Redis Managed Database

How is it going so far with your managed redis? How does it perform under high load?

So far, I am a little disappointed that we are not able to switch Redis Persistence off (for performance reasons). The only configuration we have access to is Eviction Policy.

Hello Everyone

I just finished the migration from Redis single instance to DO Redis Managed Database, everything went smooooooth :)

In case someone interested to copy his Redis data to another Redis server (aka DO Redis managed database) the below script will help you to do that

if [ $# -eq 0 ]; then
  echo "select a db"
  exit 1
fi

export DBnumber="$1"

echo "DB ${DBnumber}"

export OLD="redis-cli -n ${DBnumber}"
export NEW="redis-cli -n ${DBnumber} -p MYPORT -a PASSWORD"


for KEY in $($OLD --scan); do
    $OLD --raw DUMP "$KEY" | head -c-1 > /tmp/dump
    TTL=$($OLD --raw TTL "$KEY")
    case $TTL in
        -2)
            $NEW DEL "$KEY"
            ;;
        -1)
            $NEW DEL "$KEY"
            cat /tmp/dump | $NEW -x RESTORE "$KEY" 0
            ;;
        *)
            $NEW DEL "$KEY"
            let TTLEX="$TTL*1000"
            cat /tmp/dump | $NEW -x RESTORE "$KEY" "$TTLEX"
            ;;
    esac
    echo "$KEY (TTL = $TTL)"
done

Hey,

Quick update here in case that anyone comes across this in the future, DigitalOcean has just announced two new features to the Managed Database for Redis offering:

1. The ability to add up to two additional nodes to your existing cluster

2. Support for using standby nodes to serve read requests

Both of these features offer increased scalability, enhanced performance, and improved availability of the managed Redis clusters and applications.
