Vector index creation is known to be slow. To speed the process up, index creation can be parallelized. The maximum number of threads can be
configured using server configuration
setting [max_build_vector_similarity_index_thread_pool_size](../../../operations/server-configuration-parameters/settings.md#server_configuration_parameters_max_build_vector_similarity_index_thread_pool_size).
ANN indexes are built during column insertion and merge. As a result, `INSERT` and `OPTIMIZE` statements will be slower than for ordinary
tables. ANNIndexes are ideally used only with immutable or rarely changed data, respectively when are far more read requests than write

Notes:
1. Older versions of ClickHouse might not support the syntax of multiple authentication methods. Therefore, if the ClickHouse server contains such users and is downgraded to a version that does not support it, such users will become unusable and some user related operations will be broken. In order to downgrade gracefully, one must set all users to contain a single authentication method prior to downgrading. Alternatively, if the server was downgraded without the proper procedure, the faulty users should be dropped.
2. `no_password` can not co-exist with other authentication methods for security reasons.
Because of that, it is not possible to `ADD` a `no_password` authentication method. The below query will throw an error:
``` sql
ALTER USER user1 ADD IDENTIFIED WITH no_password
```
If you want to drop authentication methods for a user and rely on `no_password`, you must specify in the below replacing form.
Reset authentication methods and adds the ones specified in the query (effect of leading IDENTIFIED without the ADD keyword):
