+
+## Query time de-duplication & FINAL
+
+At merge time, the ReplacingMergeTree identifies duplicate rows, using the values of the `ORDER BY` columns (used to create the table) as a unique identifier, and retains only the highest version. This, however, offers eventual correctness only - it does not guarantee rows will be deduplicated, and you should not rely on it. Queries can, therefore, produce incorrect answers due to update and delete rows being considered in queries.
+
+To obtain correct answers, users will need to complement background merges with query time deduplication and deletion removal. This can be achieved using the `FINAL` operator. For example, consider the following example:
+
+```sql
+CREATE TABLE rmt_example
+(
+    `number` UInt16
+)
+ENGINE = ReplacingMergeTree
+ORDER BY number
+
+INSERT INTO rmt_example SELECT floor(randUniform(0, 100)) AS number

+
+0 rows in set. Elapsed: 19.958 sec. Processed 1.00 billion rows, 8.00 GB (50.11 million rows/s., 400.84 MB/s.)
+```
+Querying without `FINAL` produces an incorrect count (exact result will vary depending on merges):
+
+```sql
+SELECT count()

+

+
+Adding final produces a correct result:

+┌─count()─┐
+│     100 │

+# quantileExactWeightedInterpolated
+
+Computes [quantile](https://en.wikipedia.org/wiki/Quantile) of a numeric data sequence using linear interpolation, taking into account the weight of each element.
+
+To get the interpolated value, all the passed values are combined into an array, which are then sorted by their corresponding weights. Quantile interpolation is then performed using the [weighted percentile method](https://en.wikipedia.org/wiki/Percentile#The_weighted_percentile_method) by building a cumulative distribution based on weights and then a linear interpolation is performed using the weights and the values to compute the quantiles.
+
+When using multiple `quantile*` functions with different levels in a query, the internal states are not combined (that is, the query works less efficiently than it could). In this case, use the [quantiles](../../../sql-reference/aggregate-functions/reference/quantiles.md#quantiles) function.
+
+We strongly recommend using `quantileExactWeightedInterpolated` instead of `quantileInterpolatedWeighted` because `quantileExactWeightedInterpolated` is more accurate than `quantileInterpolatedWeighted`. Here is an example:
+
+``` sql
+SELECT

+## Using S3 credentials (ClickHouse Cloud)
+
+For non-public buckets, users can pass an `aws_access_key_id` and `aws_secret_access_key` to the function. For example: 
+
+```sql
+SELECT count() FROM s3('https://datasets-documentation.s3.eu-west-3.amazonaws.com/mta/*.tsv', '<KEY>', '<SECRET>','TSVWithNames')
+```
+
+This is appropriate for one-off accesses or in cases where credentials can easily be rotated. However, this is not recommended as a long-term solution for repeated access or where credentials are sensitive. In this case, we recommend users rely on role-based access.
+
+Role-based access for S3 in ClickHouse Cloud is documented [here](/docs/en/cloud/security/secure-s3#access-your-s3-bucket-with-the-clickhouseaccess-role).
+
+Once configured, a `roleARN` can be passed to the s3 function via an `extra_credentials` parameter. For example:
+
+```sql
+SELECT count() FROM s3('https://datasets-documentation.s3.eu-west-3.amazonaws.com/mta/*.tsv','CSVWithNames',extra_credentials(role_arn = 'arn:aws:iam::111111111111:role/ClickHouseAccessRole-001'))
+```
+
+Further examples can be found [here](/docs/en/cloud/security/secure-s3#access-your-s3-bucket-with-the-clickhouseaccess-role)
