org.elasticsearch.index.IndexSettings
public final class IndexSettings extends Object
This class encapsulates all index level settings and handles settings updates. It's created per index and available to all index level classes and allows them to retrieve the latest updated settings instance. Classes that need to listen to settings updates can register a settings consumer at index creation via IndexModule.addSettingsUpdateConsumer(Setting, Consumer) that will be called for each settings update.

      public static final Setting<Boolean> INDEX_WARMER_ENABLED_SETTING

    • INDEX_CHECK_ON_STARTUP

      public static final Setting<String> INDEX_CHECK_ON_STARTUP

    • MAX_RESULT_WINDOW_SETTING

      public static final Setting<Integer> MAX_RESULT_WINDOW_SETTING
      Index setting describing the maximum value of from + size on a query. The Default maximum value of from + size on a query is 10,000. This was chosen as a conservative default as it is sure to not cause trouble. Users can certainly profile their cluster and decide to set it to 100,000 safely. 1,000,000 is probably way to high for any cluster to set safely.

    • MAX_INNER_RESULT_WINDOW_SETTING

      public static final Setting<Integer> MAX_INNER_RESULT_WINDOW_SETTING
      Index setting describing the maximum value of from + size on an individual inner hit definition or top hits aggregation. The default maximum of 100 is defensive for the reason that the number of inner hit responses and number of top hits buckets returned is unbounded. Profile your cluster when increasing this setting.

    • MAX_SCRIPT_FIELDS_SETTING

      public static final Setting<Integer> MAX_SCRIPT_FIELDS_SETTING
      Index setting describing the maximum value of allowed `script_fields`that can be retrieved per search request. The default maximum of 32 is defensive for the reason that retrieving script fields is a costly operation.

    • MAX_TOKEN_COUNT_SETTING

      public static final Setting<Integer> MAX_TOKEN_COUNT_SETTING
      A setting describing the maximum number of tokens that can be produced using _analyze API. The default maximum of 10000 is defensive to prevent generating too many token objects.

    • MAX_ANALYZED_OFFSET_SETTING

      public static final Setting<Integer> MAX_ANALYZED_OFFSET_SETTING
      A setting describing the maximum number of characters that will be analyzed for a highlight request. This setting is only applicable when highlighting is requested on a text that was indexed without offsets or term vectors. The default maximum of 1M characters is defensive as for highlighting larger texts, indexing with offsets or term vectors is recommended.

    • WEIGHT_MATCHES_MODE_ENABLED_SETTING

      public static final Setting<Boolean> WEIGHT_MATCHES_MODE_ENABLED_SETTING
      Index setting to enable/disable the UnifiedHighlighter.HighlightFlag.WEIGHT_MATCHES mode of the unified highlighter.

    • MAX_TERMS_COUNT_SETTING

      public static final Setting<Integer> MAX_TERMS_COUNT_SETTING
      Index setting describing the maximum number of terms that can be used in Terms Query. The default maximum of 65536 terms is defensive, as extra processing and memory is involved for each additional term, and a large number of terms degrade the cluster performance.

    • MAX_NGRAM_DIFF_SETTING

      public static final Setting<Integer> MAX_NGRAM_DIFF_SETTING
      Index setting describing for NGramTokenizer and NGramTokenFilter the maximum difference between max_gram (maximum length of characters in a gram) and min_gram (minimum length of characters in a gram). The default value is 1 as this is default difference in NGramTokenizer, and is defensive as it prevents generating too many index terms.

    • MAX_SHINGLE_DIFF_SETTING

      public static final Setting<Integer> MAX_SHINGLE_DIFF_SETTING
      Index setting describing for ShingleTokenFilter the maximum difference between max_shingle_size and min_shingle_size. The default value is 3 is defensive as it prevents generating too many tokens.

    • MAX_DOCVALUE_FIELDS_SEARCH_SETTING

      public static final Setting<Integer> MAX_DOCVALUE_FIELDS_SEARCH_SETTING
      Index setting describing the maximum value of allowed `docvalue_fields`that can be retrieved per search request. The default maximum of 100 is defensive for the reason that retrieving doc values might incur a per-field per-document seek.

    • MAX_RESCORE_WINDOW_SETTING

      public static final Setting<Integer> MAX_RESCORE_WINDOW_SETTING
      Index setting describing the maximum size of the rescore window. Defaults to MAX_RESULT_WINDOW_SETTING because they both do the same thing: control the size of the heap of hits.

    • INDEX_TRANSLOG_GENERATION_THRESHOLD_SIZE_SETTING

      public static final Setting<ByteSizeValue> INDEX_TRANSLOG_GENERATION_THRESHOLD_SIZE_SETTING
      The maximum size of a translog generation. This is independent of the maximum size of translog operations that have not been flushed.

    • DEFAULT_GC_DELETES

      public static final TimeValue DEFAULT_GC_DELETES
      Index setting to enable / disable deletes garbage collection. This setting is realtime updateable

    • INDEX_GC_DELETES_SETTING

      public static final Setting<TimeValue> INDEX_GC_DELETES_SETTING

    • INDEX_SOFT_DELETES_SETTING

      public static final Setting<Boolean> INDEX_SOFT_DELETES_SETTING
      Specifies if the index should use soft-delete instead of hard-delete for update/delete operations. Soft-deletes is enabled by default for 7.0 indices and mandatory for 8.0 indices.

    • INDEX_SOFT_DELETES_RETENTION_OPERATIONS_SETTING

      public static final Setting<Long> INDEX_SOFT_DELETES_RETENTION_OPERATIONS_SETTING
      Controls how many soft-deleted documents will be kept around before being merged away. Keeping more deleted documents increases the chance of operation-based recoveries and allows querying a longer history of documents. If soft-deletes is enabled, an engine by default will retain all operations up to the global checkpoint.

    • INDEX_TRANSLOG_RETENTION_AGE_SETTING

      public static final Setting<TimeValue> INDEX_TRANSLOG_RETENTION_AGE_SETTING
      Controls how long translog files that are no longer needed for persistence reasons will be kept around before being deleted. Keeping more files is useful to increase the chance of ops based recoveries for indices with soft-deletes disabled. TODO: Remove this setting in 9.0.

    • INDEX_TRANSLOG_RETENTION_SIZE_SETTING

      public static final Setting<ByteSizeValue> INDEX_TRANSLOG_RETENTION_SIZE_SETTING
      Controls how many translog files that are no longer needed for persistence reasons will be kept around before being deleted. Keeping more files is useful to increase the chance of ops based recoveries for indices with soft-deletes disabled. TODO: Remove this setting in 9.0.

    • INDEX_SOFT_DELETES_RETENTION_LEASE_PERIOD_SETTING

      public static final Setting<TimeValue> INDEX_SOFT_DELETES_RETENTION_LEASE_PERIOD_SETTING
      Controls the maximum length of time since a retention lease is created or renewed before it is considered expired.

    • MAX_REFRESH_LISTENERS_PER_SHARD

    • FILE_BASED_RECOVERY_THRESHOLD_SETTING

      public static final Setting<Double> FILE_BASED_RECOVERY_THRESHOLD_SETTING
      Determines a balance between file-based and operations-based peer recoveries. The number of operations that will be used in an operations-based peer recovery is limited to this proportion of the total number of documents in the shard (including deleted documents) on the grounds that a file-based peer recovery may copy all of the documents in the shard over to the new peer, but is significantly faster than replaying the missing operations on the peer, so once a peer falls far enough behind the primary it makes more sense to copy all the data over again instead of replaying history. Defaults to retaining history for up to 10% of the documents in the shard. This can only be changed in tests, since this setting is intentionally unregistered.

    • BLOOM_FILTER_ID_FIELD_ENABLED_SETTING

      public static final Setting<Boolean> BLOOM_FILTER_ID_FIELD_ENABLED_SETTING
      This index setting is intentionally undocumented and should be used as an escape hatch to disable BloomFilter of the _id field of non-data-stream indices, which is enabled by default. This setting doesn't affect data-stream indices.

      The "mode" of the index.

    • MAX_ADJACENCY_MATRIX_FILTERS_SETTING

      @Deprecated public static final Setting<Integer> MAX_ADJACENCY_MATRIX_FILTERS_SETTING
      Deprecated.
      Legacy index setting, kept for 7.x BWC compatibility. This setting has no effect in 8.x. Do not use. TODO: Remove in 9.0

    • IGNORE_ABOVE_SETTING

      public static final Setting<Integer> IGNORE_ABOVE_SETTING
      The `index.mapping.ignore_above` setting defines the maximum length for the content of a field that will be indexed or stored. If the length of the field’s content exceeds this limit, the field value will be ignored during indexing. This setting is useful for `keyword`, `flattened`, and `wildcard` fields where very large values are undesirable. It allows users to manage the size of indexed data by skipping fields with excessively long content. As an index-level setting, it applies to all `keyword` and `wildcard` fields, as well as to keyword values within `flattened` fields. When it comes to arrays, the `ignore_above` setting applies individually to each element of the array. If any element's length exceeds the specified limit, only that element will be ignored during indexing, while the rest of the array will still be processed. This behavior is consistent with the field-level `ignore_above` setting. This setting can be overridden at the field level by specifying a custom `ignore_above` value in the field mapping.

      Example usage: 

       "index.mapping.ignore_above": 256

      NOTE: The value for `ignore_above` is the _character count_, but Lucene counts bytes. Here we set the limit to `32766 / 4 = 8191` since UTF-8 characters may occupy at most 4 bytes.
