MongoDB Drivers and Network Compression

1. node-tcp-metrics

   1 1 0 5.3 TypeScript

   

   As a simple demonstration, I've instrumented a Node.js-based workload (see alexbevi/node-tcp-metrics) to hook into net.createConnection(), net.Server and tls.connect() to track the number of bytes being sent/received:

2. SurveyJS

   surveyjs.io featured

   SurveyJS: Build JSON-Driven Surveys and Forms with Full Data Control. Add the SurveyJS UI components to your JS app (React/Angular/Vue3). Securely collect and analyze data without sending it to 3rd-party servers. Fully customizable, works with any backend, and ideal for data-heavy apps. Learn more.

   

3. ZLib

   A massively spiffy yet delicately unobtrusive compression library.

   

   MongoDB supports 3 possible network compressors: zlib, ZStandard (zstd) and Snappy. zlib is always supported out of the box, however some drivers may require an additional package to support additional compressors. For example, when using MongoDB's Node.js driver, the following would be required from npm to support snappy and zstd:

   There are 4 open sockets in the example as the default Atlas configuration is a 3 member replica set. The driver has opened one socket to send commands to the server, and has also created dedicated monitoring connections to each host. If the workload were to remain active and not exit immediately, another 3 RTT connections would also be opened (one to each host in the replica set) for a total of 7 sockets. \ See the Server Monitoring specification, or "How Many Connections is My Application Establishing to My MongoDB Cluster?" for more detail. {: .prompt-info }

7. chance.js

   Chance - Random generator helper for JavaScript

   

   When this is run, the workload will create a complex JSON document using Chance, write it to a MongoDB Atlas Database, then read it back before deleting it.
