I didn¹t read your question properly. Collections are limited to 64K items, not 64K bytes per item.

I have a column daycount list<BigInt>. The column is storing a count. Every few secs a new count is appended. The total count for the day is the sum of all items in the list. My application logs indicate I wrote about 110000 items to the column for a particular row. Assume row key is day_timestamp. But when I do a read on the column I get back a list with only 43000 items. Checked with both java driver and CQL. There are no errors or exceptions anywhere. There is this statement in the WIKI "Collection values may not be larger than 64K". I assume this refers to 1 item in a collection. Has anyone else seen an issue like this ? regards MJ -- http://khangaonkar.blogspot.com/
