Installation Instructions. View on GitHub. Readonly Edition This version is limited strictly to read operations, with all write and delete capabilities removed. Isolated Edition This version disables all network connections except the connection to the MongoDB instance. This article is part of our MongoDB Guide. Use the right-hand menu to navigate. Docker is a tool to create, deploy, and run applications using containers easily. A container is a standard unit of software that can be used to package applications and all the dependencies to a single package.
These containers can be run on any server platform regardless of the underlying configuration or hardware structure. Docker can be used to run MongoDB instances. A containerized MongoDB instance behaves exactly like a non-containerized MongoDB instance without having to worry about the underlying configuration. We can get the Docker installation packages from the official Docker repository.
Here are the installation steps:. We can use the command line interface CLI to create and manage Docker containers. However, the CLI can be tedious when dealing with multiple containers and configurations. Docker Compose allows users to take multiple containers and integrate them into a single application.
Docker Compose uses the YAML format to create the compose files that can be easily executed using docker-compose up or down commands that will create or remove all the containers and configurations within a compose file, respectively. The search results show us that an official MongoDB container image called mongo exists in the docker container registry. This will enable local access to the database.
We use the -pv operator to create those parent folders. The following docker-compose. A schema defines document properties through an object where the key name corresponds to the property name in the collection. Here we define a property called email with a schema type String which maps to an internal validator that will be triggered when the model is saved to the database.
It will fail if the data type of the value is not a string type. We need to call the model constructor on the Mongoose instance and pass it the name of the collection and a reference to the schema definition. A schema definition should be simple, but its complexity is usually based on application requirements.
Schemas can be reused and they can contain several child-schemas too. In the example above, the value of the email property is a simple value type. However, it can also be an object type with additional properties on it.
We can create an instance of the model we defined above and populate it using the following syntax:. We can also add a validation function that will ensure that the value is a valid email address. We will reference and use the validator library installed earlier. Mongoose has a flexible API and provides many ways to accomplish a task.
We will not focus on the variations because that is out of scope for this article, but remember that most of the operations can be done in more than one way either syntactically or via the application architecture. If you try to repeat the save operation above, you will get an error because we have specified that the email field should be unique. The model class exposes several static and instance methods to perform operations on the database.
What's a pattern field? Regular expression What is a choice? Parquet schema Apache Parquet is a binary file format that stores data in a columnar fashion for compressed, efficient columnar data representation in the Hadoop ecosystem.
Parquet Schema The root of the schema is a group of fields called a message. DATE is used to for a logical date type, without a time of day. It must annotate an int32 data types that stores the number of days from the Unix epoch, 1 January TIME is used for a logical time type without a date with millisecond or microsecond precision.
It must annotate an int32 that stores the number of milliseconds after midnight.
