+Limits the number of Parquet files a query can access.
+
+**Default:** `432`
+
+With the default `432` setting and the default [`gen1-duration`](#`gen1-duration`)
+setting of 10 minutes, queries can access up to a 72 hours of data, but
+potentially less depending on whether all data for a given 10 minute block of
+time was ingested during the same period.
+
+You can increase this limit to allow more files to be queried, but be aware of
+the following side-effects:
+
+- Degraded query performance for queries that read more Parquet files
+- Increased memory usage
+- Your system potentially killing the `influxdb3` process due to Out-of-Memory
+  (OOM) errors
+- If using object storage to store data, many GET requests to access the data
+  (as many as 2 per file)
+
+> [!Note]
+> We recommend keeping the default setting and querying smaller time ranges.
+> If you need to query longer time ranges or faster query performance on any query
+> that accesses an hour or more of data, [InfluxDB 3 Enterprise](/influxdb3/enterprise/)
+> optimizes data storage by compacting and rearranging Parquet files to achieve
+> faster query performance.
