• #2451 Small Performance improvements

5.0.0

GA release of NEST and Elasticsearch.Net 5.0 🎉

A huge thank you to the community who kicked the tires on the 5.0 prereleases that we've been putting out since April and provided us with invaluable feedback 🖖

Check out the blog post on the NEST 5.0 release that highlights some of the main features as well as take a look at the 2.x -> 5.x Breaking Changes for NEST and Breaking Changes for Elasticsearch.Net.

Features

• #2454 Add Support for CreateRequest<T>. This can be used to create a document of a given type in a given index with a given id, with optimistic concurrency control. See https://www.elastic.co/guide/en/elasticsearch/reference/master/docs-index_.html#operation-type for more details
• #2443 Add ScrollAll() helper method

Enhancements

• #2473 Limit the number of concurrent connections on .NET Core, similar to Desktop CLR.

• #2457 Use IndexName and TypeName types for Bulk*Many requests

• #2459 Add type to set index auto expand replica setting

• #2450 Add metadata for Security roles

• #2462 ReindexAll() improvements

  ReindexAll() is now composed over the IObservables from ScrollAll() and BulkAll(), taking advantage of the concurrency models in each.

  Since the rate at which the scrolls produces far exceeds the rate at which we can consume them through bulks ReindexAll() also implements a producer/consumer rate limiter. This is controlled by a backPressureFactor which controls the max amplification factor of running scrolls with the safe guard of:

  searchSize * maxConcurrency * backPressureFactor >= bulkSize

• #2451 Small Performance improvements

  Introduce a BufferSize property on JsonNetSerializer with a default size of 1024 to use when writing json to the request stream. Performance tests as part of #1899 indicate this to be a good compromise buffer size for performance throughput and bytes allocated.

• #2480 Allow target document type to be different from source document type when performing reindex

Bug fixes

• #2479 Deserialize "value_as_string" for metric aggregations that return it
• #2466 Deserialize attachment title when deserializing an Attachment type from _source or field data
• #2464 Add the StringEnumConverter to StringFielddataFormat to always serialize as string. Introduce coding standard unit test to assert the converter is applied to all NEST enums
• #2468 Favour publish_address when sniffing cluster state
• #2467 Fix the virality of &= in the bool query DSL

Misc

• #2456 Tidy up TODOs and #2460 make the usage of NotSupportedException consistent across all internal JsonConverter types.
• #2470 Add test collection filtering when running tests from the command line.

• #2418 Faster enum to string resolution

• #2420 Fix the way in which HttpClient are created when using the HttpConnection on .NET Core. A HttpClient was created based on a hashcode of RequestData that included a regression bug that caused multiple instances of HttpClient to be created. Now, for RequestData where

  • RequestTimeout
  • HttpCompression
  • ProxyAddress
  • ProxyUsername
  • ProxyPassword
  • DisableAutomaticProxyDetection

  do not change, the same HttpClient instance will be used

• #2428 Add specific type for term vectors in MutliTermVectorsResponse instead of reusing TermVectorsResponse

• #2440 Ensure that each part of the async pipeline for Desktop CLR HttpConnection can be cancelled correctly

Deprecations and Removals

• #1958 Allow exceptions late in the pipeline to bubble out as UnexpectedElasticsearchClientException e.g. ResolveException that can happen within the transport when serializing to json.

5.0.0-rc3

Bug Fixes

• #2412 Fix a number of dictionary serialization issues

A recent change did not handle a number of dictionary serialization cases including

• types that implement IReadOnlyDictionary<TKey,TValue>

  e.g. public class MyReadOnlyDictionary<TKey,TValue> : IReadOnlyDictionary<TKey,TValue>

• types that implement IDictionary<TKey, TValue>

  e.g. public class MyDictionary<TKey,TValue> : IDictionary<TKey,TValue>

• non-generic types that inherit a closed generic dictionary type

  e.g. public class MyDictionary : Dictionary<string,object>

• types that implement IDictionary that are not generic

  e.g. public class MyNonGenericDictionary : IDictionary
