# ClickHouse Features that Can be Considered Disadvantages
|
|
|
|
1. Lack of full transactions.
|
|
2. Previously recorded data can't be changed or deleted with low latency and high query frequency. Mass deletions to clear data that is no longer relevant or falls under [GDPR](https://gdpr-info.eu) regulations. Batch changes to data are in development (as of July, 2018).
|
|
3. The sparse index makes ClickHouse ill-suited for point-reading single rows on its own keys.
