Speedup PBS restore by fetching chunks concurrently using a configurable
number of threads. 4 threads are used by default, the environment
variable PBS_RESTORE_CONCURRENCY should be between 1 and 32 inclusive.
The upper limit is max_blocking_threads in BackupClient.
Adam Kalisz (1):
Make retrieval of chunks concurrent when restoring backup, add more
statistics on chunk fetching and writing to storage. Allow
configuring the number of threads fetching chunks using
PBS_RESTORE_CONCURRENCY environment variable.
