couchbase

问题 All examples in the Tornado documents show how we can make further HTTP requests asynchronously using Tornado. http_client = httpclient.AsyncHTTPClient() http_client.fetch("http://www.google.com/", handle_request) While I want to ensure that my tornado doesn't wait for response from database (get command of couchbase) to send next. Check my other bug to understand why I want async call to couchbase. 回答1: As far as I know Couchbase driver is not an async driver so this wont work. Make the db

问题 I'm trying to build a filter view, where I can filter documents based on a column range. My map function looks something like this: function (doc, meta) { if(!doc.tombstone) { emit([doc.effectiveDateTime]); } } When I query this view from code, the result only has the keys and not the documents. I can think of the following ways to solve this, and need help deciding which one could work. setIncludeDocs : Exploring the documentation a little bit, I came accross this java code snippet where the

问题 The error: Could not load file or assembly 'Enyim.Caching, Version=1.0.0.0, Culture=neutral, PublicKeyToken=cec98615db04012e' or one of its dependencies This is on server 2008, I tried disabling the strong name validation, but the instructions are totally wrong for server, and I dont' really trust this anyhow, how will I get it to work on the prod server. Wild frustrating.. The server is up and happily running, but I can't get any memcache client to actually work.. I assume someone, somewhere

问题 We are using couchbase 3.0 and have around 67 GB free disk space, which is 35% free. But we face this warning this morning from the tab "Cluster Overview" in couchbase's admin page: Approaching full disk warning. Usage of disk "/" on node "local.node" is around 100% Even the admin page shows the correct Disk Overview: Usable Free Space (67.9 GB). But how come this warning appears? 来源： https://stackoverflow.com/questions/32982171/couchbase-approach-full-disk-warning-while-still-have-a-lot-of

问题 I wanted to know if Couchbase support consistent incremental Counters. From what I've read in this doc, it does not, it just encapsulates a read/write operation so you won't need to do it yourself. Of course this doesn't work for me because the data might change since the time you read the data from the database. 回答1: Couchbase absolutely does, just like memcached and Membase Server, it supports the incr/decr operations atomically within a cluster. cb.set("mykey", 1) x = cb.incr("mykey") puts

问题 Is it possible to use Couchbase's Atomic Counters with the Spring Connector? Currently I have a repository for a specific document type and want to have an atomic counter for every document. I know that the Java SDK offers the functionality but I was not able to find an equivalent action for Spring. 回答1: As I know Spring doesn't have support for counters but it's pretty simple to write own repository: @Repository public class CountersRepository { private static final long INITIAL_COUNTER

问题 I am developing an Dotnet core 2.x(actually using 2.1.4, latest release when I'm writing this) web api project, in order to use couchbase as my database server, I need to use the couchbase SDK. The sdk states that it supports DotNet core 2.x. After a very basic setup and I just want to test the connectivity, I keep getting this error. HttpRequestException: The handler does not support custom handling of certificates with this combination of libcurl (7.54.0) and its SSL backend ("LibreSSL/2.0

问题 For development purposes, I want to connect my local machine to couchbase installed on remote ec2. I success in making the connection, but I get timeout when I try to access the data. I've search for the problem and found here, that the problem is probably related to the fact that couchbase returned the internal IP, which cannot be used outside of AWS. However, I did not find any solution to this. Any idea? Thanks. This is my output: In [19]: c = couchbase.Couchbase().connect(host='107.20.181

问题 I am caching my serialized POJO s(4mb-8mb size objects) concurrently into Couchbase server with CouchBase client (couchbase-client-1.4.3). for(upto 20 itertarions){ new Thread().start().. //this thread cache the objects Thread.sleep(500); // the less sleep time, the more cache failures :( } I have 2 replicated servers. The client can cach small size objects, but when the object size increases, it throws exceptions. Caused by: net.spy.memcached.internal.CheckedOperationTimeoutException: Timed

问题 This is my first attempt at couchbase. My json doc looks like this: { "member_id": "12345", "devices": [ { "device_id": "1", "hashes": [ "h1", "h2", "h3", "h4" ] }, { "device_id": "2", "hashes": [ "h1", "h2", "h3", "h4", "h5", "h6", "h7" ] } ] } I want to create a view which tells me all member_ids for a given hash. Something like this: h1["12345","233","2323"] //233,2323 are other member id h2["12345"] The member_id should appear once in the set. I wrote a map function function (doc, meta) {
