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/kafkabestpractices1.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
