I have about 60 billion records recorded. It has an average size of 980 GB and all in text file. (lines similar to md5 code)
Is it possible to transfer them to database?
I wonder if I run into a problem!
Of course it's possible. You will need to write a script to load the data from whatever format it is in inside your text file into SQL that can be executed against the database server.
The problems you are likely to run into:

If you are using auto-increment, make sure you make it a bigint.

It will take a long time to load.


To achieve reasonable performance, your loading program should use a prepared statement with bound parameters and commit in batches of 1000-10000.
On a modern server with high clock speed and NVMe storage, you might see 10,000 INSERTs per second. At that speed it will take you about 70 days to load your data set.
To mitigate failures, you should probably look into creating the table partitioned and splitting the loading into batches in such a way that each batch goes into a different partition. That way if a batch fails, you can truncate that one partition and re-run the failed batch.
If you are not familiar with databases and working with data at this scale, you should probably seriously consider hiring a professional with such experience to help you out with this for the ~3 months (or possibly as little as a few weeks, depending on how well stocked their bag of tricks is) it'll take to parse and load all of that data.
