I researched for spring boot, PostgreSQL and pgbouncer example and cannot find anywhere.
Do you know can we integrate pgbouncer with spring javax.sql.DataSource?
Can you share with me any page that can I take reference. When I look to Pgbouncer page cannot find example?

I have a database in PostgreSQL. Now we need to import whole database into DynamoDB. Data Migration service need to be used for this purpose or any other service can be used. Please explain in detail.
What is the strategy to be followed? I have studied many blogs but I couldn't get any proper way to migrate the whole database from PostgreSQL to DynamoDB. Only through DMS Service is it possible to migrate or any other service can be used to migrate or any script should be run to migrate the PostgreSQL to to DynamoDB.
The AWS Database Migration Service offers everything you would need to migrate data from any relational DB into AWS - whether the target is DynamoDB (NoSQL offering from AWS) or any of the DB flavors from AWS RDS service.
You can find multiple migration playbooks and step-by-step guides on the Resources page of this AWS service
I created a spring boot application (simple with database connection) and I would like to put it on a openshift. It's not a problem for me to generate docker image and put it into openshift, but I also want a mongodb database instance on openshift. I already created it on a openshift but know I have no idea how to connect to it from the spring boot application. I recently heard that I need to type a pod name as a connection string. Is that correct? How exactly should I connect to mongodb pod from the spring boot pod. Should I create some route between those two? I am new with playing around docker and openshift, so please try to give me as much info as you can.
Are you using your own OS3 vm?
I'm no expert on the matter, but on OS3 web console, once you create a database from templates already provided by OpenShift, OS3 shows a connection string at the end of the process.
I'm pretty sure OS3 creates a service for your db, the link looks like this:
mysql://servicename:3306/database
Can anyone please advise, what is the address if I am trying connect to an ElasticSearch node that is in-memory(just using the default config) while using Spring boot ? I am looking at something like localhost:port.
Thanks!
Ok, so it is localhost:9200, same as if running it externally.
My Mongo database is hosted at MongoLab. I'd like to use ElasticSearch as a full text search engine on top of my DB.
As I understand MongoDB needs to run as a replica-set, but I don't have any control on how the database run. I'm currently using the 500mb free plan.
On the top of that, I'm using the scala playframework.
Was anyone successful with those technologies and services?
Update:
Finally I'm not using MongoDB anymore, and went straight for a ElasticSearch solution.
I found this nice cloud host providing a 500MB free plan http://facetflow.com/
It was very useful for my development.
I didn't find any satisfying Scala library for ES, therefore I'm using Dispatch and make direct http requests to the ES instance.
I hope that someone will find this useful.
Just a quick note ... MongoHQ has oplog support with their MongoDB Elastic Deployments ... those could help you with using Elastic Search and River.

I haven't looked into this too deeply, but you might want to check out Searchly http://www.searchly.com/features/ . The features mention
Built-in crawler for crawling web pages and databases. (Currently MongoDB)
If you try this out, please let me know how it goes. I will do the same.
Update:
I haven't tried searchly, but I was able to start a MongoDB instance in replica mode on OpenShift.
I have also an Elastic Search server running on the same OpenShift "gear".
Now I need time to try connecting those two together, and then the fun will start :-)
I am trying to figure out how to build a scalable database system. I settled on using postgresql and am trying to figure out how to implement load balancing. I looked into HAProxy, which I really liked. I noticed that there were multiple different configurations of postgresql http://www.postgresql.org/docs/8.3/static/high-availability.html. Which one would be the best to link with HAProxy?
I have used HAProxy for MySQL. But that was because there were no options tailor-made for MySQL. And HAProxy does a great job. For PostgreSQL, there are quite a few tailor-made options. May be you could have a look at pgpool?
Are you looking for scalability alone, or failover too? Which version of PostgreSQL are you using?
