A Docker image is a read-only template used to build containers. Images are used to store and ship applications. [22] A Docker service allows containers to be scaled across multiple Docker daemons. The result is known as a swarm, a set of cooperating daemons that communicate through the Docker API. [22] Registries: A Docker registry is a ...
Container classes are expected to implement CRUD-like methods to do the following: create an empty container (constructor); insert objects into the container; delete objects from the container; delete all the objects in the container (clear); access the objects in the container; access the number of objects in the container (count).
Third party support for database container images has grown, including MongoDB, PostgreSQL, MySQL from Oracle, and Microsoft SQL Server from Microsoft, and from independent port's of docker (software) from Windocks [2] Kubernetes, and the development of the Kubernetes Operator pattern by CoreOS, further extended the ability to orchestrate ...
The default maximum RUs that can be provisioned per database and per container are 1,000,000 RUs, but customers can get this limit increased by contacting customer support. As an example of costing, using a single region instance, a count of 1,000,000 records of 1k each in 5s requires 1,000,000 RUs At $0.008/ h , which would equal $800 .
The director database, made of a PostgreSQL instance, a Redis instance and a Blobstore for storing compiled packages and jobs; A Health Monitor that keeps track of instances (VMs or containers) status; Many BOSH agents, one on each deployed instance; A NATS message bus for connecting the Director, the Health Monitor, and all the deployed BOSH ...

Among its many features is the ability to use String or UUID based entity IDs. FROST-Client [18] is a Java client library for communicating with a SensorThings API compatible server.
DELETE requires a shared table lock; Triggers fire; DELETE can be used in the case of: database link; DELETE returns the number of records deleted; Transaction log - DELETE needs to read records, check constraints, update block, update indexes, and generate redo / undo. All of this takes time, hence it takes time much longer than with TRUNCATE
