Ethereum: Safe interruption of reintex
As a user of Ethereum Blockchain, it is probably unknown to the challenges associated with a safe and most recent database. Recently, we experienced a situation in which our database was damaged during reintext, which led to a significant and increased use of the CPU.
Question: Repeat Big Database
Reintexation is a process used by many blockchain platforms, including Ethereum, updates the database with new data from external sources. When filling in Reindex, users usually use a command line interface (cli), such as bitcoind – -daemon -reindex. This team allows them to intervene manually in the reintext process.
However, in our case, we faced an unexpected problem that had to be safely interrupted by the reintext process. The problem was caused by the excessive use of the processor and the long -term time, which eventually damaged the corruption of data.
Why reintexation can be intense
Reintexation is not an insignificant task. This includes updating the entire database using new data from external sources, such as blockchains or API. This process requires significant calculation resources including:
* processor power : Reintexation can consume a high processor capacity, especially when exposed to large data sets.
* Memory permeability
: Significant restriction is also the amount of memory required for storing and processing updated data.
Solution: Safe withdrawal of reintexation
To avoid similar questions in the future, we recommend that you take the following precautions:
- If it exceeds a certain threshold (eg 80% 30 minutes), turn off the process to avoid excessive resources.

As part of these guidelines, you will be able to safely conclude rendexation and prevent data corruption, while maintaining a smooth user experience.
Example of case use:
Here is an example of how you can safely break the reindication using the Bitcoind Cli tool:
`Bash
Begins Deemon starting reintexation
Bitcoind --daemon -reindex
Note the use of the processor and turn off the rendex if it exceeds 80%
Although true; to do
cpu_usage = $ (top -bn1 | awk '/ cpu/ {print $ 4}' | grap -op '(? <= "user") [^"]*'))
if [$ cpu_usage -gt 80]; Then
Using the Echo processor ”exceeds 80%! Interruption.
a break
be
made
Continue the original order (eg launch the knot and wait for it)

Conclusion
The process of reintext of Ethereum can be complicated, but following safe interruption guidelines and using special assemblies or large data sets, you can prevent data damage and maintain a user experience.
