Hi, Igntrs!

I would like to implement suspend\resume methods of a pessimistic
transaction as following:

if transaction holds lock on a key and suspend method has been called no
keys would be unlocked. Therefore,

if transaction holds lock on a key and suspend method has been called,
topology changing (e.g. start new node in the same thread) would wait
transaction to be resumed and finished.

Do you think it=E2=80=99s an appropriate behavior?


=D0=BF=D1=82, 13 =D0=BE=D0=BA=D1=82. 2017 =D0=B3. =D0=B2 5:06, Dmitriy Setr=
