class FileMetadataMaterializationTracker extends LoggingShims

An instance of this class tracks and controls the materialization usage of a single command query (e.g. Backfill) with respect to the driver limits. Each query must use one instance of the FileMaterializationTracker.

tasks - tasks are the basic unit of computation. For example, in Backfill, each task bins multiple files into batches to be executed.

A task has to be materialized in its entirety, so in the case where we are unable to acquire permits to materialize a task we acquire an over allocation lock that will allow tasks to complete materializing. Over allocation is only allowed for one thread at once in the driver. This allows us to restrict the amount of file metadata being materialized at once on the driver.

Accessed by the thread materializing files and by the thread releasing resources after execution.
