Class RedissonFasterMultiLock

java.lang.Object
org.redisson.RedissonObject
org.redisson.RedissonBaseLock
org.redisson.RedissonFasterMultiLock
All Implemented Interfaces:
Lock, RExpirable, RExpirableAsync, RLock, RLockAsync, RObject, RObjectAsync, RObservable, RObservableAsync
public class RedissonFasterMultiLock extends RedissonBaseLock
RedissonFasterMultiLock.
All lock, unlock, lockAsync unlockAsync methods only success when all values locked succeed.
Example:
there is a class, id is 100, and three students in class, Jack(id:001),Mary(id:002)
  • current thread id : 1
  • ServiceManager id: 71b96ce8-2746......
  • current time stamp: 1727422868000
when redissonBatchLock.lock("class_100",Arrays.asList("Jack_001","Mary_002")
It will be saved In redis like this: 
 -----------------------------------------------------------------------
 | redis type: hash                                                    |
 | redis Key: class_100                                                |
 -----------------------------------------------------------------------
 | field                                           | value             |
 -----------------------------------------------------------------------
 | Jack_001                                        | 71b96ce8-2746:1   |
 | Mary_002                                        | 71b96ce8-2746:1   |
 | Jack_001:71b96ce8-2746:1:expire_time            | 1,727,422,898,000 |
 | Jack_001:71b96ce8-2746:1:lock_count             | 1                 |
 | Mary_002:71b96ce8-2746:1:expire_time            | 1,727,422,898,000 |
 | Mary_002:71b96ce8-2746:1:lock_count             | 1                 |
 -----------------------------------------------------------------------
Attention: the value of group should be `smallest`, in our example above , group should be 'class_100' not just 'class'
Of course the values `Jack_001`,`Mary_002` will be encoded and hashed.
