Replicate a single table

由 萝らか妹 提交于 2019-12-04 15:54:18
问题 Is it possible to replicate a single table? 回答1: Yes this is possible. Have a look at the slave options of the MySQL manual. This still requires to create a complete binlog of the whole database though. 回答2: To sync specific tables again to one or more slaves rather use pt-table-checksum and then pt-table-sync That should automatically identify the out-of-sync tables and only sync those. 回答3: I know this is an old question but this is for anyone who comes here looking for an answer: CREATE

CouchDB filtered replication - remove a document

由 老子叫甜甜 提交于 2019-12-04 13:45:39
问题 I am trying to setup filtered replication between a master and user database. Documents in the master contain a list of user groups that have permission to the document. { _id: 'one', groups: ['a', 'b'] } { _id: 'two', groups: ['c', 'd'] } I created a filtered view of the database that only allows user with the group to get a copy of the replicated document (hard coding the group of 'a' in this example) { filters = { users = function(doc, req){ return doc.groups.indexOf(req.query.group) != -1

How do I install and setup the RavenDb index replication

由 前提是你 提交于 2019-12-04 13:08:44
问题 rI've looked at the questions and indeed the RavenDb docs. There's a little at RavenDb Index Replication Docs but there doesn't seem any guidance on how/when/where to create the IndexReplicationDestination Our use case is very simple (it's a spike). We currently create new objects (Cows) and store them in Raven. We have a couple of queries created dynamically using LINQ (e.g. from c in session.Query<Cows> select c ). Now I can't see where I should define the index to replicate. Any ideas? I

问题 I have a 2 node cassandra cluster with a replication factor of 2 and AutoBootStrap=true. Everything is good during startup and both nodes see each other. Let us call these nodes A and B. Add a set of keys and columns (lets call this set K1) to cassandra through node A. Connect to node A and read back set K1. Same on Node B. Success - Good Kill Cassandra process on Node B. Add set K2 through A. Connect to node A and read set K2. Good Restart Cassandra process on Node B. Try to read all keys

Is there a useDirtyFlag option for Tomcat 6 cluster configuration?

由 百般思念 提交于 2019-12-04 11:59:08
In Tomcat 5.0.x you had the ability to set useDirtyFlag="false" to force replication of the session after every request rather than checking for set/removeAttribute calls. <Cluster className="org.apache.catalina.cluster.tcp.SimpleTcpCluster" managerClassName="org.apache.catalina.cluster.session.SimpleTcpReplicationManager" expireSessionsOnShutdown="false" **useDirtyFlag="false"** doClusterLog="true" clusterLogName="clusterLog"> ... The comments in the server.xml stated this may be used to make the following work: <% HashMap map = (HashMap)session.getAttribute("map"); map.put("key","value"); %>

Endless recovering state of secondary

由 六月ゝ 毕业季﹏ 提交于 2019-12-04 10:52:27
问题 I build a replication set with one primary, one secondary and one arbiter on MongoDB 3.0.2. The primary and arbiter are on the same host and the secondary is on another host. With the growing of write overload, the secondary can't follow the primary and step into the state of recovering. The primary can connect to the secondary as I can log to the secondary server by Mongo shell on the host of primary. I stop all the operations and watch the secondary's state with the command rs.status() and

SQL Replication Setup - Almost There

由 只愿长相守 提交于 2019-12-04 10:38:32
I'm trying to setup replication between two SQL Servers and I'm almost there but stuck on a permission error (it appears). The servers are connected via VPN. Publisher/Distributer = W2003 + SQL2005 (Domain Controller) Subscriber = W2008 + SQL2008 (Stand Along Server not on a domain) I have set it up to Pull rather than push only because that's the way I got past the logins issue. Current status is that both agents are running and the snapshot has completed but it doesn't start replicating. There error is below which seems to indicate that the Subscriber does not have permissions to the

Step by step instruction for secure replication?

Not sure if the question should rather be on ServerFault ? I have a couchDB setup on my server using Apache credentials (but I can switch that off if it is an distraction). I have local instances on various laptops. Now I want to setup secure (continuous) replication. From my understanding I could use username/password, SSL certificates or OAuth. I found bits and pieces of information: SSL Question on serverFault the WIKI entry on replication how to on replication in the wiki the gist on 1.2 replication the replication algorythm All this documents added a hunch, but also confusion (I'm just a
