Description

I have the following in trunk:

RowKey: b
=> (column=a, value=38383838383838383838, timestamp=1317421952793000)
=> (column=d, value=617364646661736466, timestamp=1317420968944000)
=> (column=e, value=38383838383838383838, timestamp=1317421096152000)
=> (column=f, value=33343334333433343334, timestamp=1317422838818000)
=> (column=g, value=33343334333433343334, timestamp=1317422565130000)
=> (column=i, value=33343334333433343334, timestamp=1317422879258000)
=> (column=j, value=33343334333433343334, timestamp=1317422814873000)

every thing is flushed to the sstables, but not in the same sstables, and the columns are in some what 'random' form:

/var/lib/cassandra/data/testks/testcf-h-10-Data.db
{
"61": [["0c","76",1317405903119000], ["0d","76",1317405977002000], ["7a","38383838383838383838",1317422276322000]],
"62": [["61","38383838383838383838",1317421952793000], ["63","4e864303",1317421827329000,"d"], ["64","617364646661736466",1317420968944000], ["65","38383838383838383838",1317421096152000], ["67","33343334333433343334",1317422565130000], ["78","33343334333433343334",1317422394097000], ["7a","38383838383838383838",1317421982057000]]
}
/var/lib/cassandra/data/testks/testcf-h-12-Data.db
{
"62": [["6a","33343334333433343334",1317422814873000]]
}
/var/lib/cassandra/data/testks/testcf-h-13-Data.db
{
"62": [["66","33343334333433343334",1317422838818000]]
}
/var/lib/cassandra/data/testks/testcf-h-14-Data.db
{
"62": [["6f","33343334333433343334",1317422867106000]]
}
/var/lib/cassandra/data/testks/testcf-h-15-Data.db
{
"62": [["69","33343334333433343334",1317422879258000]]
}

then i basically make a call to get key=b with all the column names (yes included column names that didn't exist to save time):

ColumnFamilyResult<String, String> queryColumns = template.queryColumns("b", Arrays.asList("a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z"));

(let me know if it would be easier to just upload the sstables to the ticket)
