Thx=2C kathleen. This is my understanding. If I config initLimit=3D10 and s=
yncLimit=3D3=2C so as follow: 1. Leader will wait for follow 10*tickTime to=
 do such things: connect to leader=2C  and sync the lasted data from leader=
. But=2C if the time follow load snap data from local disk is included in 1=
0*tickTime? =0A=
=0A=
=0A=
 =0A=
  =0A=
  Load snap data from local disk=0A=
  =0A=
  =0A=
  Conn to leader=0A=
  =0A=
  =0A=
  Sync lasted data from leader=0A=
  =0A=
 =0A=
   A: load snap data from local disk=2CB: conn to leaderC: sync lasted data=
 from leader. Maybe=2C you can tell me=2C  10*tickTime includes whick part?=
 A   or  B+C or A+B+C 2. While in runtime=2C if follow's state too far behi=
nd a leadr=2C even to 3*tickTime=2C the follow will be dropped.  Others=2C =
please check my understanding=2C thx!  Charles   =20
