私は、次のドキュメントを参照しています：
https://redis.io/topics/distlock
https://github.com/mike-marcacci/node-redlock
var redis = require('redis');
var Redlock = require('redlock');
var redisClient = redis.createClient(settings.redisport, settings.redishost);
var redlock = new Redlock(
// you should have one client for each independent redis node
// or cluster
[redisClient],
{
// the expected clock drift; for more details
// see http://redis.io/topics/distlock
driftFactor: 0.01, // time in ms
// the max number of times Redlock will attempt
// to lock a resource before erroring
retryCount: 10,
// the time in ms between attempts
retryDelay: 200, // time in ms
// the max time in ms randomly added to retries
// to improve performance under high contention
// see https://www.awsarchitectureblog.com/2015/03/backoff.html
retryJitter: 200 // time in ms
}
);
redlock.lock([Key], settings.lockttl).then(function (lock) {
return lock.unlock();
}).catch(function (err) {
return lock.unlock();
});
