Database Application level sharding is the process of splitting a table into multiple database instances in order to distribute the load. However, Sharding a database is an expensive operation (maintainability and overhead) and I suggest you do that only when you absolutely need to. That means when your single instance database can no longer serve queries with minimum latency. So I suggest you monitor that and only shard if necessary.. I rather do replication make master / backup and make requests read from replica than Sharding just because it is easier.. good question... nice idea for a video Time codes 0:00 Intro 5:00 Partition horizontally 7:45 Replication (Master/backup) Scale reads 11:00 Scale writes by region 12:30 Sharding 16:40 Sharding in YouTube 🏭 Software Architecture Videos https://www.youtube.com/playlist?list=PLQnljOFTspQXNP6mQchJVP3S-3oKGEuw9 💾 Database Engineering Videos https://www.youtube.com/playlist?list=PLQnljOFTspQXjD0HOzN7P2tgzu7scWpl2 🛰 Network Engineering Videos https://www.youtube.com/playlist?list=PLQnljOFTspQUBSgBXilKhRMJ1ACqr7pTr 🏰 Load Balancing and Proxies Videos https://www.youtube.com/playlist?list=PLQnljOFTspQVMeBmWI2AhxULWEeo7AaMC 🐘 Postgres Videos https://www.youtube.com/playlist?list=PLQnljOFTspQWGrOqslniFlRcwxyY94cjj 🚢Docker https://www.youtube.com/playlist?list=PLQnljOFTspQWsD-rakNw1C20c1JI8UR1r 🧮 Programming Pattern Videos https://www.youtube.com/playlist?list=PLQnljOFTspQV1emqxKbcP5esAf4zpqWpe 🛡 Web Security Videos https://www.youtube.com/playlist?list=PLQnljOFTspQU3YDMRSMvzflh_qXoz9zfv 🦠 HTTP Videos https://www.youtube.com/playlist?list=PLQnljOFTspQU6zO0drAYHFtkkyfNJw1IO 🐍 Python Videos https://www.youtube.com/playlist?list=PLQnljOFTspQU_M83ARz8mDdr4LThzkBKX 🔆 Javascript Videos https://www.youtube.com/playlist?list=PLQnljOFTspQWab0g3W6ZaDM6_Buh20EWM 👾Discord Server https://discord.gg/CsFbFce Support me on PayPal https://bit.ly/33ENps4 Become a Patreon https://www.patreon.com/join/hnasr?
