I am trying to do some disk capacity planning. I have been referring the datastax docs[1] and this older blog post[2]. I have a column family with the following,
row key - 4 bytes column name - 8 bytes column value - 8 bytes max number of non-deleted columns per row - 20160 Is there an effective way to calculate the sizes (or at least a decent approximation) of the bloom filters and partition indexes on disk?
