MongoDB's cluster components and deployment are explained here, and I assume that it is prior knowledge, so I'll avoid repeating.Ĭouchbase deployment starts with the key-value data service. These services are loosely coupled - they run in different process spaces and communicate via a network, hence they can be deployed uniformly in a single node or distributed multi-dimensionally on a cluster. Each service is a layer in the traditional database. Mongos acts as the coordinator and mongod is the worker bee.Ĭouchbase can be deployed in a uniform distribution with each node managing the data and all services data, index, query, analytics, and eventing. Mongod process (service) manages data, index, and query on every shard (node) whereas Mongos does the distributed query processing and merging from intermediate results and does not manage any data or index. The config servers store the metadata and configuration for the cluster.MongoDB is uniformly distributed and Couchbase is multi-dimensionally distributed. Without explicit shard, each collection remains in a single shard. In MongoDB, you can scale by sharding the collection into multiple nodes. CB116o - Introduction to Couchbase for Oracle ExpertsĬluster deployment: As with most NoSQL databases, both MongoDB and Couchbase can scale out. ![]() CB116m - Intro to Couchbase for MSSQL Experts.If you know RDBMS like Microsoft SQL Server and Oracle, we have easy to follow courses to learn do the mapping of your database knowledge to Couchbase with these two courses: Until we publish that, you'll have to read this article. We're working on an online training course for MongoDB experts to learn Couchbase easily. As you progress in your database evaluation and evolution, you should learn about other JSON databases. While it's easy to start with MongoDB to learn NoSQL and flexible JSON schema, many customers choose Couchbase for performance, scale, and SQL. MongoDB University has trained a large number of developers to develop the MongoDB database. In the last dozen years, it has grown from its humble beginnings of a single lock per database to a modern multi-document transaction with snapshot isolation. How can I manage this? Currently both the app as well as Couchbase is running on the same notebook.Six thousand years ago, the Sumerians invented writing for transaction processing - Gray and Reuterīy any measure, MongoDB is a popular document-oriented JSON database. Is that correct or am I completely wrong here? I know there is no plugin existing for Xojo to integrate directly with Couchbase. As well as retrieve it out again via a RESTful call (GET) from Couchbase back to my app. So my laymen’s understanding is that I can push (PUT) a JSON document directly from my app (either desktop or web) to Couchbase. As one of them, I can tell you, not fun, not cheap. There might be like 5 people who’ve done that at some point. Since you’ve got a client-server thing going, you shouldn’t pay a performance penalty that negates the debuggability advantage.īut back to database plugins… With a fairly standard SQL database and nicely working C client libraries, you could easily get bogged down in the nuances of matching Xojo’s Database model to your client libraries. From a debugging standpoint, that approach will save you weeks of work. Another would be to use (or find) a server-side RESTful interface for your database, and call it through HTTPSocket from your apps. One is to use declares into the platform C library. My thinking is or not.įrom there, you might consider some other options rather than wrapping the platform C library in a plugin. It’s being briefly described in the Xojo forum like this (and again I hardly have a clue what they talk about):īefore going down the path of writing a database plugin, you might try to figure out if your favorite NoSQL database really matches that model or not. It’s a feasibility study where I want to find out if I can get Xojo (which compiles into executable code for Windows, Mac OS or Linux - can also become a web application) to push JSON documents directly to Couchbase via a RESTful interface and call it through HTTPS socket. I’m using Xojo ( ) at the moment to write a simple demo application that is parsing transactional records from the Telecommunications industry (so called Call Detail Records, CDR’s).
