Class ElasticsearchIndexSettings

java.lang.Object
org.hibernate.search.backend.elasticsearch.cfg.ElasticsearchIndexSettings
public final class ElasticsearchIndexSettings extends Object
Configuration properties for Elasticsearch indexes.

Constants in this class are to be appended to a prefix to form a property key; see IndexSettings for details.

  • Field Details

    • ANALYSIS_CONFIGURER

      public static final String ANALYSIS_CONFIGURER
      The analysis configurer applied to this index.

      Expects a single-valued or multi-valued reference to beans of type ElasticsearchAnalysisConfigurer.

      Defaults to no value.

      See Also:

    • SCHEMA_MANAGEMENT_MINIMAL_REQUIRED_STATUS

      public static final String SCHEMA_MANAGEMENT_MINIMAL_REQUIRED_STATUS
      The minimal required status of an index on startup, before Hibernate Search can start using it.

      Expects an IndexStatus value, or a String representation of such value.

      Defaults to ElasticsearchIndexSettings.Defaults.SCHEMA_MANAGEMENT_MINIMAL_REQUIRED_STATUS.

      See Also:

    • SCHEMA_MANAGEMENT_MINIMAL_REQUIRED_STATUS_WAIT_TIMEOUT

      public static final String SCHEMA_MANAGEMENT_MINIMAL_REQUIRED_STATUS_WAIT_TIMEOUT
      The timeout when waiting for the required status.

      Expects a positive Integer value in milliseconds, such as 60000, or a String that can be parsed into such Integer value.

      Defaults to ElasticsearchIndexSettings.Defaults.SCHEMA_MANAGEMENT_MINIMAL_REQUIRED_STATUS_WAIT_TIMEOUT.

      See Also:

    • SCHEMA_MANAGEMENT_SETTINGS_FILE

      public static final String SCHEMA_MANAGEMENT_SETTINGS_FILE
      The path to a settings file, allowing to add custom settings to indexes created by Hibernate Search as part of schema management.

      Expects a string representing the path to a file in the classpath, encoded in UTF-8. The file must contain index settings expressed in JSON format, with the exact same syntax as expected by the Elasticsearch server under the "settings" property when creating an index. For example, if the file content is {"index.codec": "best_compression"}, it will set index.codec to best_compression.

      Note that the settings generated by Hibernate Search will be overridden in case of conflict of some definitions. For instance, if an analyzer "myAnalyzer" is defined by the ANALYSIS_CONFIGURER and this settings file, the definition from the settings file will win. If it is only defined in either the analysis configurer or the settings file, but not both, it will be preserved as-is.

      Defaults to no value. Because by default index settings are generated by Hibernate Search.

      See Also:

    • SCHEMA_MANAGEMENT_MAPPING_FILE

      public static final String SCHEMA_MANAGEMENT_MAPPING_FILE
      The path to a mappings file, allowing to add custom mappings to indexes created by Hibernate Search as part of schema management.

      Expects a string representing the path to a file in the classpath, encoded in UTF-8. The file must contain index settings expressed in JSON format, with the exact same syntax as expected by the Elasticsearch server under the "mappings" property when defining the mapping for an index.

      The file does not need to contain the full mapping: Hibernate Search will automatically inject missing properties (index fields) in the given mapping.

      Conflicts between the given mapping and the mapping generated by Hibernate Search will be handled as follows:

      • Mapping parameters other than properties at the mapping root will be those from the given mapping; those generated by Hibernate Search will be ignored.
      • properties will be merged, using properties defined in both the given mapping and the mapping generated by Hibernate Search. If a property is defined on both sides, mapping parameters from the given mapping will be used, except for properties, which will be merged recursively in the same way.

      Defaults to no value. Because by default index mappings are generated by Hibernate Search.

      See Also:

    • DYNAMIC_MAPPING

      public static final String DYNAMIC_MAPPING
      Specify the default behavior to handle dynamically-mapped fields in the Elasticsearch mapping.

      Defaults to ElasticsearchIndexSettings.Defaults.DYNAMIC_MAPPING.

      In case of dynamic fields with field templates, the value will be ignored, since this feature requires a DynamicMapping.TRUE to operate.

      See Also:

    • INDEXING_PREFIX

      public static final String INDEXING_PREFIX
      The prefix for indexing-related property keys.
      See Also:

    • INDEXING_QUEUE_COUNT

      public static final String INDEXING_QUEUE_COUNT
      The number of indexing queues assigned to each index.

      Expects a strictly positive integer value, or a string that can be parsed to such integer value.

      Defaults to ElasticsearchIndexSettings.Defaults.INDEXING_QUEUE_COUNT.

      See the reference documentation, section "Elasticsearch backend - Indexing", for more information about this setting and its implications.

      See Also:

    • INDEXING_QUEUE_SIZE

      public static final String INDEXING_QUEUE_SIZE
      The size of indexing queues.

      Expects a strictly positive integer value, or a string that can be parsed to such integer value.

      Defaults to ElasticsearchIndexSettings.Defaults.INDEXING_QUEUE_SIZE.

      See the reference documentation, section "Elasticsearch backend - Indexing", for more information about this setting and its implications.

      See Also:

    • INDEXING_MAX_BULK_SIZE

      public static final String INDEXING_MAX_BULK_SIZE
      The maximum size of bulk requests created when processing indexing queues.

      Expects a strictly positive integer value, or a string that can be parsed to such integer value.

      Defaults to ElasticsearchIndexSettings.Defaults.INDEXING_MAX_BULK_SIZE.

      See the reference documentation, section "Elasticsearch backend - Indexing", for more information about this setting and its implications.
