The NuoDB Node.js driver comes with a built-in connection pool.Unlike a single connection, where an individual connection is established for each database interaction, a connection pool allows the application to reuse and share database connections rather than opening a new connection for each database operation.This approach of connection pools reduces the overhead associated with repeatedly establishing and closing connections, resulting in improved performance, responsiveness, and scalability of the application in high concurrency scenarios.To connect to the NuoDB database using a connection pool:Configure the connection poolPlease review the shape of the pool configuration to customize for specific needs.{ minAvailable: number, connectionConfig: ConnectionConfig, maxAge: number, checkTime: number, maxLimit: number, connectionRetryLimit: number, id: number, skipCheckLivelinessOnRelease: boolean, livelinessCheck: "query"|string};ParameterDescriptionconnectionConfigThe configuration that will be used to create the connection in the poolThis parameter is required.minAvailableMinimum number of connections that the pool will maintainThe default value is 10.maxAgeTime (in millisecond) from connection creation until it will age outThe default value is 300000.checkTimeThe frequency at which the pool runs an internal liveliness check on free connections.The default value is 120000.Use 0 to disable liveliness check.maxLimitThe maximum number of live connections the pool can maintain.The default value is 200.Use 0 to disable limit.connectionRetryLimitThe maximum number of times a pool will attempt to create a connection.The default value is 5.idAssigns an id for the pool.The default value is new Date().getTime() .skipCheckLivelinessOnReleaseTurns off liveliness checks on connections when they are released back to the pool.The default value is false, meaning a liveliness check will be performed when a connection is returned to the pool.livelinessCheckindicates the type of liveliness check to be performed.The default value is query, which means a query is used to test the connection.If set to any other than query, it will check if the NuoDB API isConnected returns true and a connection related exception is not trapped previously.Define a configuration objectTo connect to a NuoDB database provide a configuration object which includes the Connection Properties. Provide string values for each of the connection properties.With the configuration object defined, a connection to the desired NuoDB database can now be made.Initialize a connection poolUse the init() method to initialize a connection pool after the pool is created.This will populate the pool.The pool is now available for use.Once the pool has been successfully initialized it is ready for use.There are now free connections that can be requested for use.const poolConfig = { minAvailable: 10, connectionConfig, maxAge: 2000, checkTime: 10000, maxLimit: 12, connectionRetryLimit: 5,};async function() { const pool = new Pool(poolConfig); await pool.init()}Request connections from the connection poolRequest connections using requestConnection().You can request multiple connections.Each connection can then be used as a single connection.To see pool connections use pool.all_connections() and pool.free_connections().const conn1 = await Pool.requestConnection();Release connections back to the poolOnce the user has finished using a connection, it must be returned to the pool.This allows the connection to be reused for subsequent requests.Release one single connection at a time.Manage each single connection’s lifecycle properly before requesting its release.Connections that have failed in any way should be returned to the pool where.

Menu When using Kubernetes to deploy NuoDB, the following types of deployment are supported:Cluster-scoped deploymentsNamespace-scoped deploymentsNuoDB recommends using namespace-scoped deployments. In a namespace-scoped deployment, each new project for a NuoDB database contains its own NuoDB Admin “domain”. For information on Kubernetes deployment options, see concepts documented here.In a cluster-scoped deployment, a single central project contains the NuoDB admin “domain”. In a cluster-scoped deployment, the “domain name” is the name of this single cluster-wide project - and is typically called “nuodb”.In deployments of NuoDB managed using Kubernetes, NuoDB supports multiple NuoDB domains running in one Kubernetes cluster. In these deployments, NuoDB also supports multiple projects accessing databases from one or more NuoDB domains. In a cluster deployment, a dedicated project is set up where the NuoDB database and monitoring pods (for example, Admin and Transaction Engine pods) are located. An administration domain may be shared with other application projects where Transaction Engines (TEs) can optionally be deployed.The placement oof the NuoDB TE pods can either be in an application or in the NuoDB project; this is a logical placement not a physical one. To optimize application runtime performance, the application pod and its preferred TE should be as closely co-located as possible, thereby reducing client-side connection latency. For example, the application and TE should be in the same pod or located on the same server node.NuoDB provides flexible load balancer features to control this, and allows you to decide on how close or distant clients are located to/from TEs.

The NuoDB Collector must be set up on all hosts that will run NuoDB database processes.Once all components have been set up, NuoDB performance can be visualized by navigating to the NuoDB Insights - NuoDB Ops System Overview dashboard at where is the host that the Grafana server was started on. The default password in Grafana is admin:admin.Insights 2.0Insights 2.x introduces a breaking change. In this update, a crucial shift is the migration from InfluxDB version 1.8 to 2.7. For those transitioning from the prior Insights 1.x iteration to 2.x, it's important to be aware that access to historical InfluxDB data from the previous version will not be retained due to the migration.Migration stepsRun the following command for migrating from Insights 1.2 to 2.0.">helm upgrade Status of the ProjectThis project is still under active development, so you might run into issues.

The moment, databases such MemSQL and VoltDB are suited to some tasks but not others (by the companies' own admission). In some respects, they're limited by amount of memory your systems have (though data can spill onto disks). And according to Andy Gross, the principal architect at Basho, an outfit that offers a NoSQL database called Riak, the NoSQL crowd is slowly improving their software so that they too can provide the sort of consistency you get from VoltDB and MemSQL.The point, Gross says, is that the entire database world is evolving. So many databases -- whether they're tagged NoSQL or NewSQL -- are inching towards a new reality where we can store data across an enormous number of machines but still change and analyze it as if it was stored on a single system.Google has already reached this nirvana with a creation it calls Spanner. This mind-boggling software platform spans the globe -- literally -- but thanks to some ingenuous engineering involving GPS devices and atomic clocks, it can treat that world of data as if it's in one place.Barry Morris, the CEO and founder of NuoDB, says that his company has already brought Spanner-like technology to the masses. "Part of the magic of NuoDB," he says, "is that we can do it without atomic clocks." Others, such as Stonebraker, are skeptical, saying that unlike Spanner, NuoDB is still burdened by a lag time that would preclude rapid-fire database transactions. But at the very least, it's a step in the Google direction. And many others are moving the same way.. NuoDB Docs NuoDB. Menu NuoDB NuoDB Docs Introduction to NuoDB.
