The JSON you are showing below is an export from cassandra? { "74657374": [["data", "{"foo":"bar"}", 1308209845388000]] } Does this work? { 74657374: [["data", {foo:"bar"}, 1308209845388000]] } -sd On Thu, Jun 16, 2011 at 9:49 AM, Timo Nentwig wrote: > On 6/15/11 17:41, Timo Nentwig wrote: >>

No. Upgraded to 0.8 and monitor the systems more. we schedule a repair every 24hrs via cron and so far no problems.. On Jun 15, 2011 5:44 PM, "AJ" wrote: > Sasha, > > Did you ever nail down the cause of this problem? > > On 5/31/2011 4:01 AM, Sasha Dolgy wrote: >>

Re: count column in Cassandra

probably helpful if you change the subject when posting about a different topic. Is your question about "counters" or the "count" function? Counters are cool. Count allows you to determine how many columns exist in a row. -sd On Mon, Jun 13, 2011 at 5:27 PM, Sijie YANG wrote: > Hi, All > I am
