Develop the Websocketd server (written in C/C++, well-commented source code along with seastar) running on scyllaDB DB server. for Websocketd clients to access to scyllaDB that will have the real-time data streaming/historical data download based on our own custom REST API requests based on well-known/tested API. See here: [login to view URL] [login to view URL] [login to view URL] ScyllaDB database server running on dedicated high-end server with RAID10/1 drives (already installed) Read [login to view URL] and [login to view URL] for details. Seastar examples: [login to view URL] Notes: 1) seastar can be used due to well-documentation there for faster and better quality development results. [login to view URL] and [login to view URL] for details. ( Seastar examples: [login to view URL] ) 2) scyllaDB is already installed on dedicated DB server (192GB RAM, dual XEON CPUs – 32 cores, RAID1 & RAID10 SSD drives), ready for use. 3) Dedicated DB server uses CentOS8 with latest installed libraries and development tools. 4) No docker, framework or virtual services can be used on dedicated server. Code and files must be 100% native, running on DB dedicated server. (SeaStar is considered as framework, which is acceptable). 5) My company owns all dedicated servers. Will provide the PDF documentation for the right developer who is interested in this project. NOTE: Interview via chat will be helpful for me to find the right developer. The developer will need to complete the PHP and C/C++ coding skill test from me - to allow me to assess the coding skills. If you are good, please bid this project and contact me via chat. Keywords: C/C++, Linux, Database, seastar, websockets, scylladb, php.
