  limit
  
  ignore_dynamic_beyond_limit
  
  depth object
  
  Hide depth attribute Show depth attribute object
  
  limit number
  
  The maximum depth for a field, which is measured as the number of inner objects. For instance, if all fields are defined at the root object level, then the depth is 1. If there is one object mapping, then the depth is 2, etc.
  
  nested_fields object
  
  Hide nested_fields attribute Show nested_fields attribute object
  
  limit number
  
  The maximum number of distinct nested mappings in an index. The nested type should only be used in special cases, when arrays of objects need to be queried independently of each other. To safeguard against poorly designed mappings, this setting limits the number of unique nested types per index.
  
  nested_objects object
  
  Hide nested_objects attribute Show nested_objects attribute object
  
  limit number
  
  The maximum number of nested JSON objects that a single document can contain across all nested types. This limit helps to prevent out of memory errors when a document contains too many nested objects.
  
  field_name_length object
  
  Hide field_name_length attribute Show field_name_length attribute object
  
  limit number
  
  Setting for the maximum length of a field name. This setting isn’t really something that addresses mappings explosion but might still be useful if you want to limit the field length. It usually shouldn’t be necessary to set this setting. The default is okay unless a user starts to add a huge number of fields with really long names. Default is Long.MAX_VALUE (no limit).
  
  dimension_fields object
  
  Hide dimension_fields attribute Show dimension_fields attribute object
  
  limit number

  memory object Required
  
  Hide memory attribute Show memory attribute object
  
  limit number
  
  Number of outstanding bytes that may be consumed by indexing requests. When this limit is reached or exceeded, the node will reject new coordinating and primary operations. When replica operations consume 1.5x this limit, the node will reject new replica operations. Defaults to 10% of the heap.
  
  store object
  
  Hide store attributes Show store attributes object
  
  type string Required
  
  Any of:
  StorageType string StorageType string
  
  Values are fs, niofs, mmapfs, or hybridfs.
  
  allow_mmap boolean
  
  You can restrict the use of the mmapfs and the related hybridfs store type via the setting node.store.allow_mmap. This is a boolean setting indicating whether or not memory-mapping is allowed. The default is to allow it. This setting is useful, for example, if you are in an environment where you can not control the ability to create a lot of memory maps so you need disable the ability to use memory-mapping.
  
  status string Required
  
  Values are green, GREEN, yellow, YELLOW, red, or RED.
  
  system boolean Generally available; Added in 7.10.0
  
  If true, the data stream is created and managed by an Elastic stack component and cannot be modified through normal user interaction.
