Database scaling patterns Mariusz Gil the we a way
ABOUT ME
EXPERIENCE from 1 to 100+ DB servers
EXPERIENCE from 1 to 100+ DB servers
What i it a ABOUT ?
DATABASE IS MAIN PROBLEM IN 99% OF WEB APPS
TYPICAL ISSUES? NORMALIZED TO xNF INEFFICIENT SCHEMA, BAD INDEXES AND
QUERIES, UNUSED SLOW-LOG
shared setup
!" # $ %% & ' !( !" # !" # shared server
cache all the things, wisely...
!" # $ %% & ' !( !" # !" # shared server
separated servers
!" # $ %% & ' !( !" # !" # DB server
scale up

denormalization
DB server
!" # $ %% & ' !( !" # !" # !" # $ %% & ' !( !" # !" # DB server
DB server
!" # $ %% & ' !( !" # !" # DB server !" # $ %% & ' !( !" # ) !" # )
DB server DB server
!" # $ %% & ' !( !" # ) !" # ) # $ %% & ' !( !" # !" # ID SENDER_ID RECEIVER_ID ... 1 10 1 2 20 2 3 10 1 4 20 3 5 10 1 6 20 4 7 10 1 USER_ID MESSAGE_ID 1 1 1 3 1 5 1 7 2 2 3 4 4 6 USER_ID MESSAGE_ID 10 1 10 3 10 5 10 7 20 2 20 4 20 6
replication
MASTER-SLAVE scale reads, but not writes
DB master
!" # $ %% & ' !( !" # ) !" # ) DB slave !" # $ %% & ' !( !" # ) !" # ) DB slave !" # $ %% & ' !( !" # ) !" # ) ... INSERT... UPDATE... DELETE... SELECT... SELECT...
MASTER-MASTER just for HA, not for scaling
DB master
!" # $ %% & ' !( !" # ) !" # ) DB master !" # $ %% & ' !( !" # ) !" # ) INSERT... UPDATE... DELETE... SELECT...
sharding
DB shard $ %% &
' !( !" # ) !" # ) DB shard !" # $ %% & ' !( !" # ) !" # ) DB shard !" # $ %% & ' !( !" # ) !" # ) INSERT... UPDATE... DELETE... SELECT... INSERT... UPDATE... DELETE... SELECT... INSERT... UPDATE... DELETE... SELECT...
Sharding i HARD !
Resharding i HARDER !
JOINS FORGET ABOUT IT data could be splitted into many
shards
ALTERS THINK TWICE ABOUT IT altering many shards could be
a nice challenge
fault tolerant multi-master sharding
SCALE WHEN NECESSARY NOT FOR FUN
Alternative TOOLS ?
None
None

Thanks! Any questions? @mariuszgil
