Yes, I¹ve experienced this as well. It looks like you¹re getting the number
of items inserted mod 64K.

Subject:  Any Limits on number of items in a collection column type


On C* 2.0.0. 3 Node cluster.

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 ?
