look into a series of the blog posts that I sent, I think that it should be
in the 4th post

okay, is there a way to export the TTL using CQLsh or DSBulk?

if you didn't export TTL explicitly, and didn't load it back, then you'll
get not expirable data.

In tried verify metadata, In case of writetime it is setting it as insert
time but the TTL value is showing as null. Is this expected? Does this mean
this record will never expire after the insert?
Is there any alternative to preserve the TTL ?
In the new Table inserted with Cqlsh and Dsbulk
cqlsh
thank you

Alex is referring to the "writetime" and "tttl" values for each cell. Most
tools copy via CQL writes and don't by default copy those previous
writetime and ttl values and instead just give a new writetime value which
matches the copy time rather than initial insert time.

Hello Alex,
- use DSBulk - it's a very effective tool for unloading & loading data
from/to Cassandra/DSE. Use zstd compression for offloaded data to save disk
space (see blog links below for more details). But the *preserving
metadata* could be a problem.
Here what exactly do you me
Thank you for the suggestions

CQLSH definitely won't work for that amount of data, so you need to use
other tools.
But before selecting them, you need to define requirements. For example:
1. Are you copying the data into tables with exactly the same structure?
2. Do you need to preserve metadata, like, writetime & TTL?
I wouldn't say it's good approach for that size. But you can try dsbulk
approach too.
Try to split output into multiple files.
