How dose ignite implement concurrent control in transaction?
hi , How dose ignite implement concurrent control in transaction?
Since Ignite support Read Repeat isolation,so in a transaction lock protocol
is tow phase with respect to exclusive lock and well-formed. Does Ignite
implement tow phase lock and granule lock to prevent phantom read.Besides
Dose Ignite support granular locks and intend lock?

hi Dmitriy Pavlov ,
thanks for your reply,
I read the doc , and I find that in RR isolation ,there is just one kind of
lock.
So Ignite dose not support share lock ? And dose Ignite not support granule
lock?
