At its core, the performance of the NodeJS package manager (npm, pnpm, yarn) come down to the performance difference in extracting a TAR to disk on Windows vs. Because our storage layer (s3) is decoupled from our processing layer, we are able to scale our compute environment very elastically. The biggest difference is that the Scheduler:mesos allows the framework to determine whether the resource provided by Mesos is appropriate for the job, thereby accepting or rejecting the resource. HDFS is the Hadoop Distributed File System, which runs on inexpensive commodity hardware. . 2,619 ViewsThe differences tend to be fairly technical, so for most normal use cases, using npm is probably fine and means one less thing to install.
