Conflicts Changes feed Map/reduce queries Compacting and destroying Local documents Conflicts are an unavoidable couchdb document update conflict reality when dealing with distributed systems. And make no pouchdb conflict 409 mistake: client-server is a distributed system. CouchDB and PouchDB differ from many other couchdb update document sync solutions, because they bring the issue of conflicts front-and-center. With PouchDB, conflict resolution is entirely under your control. PouchDB exactly implements http://stackoverflow.com/questions/5806560/data-conflict-409-error CouchDB's replication algorithm, so conflict resolution works the same in both. For the purposes of this article, "CouchDB" and "PouchDB" may be used interchangeably. Two types of conflicts In CouchDB, conflicts can occur in two places: immediately, when you try to commit a new revision, https://pouchdb.com/guides/conflicts.html or later, when two peers have committed changes to the same document. Let's call these immediate conflicts and eventual conflicts. Immediate conflicts Immediate conflicts can occur with any API that takes a rev or a document with _rev as input – put(), post(), remove(), bulkDocs(), and putAttachment(). They manifest as a 409 (conflict) error: var myDoc = { _id: 'someid', _rev: '1-somerev' }; db.put(myDoc).then(function () { // success }).catch(function (err) { if (err.name === 'conflict') { // conflict! } else { // some other error
the database, store new data, and perform views and formatting of the information stored within the documents. Requests to the API can be categorised by the different areas of http://couchdb-13.readthedocs.io/en/latest/api-basics/ the CouchDB system that you are accessing, and the HTTP method used to send the request. Different methods imply different operations, for example retrieval of information from the database is typically handled by http://guide.couchdb.org/draft/conflicts.html the GET operation, while updates are handled by either a POST or PUT request. There are some differences between the information that must be supplied for the different methods. For a guide to error code the basic HTTP methods and request structure, see Request Format and Responses. For nearly all operations, the submitted data, and the returned data structure, is defined within a JavaScript Object Notation (JSON) object. Basic information on the content and data types for JSON are provided in JSON Basics. Errors when accessing the CouchDB API are reported using standard HTTP Status Codes. A guide to the generic error code 409 codes returned by CouchDB are provided in HTTP Status Codes. When accessing specific areas of the CouchDB API, specific information and examples on the HTTP methods and request, JSON structures, and error codes are provided. For a guide to the different areas of the API, see CouchDB API Overview. Request Format and Responses¶ CouchDB supports the following HTTP request methods: GET Request the specified item. As with normal HTTP requests, the format of the URL defines what is returned. With CouchDB this can include static items, database documents, and configuration and statistical information. In most cases the information is returned in the form of a JSON document. HEAD The HEAD method is used to get the HTTP header of a GET request without the body of the response. POST Upload data. Within CouchDB POST is used to set values, including uploading documents, setting document values, and starting certain administration commands. PUT Used to put a specified resource. In CouchDB PUT is used to create new objects, including databases, documents, views and design documents. DELETE Deletes the specified resource, including documents, views, and design documents. COPY A special method that can be used to copy documents
