Elasticsearch.Net breaking changesedit
This document rudimentally documents the breaking changes from 1.x to 2.x; Our 2.0 refactor comprises 1000+ commits and nearly six months of work, so if we missed anything feel free to give us a shout!
Dependency graph changesedit
The first thing you might notice is that the dependency graph for the client has changed slightly. It has also been renamed from IElasticsearchClient to ILowLevelElasticClient, to align better with the high level (NEST) client and better differentiate itself.
`IElasticLowLevelClient` ├─`ITransport` ├──`IConnectionConfiguration` ├───`IConnectionPool` ├───`IConnection` └───`Func<IConnectionConfiguration, IElasticsearchSerializer>`
a client can still be new'ed with no arguments
var lowLevelClient = new ElasticLowLevelClient();
Wich will default to a SingleNodeConnectionPool talking to http://localhost:9200
The next most common overload of the constructor is the one taking ConnectionConfiguration
var lowLevelClient = new ElasticLowLevelClient(connectionSettings);
There are many overloads to the constructor of ConnectionConfiguration that allow you to inject a custom connection or serializer factory if needed.
What they all have in common is that you have to specify an IConnectionPool implementation e.g
var pool = new StaticConnectionPool(nodes); var settings = new ConnectionConfiguration(pool); var client = new ElasticLowLevelClient(settings);
Another big change in Elasticsearch.NET 2.0 is that internally we deal with Node`s and not `Uri`s. However `nodes in the above example can be either
an IEnumerable<Uri> or IEnumerable<Node>.
For the super advanced usecases a custom ITransport can be injected.
var pool = new StaticConnectionPool(nodes); var settings = new ConnectionConfiguration(pool); var transport = new Transport(pool); var client = new ElasticLowLevelClient(pool);
This is what we call internally if you use the previous ElasticLowLevelClient constructor.
Our implementation of ITransport can be injected with a custom IRequestPipelineFactory, IDateTimeProvider and IMemoryStreamFactory.
Transport is in control of managing our request pipelining, asking connection pools for other nodes to fall over to and marking nodes dead or alive.
Each individual moving part is further explained in the index.html[documentation].
ConnectionSettings Changesedit
This lists the methods that have been renamed or removed on ConnectionConfiguration
class ConnectionConfiguration`1 - method: EnableCompressedResponses + method: EnableHttpCompression - method: EnableMetrics - method: EnableTrace - method: ExposeRawResponse + method: DisableDirectStreaming - method: HttpPipeliningEnabled + method: EnableHttpPipelining - method: SetBasicAuthentication + method: BasicAuthentication - method: SetBasicAuthorization + method: BasicAuthentication - method: SetConnectionStatusHandler + method: OnRequestCompleted - method: SetConnectTimeout - method: SetDeadTimeout + method: DeadTimeout - method: SetGlobalQueryStringParameters + method: GlobalQueryStringParameters - method: SetMaxDeadTimeout + method: MaxDeadTimeout - method: SetMaximumAsyncConnections - method: SetMaxRetryTimeout + method: MaxRetryTimeout - method: SetPingTimeout + method: PingTimeout - method: SetProxy + method: Proxy - method: SetTimeout + method: RequestTimeout - method: ThrowOnElasticsearchServerExceptions + method: ThrowExceptions - method: UsePrettyRequests + method: PrettyJson - method: UsePrettyResponses + method: PrettyJson
The same goes for the values they are settings:
interface IConnectionConfigurationValues - prop: BasicAuthorizationCredentials + prop: BasicAuthenticationCredentials - prop: ConnectionStatusHandler + prop: OnRequestCompleted - prop: ConnectTimeout - prop: EnableCompressedResponses + prop: EnableHttpCompression - prop: KeepRawResponse + prop: DisableDirectStreaming - prop: MaximumAsyncConnections - prop: MetricsEnabled - prop: ThrowOnElasticsearchServerExceptions + prop: ThrowExceptions - prop: Timeout + prop: RequestTimeout - prop: TraceEnabled - prop: TraceWriter - prop: UsesPrettyRequests + prop: PrettyJson - prop: UsesPrettyResponses + prop: PrettyJson
IConnectionPooledit
The interface for IConnectionPool has been greatly simplified, its no longer in charge of mark nodes alive or dead
interface IConnectionPool - prop: AcceptsUpdates + prop: SupportsReseeding - method: GetNext - method: MarkAlive - method: MarkDead - method: UpdateNodeList + method: Reseed
IConnectionedit
The connection interface has been stripped to the bare minimum it now only has a Request and RequestAsync method
interface IConnection - prop: AddressScheme - method: Delete - method: DeleteSync - method: Get - method: GetSync - method: Head - method: HeadSync - method: Post - method: PostSync - method: Put - method: PutSync + method: Request + method: RequestAsync
The methods take a RequestData a new state object that holds all the information to build the request.
Renamed Typesedit
This lists the types that have been renamed
- class AliasRequestParameters + class BulkAliasRequestParameters - class BasicAuthorizationCredentials + class BasicAuthenticationCredentials - class ClusterSettingsRequestParameters + class ClusterPutSettingsRequestParameters - class DeleteTemplateRequestParameters + class DeleteSearchTemplateRequestParameters - class DynamicDictionary + class DynamicResponse - class GetTemplateRequestParameters + class GetSearchTemplateRequestParameters - interface IElasticsearchResponse + interface IApiCallDetails - interface IMemoryStreamProvider + interface IMemoryStreamFactory - class IndicesExistsAliasRequestParameters + class AliasExistsRequestParameters - class IndicesExistsTemplateRequestParameters + class IndexTemplateExistsRequestParameters - class IndicesExistsTypeRequestParameters + class TypeExistsRequestParameters - class IndicesPutAliasRequestParameters + class PutAliasRequestParameters - class IndicesRecoveryRequestParameters + class RecoveryStatusRequestParameters - class InfoRequestParameters + class RootNodeInfoRequestParameters - interface IResponseWithRequestInformation + interface IBodyWithApiCallDetails - class MemoryStreamProvider + class MemoryStreamFactory - class MpercolateRequestParameters + class MultiPercolateRequestParameters - class PutTemplateRequestParameters + class PutIndexTemplateRequestParameters - class TemplateExistsRequestParameters + class IndexTemplateExistsRequestParameters
