra counter column with cassandra gem

问题描述

我使用cqlsh通过以下命令创建了一个列系列：

I have created a column family by following command using cqlsh:

create table mystats (key PRIMARY KEY, count counter);

现在从cqlsh我可以增加计数器列，但是当我试图这样做从cassandra gem，as adviced at：
有没有任何Ruby客户端Cassandra与计数器和超列？

Now from the cqlsh I am able to increase the counter column but when I attempt to do this from cassandra gem, as adviced at: Are there any Ruby clients for Cassandra with counters and supercolumn?

所以当我使用：

@stats.add(:mystats, 'randomkey', 1, 'count')

我得到一个错误：

Cassandra :: AccessError在/ client无效列族mystats

Cassandra::AccessError at /client Invalid column family "mystats"

当我进一步查看它时，我发现错误是从gem中提出的：
在文件中： https://github.com/twitter/cassandra/blob/master/lib/cassandra/ columns.rb

When I further looked into it, I found that the error is raised from the gem: in file: https://github.com/twitter/cassandra/blob/master/lib/cassandra/columns.rb

def column_family_property(column_family, key)
      cfdef = schema.cf_defs.find {|cfdef| cfdef.name == column_family }
      unless cfdef
        raise AccessError, "Invalid column family \"#{column_family}\""
      end
      cfdef.send(key)
    end

任何人都可以指出我在这里可能犯的错误。 p>

Can anyone please point out what I might be doing wrong here..

推荐答案

该客户端尚未更新以支持CQL3。我不知道有CQL3的Ruby客户端，所以你最好的选择是创建一个Thrift兼容表（TLDR add WITH COMPACT STORAGE 到你的表定义） 。

That client has not yet been updated to support CQL3. I'm not aware of a CQL3-aware Ruby client, so your best bet is probably to create a Thrift-compatible table (TLDR add WITH COMPACT STORAGE to your table definition).
