Hi all,
I have a difficulty to represent an example of the calculation of the following formula. Based on throughput requirements one can pick a rough number of partitions. 1. Lets call the throughput from producer to a single partition is P 2. Throughput from a single partition to a consumer is C 3. Target throughput is T 4. Required partitions = Max (T/P, T/C) In the part Choosing topic/partition of this link: https://community.hortonworks.com/articles/80813/kafka-best-practices-1.html Could someone explain to me the calculation ? By showing me step by step the calculation, plz ? I do not remember how the formula applies visually ... Maths, are so far :-) Example T = 20MB/S P = 5MB/S and C = 3MB/S ==> Max(20/5, 20/3) = ??? ==> 20/5 because is the maximum of both ? consequently I need 4 partitions for my topic ? But it does not also depend of the number of producers & consumers ? Thank all. Best regards, Adrien
