Subject Re: Cassandra: maximum size of collection list type
Date Thu, 01 Dec 2016 18:38:08 GMT
A 64k element list will not be performant. Even 10% of that will be painful for many users.

Subject: Re: Cassandra: maximum size of collection list type


As doc says:

 The maximum size of an item in a collection is 64K.
Keep collections small to prevent delays during querying because Cassandra reads a collection
in its entirety. The collection is not paged internally.
As discussed earlier, collections are designed to store only a small amount of data.
Never insert more than 64K items in a collection. 
If you insert more than 64K items into a collection, only 64K of them will be queryable, resulting
in data loss.

You can read it in the docs but i think it was 2^16 aka 64k
