MongoDB from setup to daily operations: installation, replica sets, sharding, backups, security and performance.
mongorestore –oplogReplay gives you point-in-time recovery for a whole instance, replayed from the captured oplog of a single backup. It has no equivalent for a single database or a single collection. Say you need “restore just this one collection to 4:35pm” instead of the whole instance. The supported tooling has nothing to offer for in-place namespace point-in-time recovery (PITR). The…

When the cloud admin is the threat: how SQL Server and MongoDB let you query encrypted data, and what each approach costs.
Since version 7.0.11, MongoDB natively supports OpenID Connect (OIDC) authentication. This move was part of MongoDB’s cloud strategy, since cloud environments use OIDC a lot for authentication and authorization. In version 8.0, MongoDB deprecated LDAP authentication and authorization, making it clear that OIDC is the future for MongoDB authentication. In this blog, I will present how to set up OIDC…

When securing a MongoDB deployment, protecting sensitive data is essential. MongoDB supports encryption throughout the lifecycle of the data, with three primary types of data encryption : Among these, encryption in transit is fundamental : it protects data as it moves between your application and the database. In MongoDB, this is achieved through TLS (Transport Layer Security), which ensures that…
If you’ve ever had to deal with MongoDB after years (or even decades) of working with SQL, you’ve probably realized that querying JSON documents can sometimes be painful, to say the least. In response to this, Oracle (and others) use a not-so-native adaptation of SQL to query JSON documents. And if you’ve ever had to deal with these SQL-based JSON…
Contrary to other DBMS, MongoDB self-managed deployments generate logs in a JSON format, which can be quite intimidating at first. But instead of hoping to never have to look at the logs, you can use some tools and tips to navigate them more easily and not waste time finding the information you’re looking for. Log format overview Inside /var/log/mongodb/mongod.log (or…

OPS Manager also allows you to deploy a complete MongoDB cluster in multiple nodes and several topologies. As you know, at dbi services, the MongoDB installation is based on our best…
