Any Limits On Number Of Items In A Collection Column Type

Hi,
I have a column  daycount list. 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

Yes, I�ve experienced this as well. It looks like you�re getting the number
of items inserted mod 64K.

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

Thanks. I guess I can work around by maintaining hour_counts (which will
have fewer items) and adding the hour counts to
get day counts.

Alternatively you can use clustering columns to store very big collections.
Beware of not making a row too wide though (use bucketing)

How does "collection items terminated by" work on a nested structure? Say the table is created with the DDL: CREATE TABLE table_1(f1 int, f2 string, f3 array ) ROW FORMAT DELIMITED FIELDS TERMINATED BY '|' COLLECTION ITEMS TERMINATED BY ',' MAP KEYS TERMINATED BY '=' LINES TERMINATED BY '\'n' STORED AS TEXTFILE; I guess comma seperator wll be used for the items in the outer most structure (i.
Dear All, I am a little bit confused from self type and generics. I have to implement a hiearchy of custom generic collection implementing a filter function, and of course I want that each collection when filtered return a collection of the same type. What is the right way to implement this? Best Regards Edmondo

Hi spark users, Do you know how to access rows of row?

Hi, I understand that collection type column are supported via cql3 only. Can anybody please share how actually such mutations happen? I can see that actual column value is clubbed with column name in form of a ColumnGroupMap(type Collection). But not able to identify how it works internally within Cassandra? Any thoughts? -Vivek
