Hi ,
I have problem about this issue ; could not serialize access due to read/write dependencies among transactions A message app like whatsapp i decided to use isolation level serializable if i use other transaction levels many conversations started with same number (think about whatsapp web sidebar multipling with same number every message). I also add an index to my query and my query's execution plan don't use seq scan . How can i solve this issue ? Can i solve this on db orr on app ?
