QUESTION
I want to know how to recover Scalar DB to another instance using Cassy backup. Because I need a new instance for tests from the production environment.
...ANSWER
Answered 2020-Oct-13 at 04:30There is no direct support in Cassy to load backups that were taken in a cluster to another cluster. Since Cassy only manages snapshots of Cassandra, you can follow the doc to do it.
For testing, I would recommend dumping some of the data from the current (possibly production) cluster and load it to a new testing cluster.

QUESTION
i want to know the characteristics of Cassy backup and how to use them in actual operation. Specifically, from an operational design perspective, what is the difference between snapshots and consistent backups, what types of usage patterns can you use each or in combination, and what are the benefits and tradeoffs?
...ANSWER
Answered 2020-Jul-31 at 12:36Both are snapshot. Consistent snapshot (a.k.a cluster-wide snapshot/backup) is a special snapshot that is transactionally consistent. Imagine a transaction T in a payment application. T: sends $100 from an account A to an account B. T actually has 2 processes like deducting $100 from A's account and adding $100 to B's account.
If you take a normal snapshot, the transaction is not cared so a produced snapshot might not have the result of one of the processes. Instead, transactionally consistent snapshot is either a snapshot before or after the transaction occurs.
Transactionally consistent backup is useful only when quorum of C* disks are broken and the data is lost. Otherwise, normal snapshot is enough since C* cluster still has quorum of data alive and the latest data can just be synchronized.
Snapshot should be taken regularly like once in a week or 2 weeks. Cluster-wide snapshot can be taken in a longer time span just for the worst case scenario.

QUESTION
I have a dataset which contains employee id, name and their bank account information. Some of these employees have duplicate names with either same employee id or different employee id for same employee name. Few of these employees also have same bank account information for same names while some have different bank account numbers under same name. The aim is to find those employees who have same name but different bank account number. Here's a sample of the data:

QUESTION
I need to calculate the day-1 retention by user registration date. Day-1 retention is defined as the number of users who return 1 day after the registration date divided by the number of users who registered on the registration date.
Here's the user table
...ANSWER
Answered 2019-May-22 at 08:58I am not quiet sure if this is your expected result:
For registrationdate = 2018-01-01 all two users have been logged within the first day, so the result is 1. For registrationdate = 2018-01-02 only one of two users have been logged within this range, so the result is 0.5

QUESTION
I'm trying to make a program that draws certain lines based on user input.
...ANSWER
Answered 2017-Jun-14 at 22:01Your issue is not really with the exec call, but with the value you're passing as its argument. When you do line.get(draw), you lookup the value of the variable draw in the line dictionary. If that value doesn't exist (as it won't if draw is a multi-character string), you get None. Running exec(None) gives you the TypeError you're seeing.
I have several suggestions for ways to fix this issue. Which ones you'll want to follow may depend on what behavior you want from your program.
To start with, I suggest using brackets to index your dictionary, rather than the get method. This will change the error you get from a TypeError (from exec) to a KeyError from the dictionary. That's still an exception, but it at least points more accurately at the cause of the issue (the string being looked up is not in the dictionary).
The next suggestion is to check for a multi-character string before trying to look it up, and report an error to the user. You can check if len(draw) is equal to 1, and only run the rest of the code if it is. I'd put this check at the same place as the current check you have for alphanumeric characters.
Here's what those two fixes would look like together:

Install cassy
You can use cassy like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the cassy component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
