Recovery Test

Dependencies:

To run the codes in this repo, you should have the following:

• g++ support C++17 standard

• Redis

• Mysql

• redis-plus-plus client

• MySQL Connector/C++ (8.0)

Notices:

• Since we need to test Redis recovery performance, we need to disable Redis persistence, which can be done by setting set "" in redis.conf.
• To use MySQL Connector/C++ x DevAPI, we need X Plugin enabled for MySQL, which is by default in MySQL 8.

Usage:

• python3 gen.py: generate initial file.

• make: compile the source code into an executable file.

• ./run.sh [user] [password]: run the experiment.

  [user] and [password] stand for the username and password to connect to MySQL server. Note that we need a user to have privileges for tables.

• python3 plot.py: plot the data and save it.

Result:

The current data size is about 512MB with 2M key-value pairs, each pair 256B.

50%read, 50%update, RDB off:

90%read, 10%update, RDB off:

We crash the redis server at 1 min, 2 min, 4 min and 8 min.

Conclusions:

• The performance fluctuates a lot on the VM. We may take the key-value pair smaller.

Week Plan:

• Improve the existing experiment to get better result.

• Read the Phoenix kernel and user api code.
