One second is always composed of 1000ms. This allows fixed intervals to be specified in any multiple of the supported units.\nHowever, it means fixed intervals cannot express other units such as months, since the duration of a month is not a fixed quantity. Attempting to specify a calendar interval like month or quarter will throw an exception.\nThe accepted units for fixed intervals are:\n milliseconds (ms)\nA single millisecond. This is a very, very small interval. seconds (s)\nDefined as 1000 milliseconds each. minutes (m)\nDefined as 60 seconds each (60,000 milliseconds). All minutes begin at 00 seconds. hours (h)\nDefined as 60 minutes each (3,600,000 milliseconds). All hours begin at 00 minutes and 00 seconds. days (d)\nDefined as 24 hours (86,400,000 milliseconds).

Our mission is to deliver real-time smart search experiences tailored for enterprises by fully harnessing the potential of modern hardware and the AI capability. We are committed to meeting the demands of high concurrency and high throughput in challenging environments, all while providing seamless and efficient search capabilities.\nFeatures #   The Next-Gen Real-Time Search \u0026amp; AI-Native Innovation Engine Written in Rust.\n Major Features of Pizza:\n True Real-Time, get search results instantly after insertion, no need to refresh anymore. Support partial update in place, no longer pull and push back the entire document again. High performance, lightning fast with high throughput and low latency, hardware reduced. High scalability, supports very large-scale clusters, beyond petabytes. Native integration with LLMs and ML, empowering AI-Native enterprise innovation. Design with storage and computation separation, and also storage and index separation.  Architecture #  -- Pizza is building on top of these awesome projects:\n  Rust  Apache Arrow  Arrow DataFusion  Why Pizza #  The name Pizza was taken from our unique sharding design.\nThe documents in Pizza are persisted as Parquet files in object storage. Native integration with other big data systems through object storage and the standard Parquet format.\nWhen to use Pizza #  Pizza is good fit when:\n You have latency-sensitive search applications that millisecond matters. You need fresh data, your data is mutable, and you need fast queries. You need to handle high concurrency with complex queries. You need to handle more than petabytes data for user-facing use cases. You need to handle JOIN for complex data relations. You need to keep thousands of fields, but only a handful are subject to change. You need to manage both structured and unstructured data in a cohesive manner.  Pizza is designed to address these problems at heart, to solve real critical business issues, serve your data-driven applications in realtime at very large scale. Enhance and enrich the data experiences of your end-users.\nDesign choices #  The philosophy of Pizza is that indexes should be designed per use case, and should not attempt to fit every use case with a single index. Therefore, we introduced Views, which allow combining different document sources into a single index or separating a document into different layers of indexes for different use cases.\nBy emphasizes the decoupling of storage and computation, as well as the separation of storage and indexing. Which enables efficient and scalable data processing by allowing independent management and optimization of storage resources, computational resources, and indexing strategies.\nNative integration with LLMs (Language Models) and ML (Machine Learning) technologies is a key aspect of Pizza, providing powerful capabilities for AI-Native enterprise innovation. By seamlessly integrating with LLMs and ML frameworks, Pizza enables advanced natural language processing, machine learning, and data analytics directly within the search and data retrieval pipeline.\nWe are in the process of building the next-generation search infrastructure, driven by our unwavering commitment to delivering real-time search experiences for enterprises, unlocking the potential of modern hardware, and catering to the demands of high concurrency and high throughput in the most challenging of environments\nNext step #   Install and configure Pizza.\n"});index.add({'id':12,'href':'/docs/references/aggregation/percentiles/','title':"Percentiles aggregation",'section':"Aggregation",'content':"Percentiles aggregation #  A multi-value metrics aggregation that calculates one or more percentiles over numeric values extracted from the aggregated documents.\nPercentiles show the point at which a certain percentage of observed values occur. For example, the 95th percentile is the value which is greater than 95% of the observed values.\nPercentiles are often used to find outliers. In normal distributions, the 0.13th and 99.87th percentiles represents three standard deviations from the mean. Any data which falls outside three standard deviations is often considered an anomaly.\nWhen a range of percentiles are retrieved, they can be used to estimate the data distribution and determine if the data is skewed, bimodal, etc.\nExamples #  Assume your data consists of website load times. The average and median load times are not overly useful to an administrator. The max may be interesting, but it can be easily skewed by a single slow response.\nLet\u0026rsquo;s look at a range of percentiles representing load time:\nPOST latency/_search { \u0026#34;aggs\u0026#34;: { \u0026#34;load_time_outlier\u0026#34;: { \u0026#34;percentiles\u0026#34;: { \u0026#34;field\u0026#34;: \u0026#34;load_time\u0026#34; } } } } By default, the percentile metric will generate a range of percentiles: [1, 5, 25, 50, 75, 95, 99]. The response will look like this:\n{ ... \u0026#34;aggregations\u0026#34;: { \u0026#34;load_time_outlier\u0026#34;: { \u0026#34;values\u0026#34;: { \u0026#34;1.0\u0026#34;: 10.0, \u0026#34;5.0\u0026#34;: 30.0, \u0026#34;25.0\u0026#34;: 170.0, \u0026#34;50.0\u0026#34;: 445.0, \u0026#34;75.0\u0026#34;: 720.0, \u0026#34;95.0\u0026#34;: 940.0, \u0026#34;99.0\u0026#34;: 980.0 } } } } As you can see, the aggregation will return a calculated value for each percentile in the default range. If we assume response times are in milliseconds, it is immediately obvious that the webpage normally loads in 10-725ms, but occasionally spikes to 945-985ms.\nOften, administrators are only interested in outliers — the extreme percentiles. We can specify just the percents we are interested in (requested percentiles must be a value between 0-100 inclusive):\nPOST latency/_search { \u0026#34;aggs\u0026#34;: { \u0026#34;load_time_outlier\u0026#34;: { \u0026#34;percentiles\u0026#34;: { \u0026#34;field\u0026#34;: \u0026#34;load_time\u0026#34;, \u0026#34;percents\u0026#34;: [95, 99, 99.9] } } } } Parameters for avg #   field\n(Required, string) Field you wish to aggregate. percents\n(Optional, array) A range of percentiles that are calculated.
