blob_storage_config

The blob_storage_config section specifies a static cluster group's configuration. A static group is necessary for the operation of the basic cluster tablets, including Hive, SchemeShard, and BlobstorageController. As a rule, these tablets do not store a lot of data, so we don't recommend creating more than one static group.

For a static group, specify the disks and nodes that the static group will be placed on. For example, a configuration for the erasure: none model can be as follows:

blob_storage_config:
  service_set:
    groups:
    - erasure_species: none
      rings:
      - fail_domains:
        - vdisk_locations:
          - node_id: 1
            path: /dev/disk/by-partlabel/ydb_disk_ssd_02
            pdisk_category: SSD
....

For a configuration located in 3 availability zones, specify 3 rings. For a configuration within a single availability zone, specify exactly one ring.
