収集データが 64K を超える場合の代替手段はありますか。
カサンドラのドキュメントによると
Observe the following limitations of collections:
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.
