   # Storage
   # =======
   # Fluent Bit can use memory and filesystem buffering based mechanisms
   #
   # - https://docs.fluentbit.io/manual/administration/buffering-and-storage
   #
   # storage metrics
   # ---------------
   # publish storage pipeline metrics in '/api/v1/storage'. The metrics are
   # exported only if the 'http_server' option is enabled.
   #
   storage.metrics on

   # storage.path
   # ------------
   # absolute file system path to store filesystem data buffers (chunks).
   #
   # storage.path /tmp/storage

   # storage.sync
   # ------------
   # configure the synchronization mode used to store the data into the
   # filesystem. It can take the values normal or full.
   #
   # storage.sync normal

   # storage.checksum
   # ----------------
   # enable the data integrity check when writing and reading data from the
   # filesystem. The storage layer uses the CRC32 algorithm.
   #
   # storage.checksum off

   # storage.backlog.mem_limit
   # -------------------------
   # if storage.path is set, Fluent Bit will look for data chunks that were
   # not delivered and are still in the storage layer, these are called
   # backlog data. This option configure a hint of maximum value of memory
   # to use when processing these records.
   #
   # storage.backlog.mem_limit 5M
