Adabas vs. Couchbase Server

It's well suited for applications running on z/OS I wouldn't consider it for applications on other operating systems

Best suited when edge devices have interrupted internet connection. And Couchbase provides reliable data transfer. If used for attachment Couchbase has a very poor offering. A hard limit of 20 MB is not okay. They have the best conflict resolution but not so great query language on Couchbase lite.

• It's efficient
• uses relativly few resources

Incentivized

• Easy to store unstructured data and has great performance
• Managing security is super easy which can be managed across different levels
• UI is pretty simple to use and manage the cluster
• Backup of the data is very easy and the restoration/recovery is fairly easy as well with the in-built tools.
• Easy integration with elasticsearch for replication
• It is fairly easy to scale up or scale down the cluster

Incentivized

• Using newer features of z/OS
• pricing

• Cluster sizing during the design phase can be improved, especially if the client lacks prior experience. Vendor consultants are very meticulous in order to provide best of class performance and response time, although some more real-world pragmatic approach is often needed.
• Couchbase Lite 2 went thru a major revamp, which broke the compatibility of the applications with some features removed and other changed. That needed development teams working to refactor the applications.

Converting to another DBMS is a huge project.

I rarely actually use Couchbase Server, I just stay up-to-date with the features that it provides. However, when the need arises for a NoSQL datastore, then I will strongly consider it as an option

Couchbase has been quite a usable for our implementation. We had similar experience with our previous "trial" implementation, however it was short lived.

Couchbase has so far exceeded expectation. Our implementation team is more confident than ever before.

When we are Live for more than 6 months, I'm hoping to enhance this rating.

One of Couchbase’s greatest assets is its performance with large datasets. Properly set up with well-sized clusters, it is also highly reliable and scalable. User management could be better though, and security often feels like an afterthought. Couchbase has improved tremendously since we started using it, so I am sure that these issues will be ironed out.

I haven't had many opportunities to request support, I will look forward to better the rating. We have technical development and integration team who reach out directly to TAM at Couchbase.

Adabas uses resources better than DB2, but it doesn't use newer features of the hardware or operating system.

Couchbase could outperform it's competition considerably for database reads and writes. Full text searches were still faster in Elasticsearch but this is more of a feature than a base platform requirement for us.

So far, the way that we mange and upgrade our clusters has be very smooth. It works like a dream when we use it in concert with AWS and their EC2 machines. Having access to powerful instances along side the Couchbase interface is amazing and allows us to do rebalances or maintenance without a worry

• Every time we want to upgrade our computer, the pricing for adabas is a big concern

• There have been several areas of our application [that] really needed an ACID compliant database (e.g. strong transactional guarantees) that we thought we could work around while using Couchbase. [In my opinion] that turned out to be a poor bet. You need to be certain that the specific characteristics of a NoSQL database fit your problem.
• Couchbase does eliminate the need for schema upgrades completely. I.e no downtime or conversion windows as you migrate your data model, adding attributes, etc. This helped with the deployment timeframe associated with DB changes.
• The database is (apparently) a bit more of a space/memory consumer than originally anticipated. During deployments, we received constant pressure from Couchbase consulting teams to eliminate/reduce the number of indexes, and this was because any mutations to docs in a bucket must check for impact against all indexes. More recent years have started to address this with their "collections" features, which helps isolate indexes to specific sub-groupings of documents.
