# Get data stream mappings

Authentication: required

Availability: Generally available since 9.1

## Paths

- `GET` `/_data_stream/{name}/_mappings`

#### Path parameters

- `name` (union string | string[]) — required
  A comma-separated list of data streams or data stream patterns. Supports wildcards (`*`).

## Description

Get mapping information for one or more data streams.

## Required privileges

- Index privileges: `view_index_metadata`

## Query string parameters

- `master_timeout` (union oneOf · default: 30s) — optional
  The period to wait for a connection to the master node. If no response is
received before the timeout expires, the request fails and returns an
error.
  Values: `-1`, `0`

## Response

      Map values (union oneOf)
      One of:
      - **type: binary** (`type: binary`)
        - `type` (enum)
          Values: `binary`
        - `meta` (map string to string)

        - `fields` (map string to oneOf) — recursive
        - `synthetic_source_keep` (enum)
          

Supported values include:
  - `none`: Synthetic source diverges from the original source (default)
  - `arrays`: Arrays of the corresponding field or object preserve the original element ordering and duplicate elements.
The synthetic source fragment for such arrays is not guaranteed to match the original source exactly,
e.g. array [1, 2, [5], [[4, [3]]], 5] may appear as-is or in an equivalent format like [1, 2, 5, 4, 3, 5].
The exact format may change in the future, in an effort to reduce the storage overhead of this option.
  - `all`: The source for both singleton instances and arrays of the corresponding field or object gets recorded.
When applied to objects, the source of all sub-objects and sub-fields gets captured.
Furthermore, the original source of arrays gets captured and appears in synthetic source with no modifications.
          Values: `none`, `arrays`, `all`

            - `multi_value` (boolean · default: true)
              If `false`, the field is treated as single-valued, enabling optimized storage.
Only has an effect when columnar index mode is active.
            - `nullability` (boolean · default: true)
              If `false`, every document must provide a non-null value for the field: a document that
omits the field, sets it to `null`, or supplies only null values (an empty array or an
all-null array) is rejected at index time.
A field that defines `null_value` is always exempt, since the configured default removes
the absence of a value.
Only has an effect when columnar index mode is active.

      - **type: match_only_text** (`type: match_only_text`)
        A variant of text that trades scoring and efficiency of positional queries for space efficiency. This field
effectively stores data the same way as a text field that only indexes documents (index_options: docs) and
disables norms (norms: false). Term queries perform as fast if not faster as on text fields, however queries
that need positions such as the match_phrase query perform slower as they need to look at the _source document
to verify whether a phrase matches. All queries return constant scores that are equal to 1.0.

that influence how the data structure is built. These can be adjusted to improve the accuracy of results, at the
expense of slower indexing speed.

This parameter can only be specified when `index` is `true`.
          - `confidence_interval` (number) — deprecated
            The confidence interval to use when quantizing the vectors. Can be any value between and including `0.90` and
`1.0` or exactly `0`. When the value is `0`, this indicates that dynamic quantiles should be calculated for
optimized quantization. When between `0.90` and `1.0`, this value restricts the values used when calculating
the quantization thresholds.

For example, a value of `0.95` will only use the middle `95%` of the values when calculating the quantization
thresholds (e.g. the highest and lowest `2.5%` of values will be ignored).

Defaults to `1/(dims + 1)` for `int8` quantized vectors and `0` for `int4` for dynamic quantile calculation.

Only applicable to `int8_hnsw`, `int4_hnsw`, `int8_flat`, and `int4_flat` index types.
          - `ef_construction` (number · default: 100)

          - `type` (enum)
            The type of kNN algorithm to use.

Supported values include:
  - `bbq_flat`: This utilizes a brute-force search algorithm in addition to automatically quantizing to binary vectors.
Only supports `element_type` of `float`.
  - `bbq_hnsw`: This utilizes the HNSW algorithm in addition to automatic binary quantization for scalable approximate kNN
search with `element_type` of `float`.

This can reduce the memory footprint by nearly 32x at the cost of some accuracy.
  - `bbq_disk`: This utilizes the DiskBBQ algorithm, a version of Inverted Vector File (IVF) that uses BBQ to quantize vectors.
Only supports `element_type` of `float`.

This not only significantly reduces memory usage, but also allows for indexing and searching of very large datasets that do not fit in memory.
Unlike HNSW, this index type loses performance gracefully as the index grows larger than memory.
  - `flat`: This utilizes a brute-force search algorithm for exact kNN search. This supports all `element_type` values.
  - `hnsw`: This utilizes the HNSW algorithm for scalable approximate kNN search. This supports all `element_type` values.
  - `int4_flat`: This utilizes a brute-force search algorithm in addition to automatically half-byte scalar quantization.
Only supports `element_type` of `float`.
  - `int4_hnsw`: This utilizes the HNSW algorithm in addition to automatically scalar quantization for scalable approximate kNN
search with `element_type` of `float`.

This can reduce the memory footprint by 8x at the cost of some accuracy.
  - `int8_flat`: This utilizes a brute-force search algorithm in addition to automatically scalar quantization. Only supports
`element_type` of `float`.
  - `int8_hnsw`: The default index type for `float` vectors. This utilizes the HNSW algorithm in addition to automatically scalar
quantization for scalable approximate kNN search with `element_type` of `float`.

This can reduce the memory footprint by 4x at the cost of some accuracy.
            Values: `bbq_flat`, `bbq_hnsw`, `bbq_disk`, `flat`, `hnsw`, `int4_flat`, `int4_hnsw`, `int8_flat`, `int8_hnsw`
          - `rescore_vector` (object)

            - `oversample` (number)
              The oversampling factor to use when searching for the nearest neighbor. This is only applicable to the quantized formats: `bbq_*`, `int4_*`, and `int8_*`.
When provided, `oversample * k` vectors will be gathered and then their scores will be re-computed with the original vectors.

valid values are between `1.0` and `10.0` (inclusive), or `0` exactly to disable oversampling.
          - `on_disk_rescore` (boolean · default: false)
            `true` if vector rescoring should be done on-disk

Only applicable to `bbq_disk`, `bbq_hnsw`, `int4_hnsw`, `int8_hnsw`
          - `flat_index_threshold` (number · default: -1)
            The segment document count threshold below which HNSW graph construction is skipped in favor of brute-force flat
search. `-1` (default) defers to format defaults: `300` for `bbq_hnsw`, `150` for `hnsw`, `int8_hnsw`, and
`int4_hnsw`. `0` always builds the graph. A positive value overrides the format default.

Only applicable to `hnsw`, `int8_hnsw`, `int4_hnsw`, `bbq_hnsw`, and `bbq_disk` index types.
          - `cluster_size` (number · default: 384)
            Only applicable to `bbq_disk`. The number of vectors per cluster. Must be between 64 and 65536.
          - `default_visit_percentage` (number · default: 0)
            Only applicable to `bbq_disk`. The percentage of clusters to visit during search. Must be between 0 and 100.
A value of 0 defaults to using `num_candidates` for calculating the visit percentage.
          - `bits` (number · default: 1)
            Only applicable to `bbq_disk`. The number of bits per dimension for quantization encoding.
Valid values are `1`, `2`, `4`, or `7`. When no `rescore_vector` is explicitly set,
the default oversampling is automatically adjusted based on the bits value.
This setting can be changed without reindexing.
          - `precondition` (boolean · default: false)
            Only applicable to `bbq_disk`. When `true`, transforms indexed vectors using a random orthogonal
projection before quantization, which can improve accuracy when vector components are not normally
distributed. Cannot be changed after the field is created.
          - `auto_calibrate` (boolean · default: false)
            Only applicable to `bbq_disk`. When `true`, Elasticsearch automatically selects the optimal
quantization encoding, oversampling factor, and preconditioning for each merged segment based
on estimated recall characteristics. Cannot be changed after the field is created.
        - `similarity` (enum)
          The vector similarity metric to use in kNN search.

Documents are ranked by their vector field's similarity to the query vector. The `_score` of each document will
be derived from the similarity, in a way that ensures scores are positive and that a larger score corresponds
to a higher ranking.

Defaults to `l2_norm` when `element_type` is `bit` otherwise defaults to `cosine`.

`bit` vectors only support `l2_norm` as their similarity metric.

This parameter can only be specified when `index` is `true`.

Supported values include:
  - `cosine`: Computes the cosine similarity. During indexing Elasticsearch automatically normalizes vectors with `cosine`
similarity to unit length. This allows to internally use `dot_product` for computing similarity, which is more
efficient. Original un-normalized vectors can be still accessed through scripts.

The document `_score` is computed as `(1 + cosine(query, vector)) / 2`.

The `cosine` similarity does not allow vectors with zero magnitude, since cosine is not defined in this case.
  - `dot_product`: Computes the dot product of two unit vectors. This option provides an optimized way to perform cosine similarity.
The constraints and computed score are defined by `element_type`.

When `element_type` is `float`, all vectors must be unit length, including both document and query vectors.

The document `_score` is computed as `(1 + dot_product(query, vector)) / 2`.

When `element_type` is `byte`, all vectors must have the same length including both document and query vectors or
results will be inaccurate.

The document `_score` is computed as `0.5 + (dot_product(query, vector) / (32768 * dims))` where `dims` is the
number of dimensions per vector.
  - `l2_norm`: Computes similarity based on the `L2` distance (also known as Euclidean distance) between the vectors.

The document `_score` is computed as `1 / (1 + l2_norm(query, vector)^2)`.

For `bit` vectors, instead of using `l2_norm`, the `hamming` distance between the vectors is used.

The `_score` transformation is `(numBits - hamming(a, b)) / numBits`.
  - `max_inner_product`: Computes the maximum inner product of two vectors. This is similar to `dot_product`, but doesn't require vectors
to be normalized. This means that each vector’s magnitude can significantly effect the score.

The document `_score` is adjusted to prevent negative values. For `max_inner_product` values `< 0`, the `_score`
is `1 / (1 + -1 * max_inner_product(query, vector))`. For non-negative `max_inner_product` results the `_score`
is calculated `max_inner_product(query, vector) + 1`.

              Only applicable to the `recursive` strategy and required when using it.

A list of strings used as possible split points when chunking text.

Each string can be a plain string or a regular expression (regex) pattern.
The system tries each separator in order to split the text, starting from the first item in the list.

After splitting, it attempts to recombine smaller pieces into larger chunks that stay within
the `max_chunk_size` limit, to reduce the total number of chunks generated.
