How to use spring data redis pipeline to process 1 million records?

阅读更多关于 How to use spring data redis pipeline to process 1 million records?

问题 I have a requirement where I have to read a file which contains around 1 million records each record in a separate line. Each record will be validated and then will be saved in Redis cache. I implemented this in a normal traditional way by reading each line and saving it in the Redis cache but it is hampering performance very badly. Then I came to know about Redis pipeline feature in which I will process records in a batch say 10k at a time in order to improve performance . How can I use this

Can Redis write out to a database like PostgreSQL?

阅读更多关于 Can Redis write out to a database like PostgreSQL?

问题 I've been using PostgreSQL for the longest time. All of my data lives inside Postgres. I've recently looked into redis and it has a lot of powerful features that would otherwise take a couple of lines in Django (python) to do. Redis data is persistent as long the machine it's running on doesn't go down and you can configure it to write out the data it's storing to disk every 1000 keys or every 5 minutes or so depending on your choice. Redis would make a great cache and it would certainly

Why are connections to Azure Redis Cache so high?

阅读更多关于 Why are connections to Azure Redis Cache so high?

问题 I am using the Azure Redis Cache in a scenario of high load for a single machine querying the cache. This machine roughly gets and sets about 20 items per second. During daytime this increases, during nighttime this is less. So far, things have been working fine. Today I realized that the metric of "Connected Clients" is extremely high, although I only have 1 client that just constantly Gets and Sets items. Here is a screenshot of the metric I mean: My code looks like this: public class
