couchbase

问题 I am new to Couchbase. I was in the process of checking raw performance of INSERTs with various Couchbase setups (single node, 2-node, 5-node etc.) I am using VMs on Windows Azure to do my testing since I do not have enough hardware to test it on my servers. I am using the .NET client library provided by Couchbase to write my C# based test application that does record insertion in a loop. Also, I am not using any bulk insert options (if any exist!) Here are the results of inserts thus far:

问题 I have a list of small JSON documents in the format: { "name":"Kate", "event":"read" }, { "name":"Jon", "event":"delete" },... My map function is this: function(doc, meta){ emit(doc.event, null); } As a result I get a list of all events, including duplicates. How do I reduce the resultset to distinct values only? Thank you 回答1: This is the answer from the other question, modified to suit this question. I hope this helps someone! The reduce function: function(keys, values, rereduce) { return

问题 I didn't see any way to insert documents in bulk using Couchbase Python client. Any example of how to insert documents in bulk using REST api? 回答1: I am answering here for Couchbase only, as you probably know they are 2 different project with different features.

So to do that you can use: - the standard set/add methods - the cbdocloader command line tool that allows you to inject data from the file system into Couchbase Server see :

问题 I have a document in CB which has two dates, a start date and an end date. Let's say, a product's price discount. 10% off starting from today and ends next Friday.

Then I can do a simple if(doc.FromDate < dt && doc.ToDate > dt){ emit([ ..... ]); This filters the documents how I want. But... Question Is this a good approach re view

问题 I am new to ElasticSearch and Couchbase. I am building a sample Java application to learn more about ElasticSearch and Couchbase. Reading the ElasticSearch Java API, Filters are better used in cases where sort on score is not necessary and for caching. I still haven't figured out how to use FilterBuilders and have following questions: Can FilterBuilders be used alone to search? Or Do they always have to be used with a Query ? ( If true, can someone please list an example? ) Going through a

问题 In Couchbase Java client there are obsPollInterval & obsPollMax parameters that can be set on the client. How do I set the equivalent in .NET client? obsPollInterval & obsPollMax 回答1: Not exactly, the two clients have slightly different implementations. The closest thing would be the ObserveTimeout configuration value which defaults to 1 minute and internally the observe will happen every 500ms until either the timeout is reached or operation succeeds.
