    • aggregations

      public final DatafeedConfig.Builder aggregations​(java.util.Map<java.lang.String,​Aggregation> map)
      If set, the datafeed performs aggregation searches. Support for aggregations is limited and should be used only with low cardinality data.

      API name: aggregations

      Adds all entries of map to aggregations.

    • aggregations

      public final DatafeedConfig.Builder aggregations​(java.lang.String key, Aggregation value)
      If set, the datafeed performs aggregation searches. Support for aggregations is limited and should be used only with low cardinality data.

      API name: aggregations

      Adds an entry to aggregations.

    • aggregations

      public final DatafeedConfig.Builder aggregations​(java.lang.String key, java.util.function.Function<Aggregation.Builder,​ObjectBuilder<Aggregation>> fn)
      If set, the datafeed performs aggregation searches. Support for aggregations is limited and should be used only with low cardinality data.

      API name: aggregations

      Adds an entry to aggregations using a builder lambda.

    • chunkingConfig

      public final DatafeedConfig.Builder chunkingConfig​(@Nullable ChunkingConfig value)
      Datafeeds might be required to search over long time periods, for several months or years. This search is split into time chunks in order to ensure the load on Elasticsearch is managed. Chunking configuration controls how the size of these time chunks are calculated and is an advanced configuration option.

      API name: chunking_config

    • chunkingConfig

      public final DatafeedConfig.Builder chunkingConfig​(java.util.function.Function<ChunkingConfig.Builder,​ObjectBuilder<ChunkingConfig>> fn)
      Datafeeds might be required to search over long time periods, for several months or years. This search is split into time chunks in order to ensure the load on Elasticsearch is managed. Chunking configuration controls how the size of these time chunks are calculated and is an advanced configuration option.

      API name: chunking_config

    • datafeedId

      public final DatafeedConfig.Builder datafeedId​(@Nullable java.lang.String value)
      A numerical character string that uniquely identifies the datafeed. This identifier can contain lowercase alphanumeric characters (a-z and 0-9), hyphens, and underscores. It must start and end with alphanumeric characters.

      API name: datafeed_id

    • delayedDataCheckConfig

      public final DatafeedConfig.Builder delayedDataCheckConfig​(@Nullable DelayedDataCheckConfig value)
      Specifies whether the datafeed checks for missing data and the size of the window. The datafeed can optionally search over indices that have already been read in an effort to determine whether any data has subsequently been added to the index. If missing data is found, it is a good indication that the query_delay option is set too low and the data is being indexed after the datafeed has passed that moment in time. This check runs only on real-time datafeeds.

      API name: delayed_data_check_config

    • delayedDataCheckConfig

      public final DatafeedConfig.Builder delayedDataCheckConfig​(java.util.function.Function<DelayedDataCheckConfig.Builder,​ObjectBuilder<DelayedDataCheckConfig>> fn)
      Specifies whether the datafeed checks for missing data and the size of the window. The datafeed can optionally search over indices that have already been read in an effort to determine whether any data has subsequently been added to the index. If missing data is found, it is a good indication that the query_delay option is set too low and the data is being indexed after the datafeed has passed that moment in time. This check runs only on real-time datafeeds.

      API name: delayed_data_check_config

    • frequency

      public final DatafeedConfig.Builder frequency​(@Nullable java.lang.String value)
      The interval at which scheduled queries are made while the datafeed runs in real time. The default value is either the bucket span for short bucket spans, or, for longer bucket spans, a sensible fraction of the bucket span. For example: 150s. When frequency is shorter than the bucket span, interim results for the last (partial) bucket are written then eventually overwritten by the full bucket results. If the datafeed uses aggregations, this value must be divisible by the interval of the date histogram aggregation.

      API name: frequency

    • indexes

      public final DatafeedConfig.Builder indexes​(java.util.List<java.lang.String> list)
      API name: indexes

      API name: indices

      Adds one or more values to indices.

    • indicesOptions

      public final DatafeedConfig.Builder indicesOptions​(@Nullable IndicesOptions value)
      Specifies index expansion options that are used during search.

      API name: indices_options

    • indicesOptions

      public final DatafeedConfig.Builder indicesOptions​(java.util.function.Function<IndicesOptions.Builder,​ObjectBuilder<IndicesOptions>> fn)
      Specifies index expansion options that are used during search.

      API name: indices_options

    • jobId

      public final DatafeedConfig.Builder jobId​(@Nullable java.lang.String value)
      API name: job_id

    • maxEmptySearches

      public final DatafeedConfig.Builder maxEmptySearches​(@Nullable java.lang.Integer value)
      If a real-time datafeed has never seen any data (including during any initial training period) then it will automatically stop itself and close its associated job after this many real-time searches that return no documents. In other words, it will stop after frequency times max_empty_searches of real-time operation. If not set then a datafeed with no end time that sees no data will remain started until it is explicitly stopped.

      API name: max_empty_searches

    • query

      public final DatafeedConfig.Builder query​(Query value)
      Required - The Elasticsearch query domain-specific language (DSL). This value corresponds to the query object in an Elasticsearch search POST body. All the options that are supported by Elasticsearch can be used, as this object is passed verbatim to Elasticsearch.

      API name: query

    • query

      public final DatafeedConfig.Builder query​(java.util.function.Function<Query.Builder,​ObjectBuilder<Query>> fn)
      Required - The Elasticsearch query domain-specific language (DSL). This value corresponds to the query object in an Elasticsearch search POST body. All the options that are supported by Elasticsearch can be used, as this object is passed verbatim to Elasticsearch.

      API name: query

    • queryDelay

      public final DatafeedConfig.Builder queryDelay​(@Nullable java.lang.String value)
      The number of seconds behind real time that data is queried. For example, if data from 10:04 a.m. might not be searchable in Elasticsearch until 10:06 a.m., set this property to 120 seconds. The default value is randomly selected between 60s and 120s. This randomness improves the query performance when there are multiple jobs running on the same node.

      API name: query_delay
