The BlockManager in Spark is a key-value distributed storage system tailored for Spark. It runs as a local cache on all nodes, including drivers and executors, providing consistent get and set interfaces for data blocks stored in memory, disk, or off-heap. The BlockManagerMaster manages all BlockManagers in the cluster, coordinating data block replication and migration.

The instantiation of BlockManager occurs concurrently with the creation of SparkEnv, which is the environment setup for a Spark application.
