I have to do an assignment with multiple databases, and I was thinking in polyglot persistence between MongoDB an Neo4j. I have seen some of the documentation for the Neo4j doc manager, and the last time it was updated was in 2016, and it has a build fail on github. I still tried to use it, but then I had this problem and could not install py2neo 2.0.7.
Is there a solution for this, or should i give up on Neo4j doc manager?
Neo4j Doc Manager is discontinued as the last commit was 5 years ago.
You can use any APOC mongoDB procedure that are available at https://neo4j.com/labs/apoc/4.3/overview/apoc.mongodb/. In any case, you will have to develop your own ETL tool, perhaps with Apache Hop or Talend.

We have migrated a space from cloud instance to server instance,in cloud instance we were using "Plantuml diagrams for confluence" but in server we are using "Confluence PlantUML Plugin" .so macro name are different in both cloud and server ,so macro name for cloud is "plantumlcloud" but for server it is "plantuml".so ,in pages after migration it is showing "plantumlcloud" not a valid macro ,kindly help to resolve.
In general, migration of confluence spaces to another application which is not running the same plugins will cause any functionality of that plugin to break.
If you migrate hosting platforms, and have the equivalent version of the plugin for your new platform, created by the same developer, in most cases you will retain functionality, however there will often be differences between versions.
These differences are found especially when downgrading, and moving from cloud to server is a very definite example of a downgrade, as cloud will always run the latest version.
In general I would reccomend against a migration from cloud to server, and when it must be done, time should be spent to ensure compatability with all plugins, and migration guides and plans should be made and followed.
As commented by #tgdavies, there seems to be an equivelent version of the plugin you were using on cloud, so hopefully that can resolve your issue.
For simplicity and cost, we are starting our project using local MySQL running on our GCE instances. We will want to switch to CloudSQL some months down the road.
Any advice on avoiding MySQL version conflicts/challenges would be much appreciated!
The majority of the documentation is for MySQL 5.7 so as an advice I recommend you use this version and review migrating to cloudsql concept this is a guide that will guide you through how to migrate safely which migration methods exist and how to prepare you MySQL database.
Another advice which I can give you is make the tutorial migrating mysql to cloud using automated workflow tutorial this guide also says that the any MySQL database running version 5.6 or 5.7 allows you to take advantage of the Cloud SQL automated migration workflow this tutorial is important to know how works and how deploy a source MySQL database on Compute Engine. The sql page will give you more tutorials if you want to learn more.
Finally I suggest to you check de sql pricing to be aware about the billing and also I suggest to you create a workspace with this you can have more transparency and more control over your billing charges by identifying and tuning up the services that are producing more log entries.
I hope all the information that I'm giving you are helpful.
I am currently working with couchbase server 1.8.1 an in a process of upgrading to 2.2 version.
We want to dump all the keys of couchbase 1.8.1 to a text file and then run on this file and copy all the data to the new couchbase 2.2.
The reason we chose to use this method instead of backup and restore is because our server do not respond well to backup and there is a risk of server failing.
Can you help me figure out how to create this dump file from couchbase bucket files?
In addition to what Dave posted, I recommend reading this blog post: http://blog.couchbase.com/Couchbase-rolling-upgrades
Also, there are some unique considerations when upgrading from 1.8.1 to 2.x, so make sure you read the documentation Dave linked to.
Note you can upgrade an existing cluster online (without having to manually copy data to a new 2.2 cluster) - see http://docs.couchbase.com/couchbase-manual-2.5/cb-install/#upgrading
We use this script: CouchbaseDump
It works and help us getting the keys from the sqlite files.
i'm using mongodb to store data.
But to search I prefer to use elasticsearch or similar. But i didn't found solution.
Because I read some problems and issues with RIVER .
What's your experience and recommendations ?
I'm using elasticsearch with mongodb. I tried Solr but I didnt have the integration. The two tools are using the lucene so has "approximately" the same query syntax.
There are some tutorial, but it didnt work for me. I believe the reason is that the github doesnt allow now to upload and download binary files. So, we can not use the ./plugin command. To overcome this problem you have to git clone the repositories and make the .jar files on your own. To do that you have to use apache maven and make mvn package to create the packages.
Add both river and Mapper Attachments to elasticsearch. And make sure that you follow the compatible versions according to the river version table.
After that everything will working file.
Recently I discovered the power of noSQL database MongoDB. After a lot of trial and error I was able to install it on my pc along with wampserver. Its running smoothly. Now the question I would like to ask is, that if I want to integrate the MongoDB service provided by Mongolab on my shared hosting plan, is there any class available that helps me connect to the database? Like a php class version of the driver for php and mongodb. As it is not possible to install the driver on my hosting, because of no root access. So is there a raw class available as an alternative to the driver dll?
If you can't install the driver, then the REST interface provided by MongoLab is your best bet - any language that can send/receive a HTTP request can use REST:
