key takeaway : redis solves following issues : #1 minimize the cost by not just adding more computing power, databases, Redis can achieve same workload using much less servers # 2 support adding new features and stay flexible by using flexible data structures #3 how to keep it fast by not merely adding physical mysql databases but by using redis Redis features: #1 fast, #2 flexible data structures it can save #3 extensibility ( f.x you can add search module to turn redis into mini google)
At about 41:00 - CRDT are a concept introduced by Barbara Liskov and Andrew Myers in "A Decentralized Model for Information Flow Control" published in 1997, not exactly a "very new concept in computer science," to me. Still totally awesome news that Redis supports it intentionally.
20:17 Does the Redis MULTI and EXEC acts as a transaction? If 2nd operation fails, will the 1st operation rollback? As per my exploration, this doesn't ensure rollback.
Hi redis labs.. i have a question i hope you can help me, i am developing a aplication with lambda function.. which uploads to aws database with a minimum of 10000 data I wanted to make streaming upload so that the users can track the progress on how many files are already succesfully insert to datatabase .the users on the client side can see how much percentage is already done inserted from a 10000 data to aws database. The client is just listening to socket port with redis. Thanks

Redis Transactions don't work like that, so no the first op won't be rolled back. Details here: redis.io/docs/manual/transactions/
For a unique list of emails, SETNX should be used. SET will overwrite the existing value before version 2.6.12.
first time seeing access is represented going from right to left
To implement “Write through” I have to write on SQL and Redis at the same time?

"INCR" does not set value to 0 if it does not exist, it sets the value to 1.
can you share me your slide , please...
always plan of stealing in ur mind
Superb.
