external scheduler for delayed jobs
- PvP march
- PvE march
- Job
-
serializer for concurrent updates
- lock container/issuer with retry mechanism
- actor make concurrent calls into sequential calls
-
coodinator
- everything that may lead to race condition and concurrent updates will be decided by actor
- worker php, retry only when errno=1(locked)
- when faed restart, actor couldn't get lock any more. try restart fae, what actor happens?
- what if beanstalk conn broken?
- A encamp，然后1万人同时到，轮流打他，那么这个阶段，A啥也干不了。城外人的锁应该特殊处理
- mysql ping within mysql max idle time, my.cf wait_timeout show variables like '%timeout%'
- metrics of php request handling
- test callback php timeout
- test lock expiry
- March may need K
- alliance lock
- pprof may influnce performance
- mysql transaction with isolation repeatable read + optimistic locking has same effect
- I'd rather kill actor instead of mysqld
- what about distributed mysql instances?
- teleport
- Write/Read timeout and check N in loop
- can a player send N marches to the same tile?
- simulate mysql shutdown
- done! golang mysql driver with breaker will handle this
- WHERE UNIX_TIMESTAMP(time_end) index hit
- need to optimize DB index
- worker throttle
- we can't have toooo many callbacks concurrently, use channel for throttle, easy...
- handles NULL column
- march.type done if it's NULL, what about others?
- maybe we should let DB handle this
- but mysql enum datatype can't handle this automatically
- tsung 20M rows in db, and try actor
