remove ttl in rdb file?

[Joel VanderKwaak]

Howdy,

I have an rdb file from last year, and the interesting keys have TTLs of 60 days.

They are purged soon after loading the data into redis.

Is there any way to:
1. configure redis to ignore TTLS
2. or reset TTLs without loading the file into redis.

Thanks,

Joel

You can use redis-rdb-tools and a small python script to solve this problem.

1. Parse the RDB and load objects in python
2. Store the object in redis by discarding the expiry information

Here is a short script demonstrating the idea. This depends on redis-rdb-tools and redis-py libraries available.

from rdbtools import RdbParser, RdbCallback

from redis import StrictRedis

class MyCallback(RdbCallback):

    def __init__(self):

        super(MyCallback, self).__init__(string_escape=None)

        # Redis connection where we will write the objects read from rdb

        self.red = StrictRedis()

    def set(self, key, value, expiry, info):

        # discard expiry and just write key=value into redis

        self.red.set(key, value)

    

    # depending on the data types you use, you will have to override other similar methods    

def main():

    callback = MyCallback()

    parser = RdbParser(callback)

    # path to the rdb file you want to parse

    parser.parse('dump.rdb')

if __name__ == '__main__':

    main()
