🚨ATENCIÓN: Juan Daniel Oviedo acaba de decir que no se unirá a una campaña sucia, machista y homofóbica como la de Abelardo de la Espriella.
Por fin algo coherente de este señor después de la pisoteada que le metieron en la campaña de Paloma Valencia.
si Mattelsa se cae, yo la empujé
si Mattelsa opina, no estoy de acuerdo
si Mattelsa falla, crítico
si Mattelsa tiene 100 haters, yo soy uno de ellos
si Mattelsa tiene 1 hater, ese soy yo
si Mattelsa no tiene haters, es porque yo habré muerto.
Los EEUU no pueden tratar como delincuentes a los migrantes Colombianos.
Desautorizo la entrada de aviones norteamericanos con migrantes colombianos a nuestro territorio.
EEUU debe establecer un protocolo de tratamiento digno a los migrantes antes que los recibamos nosotros.
Why is Kafka fast?
There are many design decisions that contributed to Kafka’s performance. In this post, we’ll focus on two. We think these two carried the most weight.
1️. The first one is Kafka’s reliance on Sequential I/O.
2️. The second design choice that gives Kafka its performance advantage is its focus on efficiency: zero copy principle.
The diagram below illustrates how the data is transmitted between producer and consumer, and what zero-copy means.
🔹Step 1.1 - 1.3: Producer writes data to the disk
🔹Step 2: Consumer reads data without zero-copy
2.1: The data is loaded from disk to OS cache
2.2 The data is copied from OS cache to Kafka application
2.3 Kafka application copies the data into the socket buffer
2.4 The data is copied from socket buffer to network card
2.5 The network card sends data out to the consumer
🔹Step 3: Consumer reads data with zero-copy
3.1: The data is loaded from disk to OS cache
3.2 OS cache directly copies the data to the network card via sendfile() command
3.3 The network card sends data out to the consumer
Zero copy is a shortcut to save multiple data copies between the application context and kernel context.
