GitHub Outage - How databases are managed in production

[@manish-mk]

Love to see your consistency brother ! I always wait for your videos as well as newsletters :)

[@akashanand3783]

Thanks for this informational video

[@AsliEngineering]

Thank you so much Akash 🙌

Really a super cool video and now I know "A lot to know a lot to discuss".

[@sritejaparimi6605]

Hi Arpit, There will be multiple instances of proxySQL right? And if there are multiple the max connection pool each instance can have is MAX_DB_CONNECTIONS/No. of instances? I am thinking if we want to add/remove instances the connection pool for each instance also changes and how are we going to make sure it gets updated for each instance?

Can you please provide the handwritten notes for all of your videos posted on youtube starting from System Design? It will be of great help for all of us.

[@dhruvilshah9098]

Thank you, learned many things new in this video.

[@anupampandey3758]

if they reverted, did it not cause other issues which needed them to upgrade proxySQL version

Ok so now I got it how database are managed in production. But wondering how do you manage your time by being a data engineer manager in Unacademy and creating such quality contents. :D

[@AsliEngineering]

I wake up at 6 every day 😀 to either prepare for the video or shoot the video ⚡

[@adianimesh]

@@AsliEngineering kudos !

[@SudhanshuShekhar6151]

Awesome learning, Thanks again. I am afraid, being such a big company they must be having Release notes for any deployment, at least it helps the team to narrow down the issue during the crisis.

Is single node recovery done manually? Does it necessarily require developer intervention?

[@suryakantasahoo9935]

Great content !

[@tharun8164]

Wouldn't there be data loss due to automatic failover? since typically the replication will be async.

[@pushprajsingh595]

Is there an alternative like proxysql for mongdb.

[@mayuragrawal4410]

Orchestrator while promoting a replica to be the master, shouldnt it also spawn a new replica to have same number of nodes configured initially???

[@manmohanmundhraa3087]

May be restarting replica server then making it master will work. Other reason may be because replica is optimized for read not for write....

[@tharun8164]

Could you add related resources, text books to your videos for further deep dive. Thanks.

[@subee128]

Thanks

[@shwethanayak2459]

flapping like a domino effect

[@tushargupta764]

Another leaning: if your reverts fail as well, keep reverting until you have no code left :p

[@AsliEngineering]

No code, no bug, no outage 🔥🔥
