Couchbase vs SAP HANA

• Couchbase performance is exceptional both for in-memory and persisted transactions.
• Handling of node failures and cluster rebalancing (high availability).
• Enterprise support from Couchbase themselves
• Good documentation
• Streaming of bucket (database) level mutations via their Database Change Protocol (DCP).
• Replication of datasets between native clients and Couchbase buckets
• Handling of simultaneous writes to the same record with performance penalties

• If required, SAP S/4HANA may be installed and configured on the cloud.
• Because of the simplification of functionality, IT personnel may be able to devote more of their time and resources to delivering services rather than doing maintenance tasks.
• Assist businesses in making better decisions about their operations by providing better information.
• SAP HANA is a superb web solution with advanced remote data synchronization capabilities that is very quick and easy to use.

• The N1QL engine performs poorly compared to SQL engines due to the number of interactions needed, so if your use case involves the need for a lot of SQL-like query activity as opposed to the direct fetch of data in the form of a key/value map you may want to consider a RDBMS that has support for json data types so that you can more easily mix the use of relational and non-relational approaches to data access.
• You have to be careful when using multiple capabilities (e.g. transactions with Sync Gateway) as you will typically run into problems where one technology may not operate correctly in combination with another.
• There are quality problems with some newly released features, so be careful with being an early adopter unless you really need the capability. We somewhat desperately adopted the use of transactions, but went through multiple bughunt cycles with Couchbase working the kinks out.

• Great performance.
• Leading Couchbase Lite capabilities for mobile use.
• Developers' learning curve with replica reads and multi cluster can be long. Needs guidance and nurturing.
• Cluster maintenance during OS patching, etc. has multiple ways to approach. Operational teams may need some guidance.

• Wide variety of data types can be maintained easily, so flexibility is in our hands.
• The decision we made by analyzing the generated report really had a great positive impact.
• Considering the scalability SAP HANA offers, it is the best investment.
