DefaultReplication: 2
- # Lifetime (in seconds) of blob permission signatures generated by
- # the API server. This determines how long a client can take (after
- # retrieving a collection record) to retrieve the collection data
- # from Keep. If the client needs more time than that (assuming the
- # collection still has the same content and the relevant user/token
- # still has permission) the client can retrieve the collection again
- # to get fresh signatures.
+ # BlobSigningTTL determines the minimum lifetime of transient
+ # data, i.e., blocks that are not referenced by
+ # collections. Unreferenced blocks exist for two reasons:
+ #
+ # 1) A data block must be written to a disk/cloud backend device
+ # before a collection can be created/updated with a reference to
+ # it.
+ #
+ # 2) Deleting or updating a collection can remove the last
+ # remaining reference to a data block.
+ #
+ # If BlobSigningTTL is too short, long-running
+ # processes/containers will fail when they take too long (a)
+ # between writing blocks and writing collections that reference
+ # them, or (b) between reading collections and reading the
+ # referenced blocks.
+ #
+ # If BlobSigningTTL is too long, data will still be stored long
+ # after the referring collections are deleted, and you will
+ # needlessly fill up disks or waste money on cloud storage.
#
# Modifying BlobSigningTTL invalidates existing signatures; see
# BlobSigningKey note above.
