 ## Why is my query slow?
 
 Query performance depends on time range and complexity.
 If a query is slower than you expect, it might be due to the following reasons:
 
-- It queries data from a  large time range.
+- It queries data from a large time range.
 - It includes intensive operations, such as querying many string values or `ORDER BY` sorting or re-sorting large amounts of data.
 
 ## Strategies for improving query performance
 
 The following design strategies generally improve query performance and resource use:
 
 - Follow [schema design best practices](/influxdb/cloud-dedicated/write-data/best-practices/schema-design/) to make querying easier and more performant.
-- Query only the data you need--for example, include a [`WHERE` clause](/influxdb/cloud-dedicated/reference/sql/where/) that filters data by a time range.
-  InfluxDB v3 stores data in a Parquet file for each measurement and day, and retrieves files from the Object store to answer a query.
-  The smaller the time range in your query, the fewer files InfluxDB needs to retrieve from the Object store.
+- [Query only the data you need](#query-only-the-data-you-need).
 - [Downsample data](/influxdb/cloud-dedicated/process-data/downsample/) to reduce the amount of data you need to query.

+### Query only the data you need
+
+#### Include a WHERE clause
+
+InfluxDB v3 stores data in a Parquet file for each partition.
+By default, {{< product-name >}} partitions tables by day, but you can also
+[custom-partition your data](/influxdb/cloud-dedicated/admin/custom-partitions/).
+At query time, InfluxDB retrieves files from the Object store to answer a query.
+To reduce the number of files that a query needs to retrieve from the Object store,
+include a [`WHERE` clause](/influxdb/cloud-dedicated/reference/sql/where/) that
+filters data by a time range or by specific tag values.
+
+#### SELECT only columns you need 
+
+Because InfluxDB v3 is a columnar database, it only processes the columns
+selected in a query, which can mitigate the query performance impact of
+[wide schemas](/influxdb/cloud-dedicated/write-data/best-practices/schema-design/#avoid-wide-schemas).
+
+However, a non-specific query that retrieves a large number of columns from a
+wide schema can be slower and less efficient than a more targeted
+query--for example, consider the following queries:
+
+- `SELECT time,a,b,c`
+- `SELECT *`
+
+If the table contains 10 columns, the difference in performance between the
+two queries is minimal.
+In a table with over 1000 columns, the `SELECT *` query is slower and
+less efficient.
