 With the `import file` command, you can import data from [CSV]{% if lang == "ru" %}(https://ru.wikipedia.org/wiki/CSV){% endif %}{% if lang == "en" %}(https://en.wikipedia.org/wiki/Comma-separated_values){% endif %} or [TSV]{% if lang == "ru" %}(https://ru.wikipedia.org/wiki/TSV){% endif %}{% if lang == "en" %}(https://en.wikipedia.org/wiki/Tab-separated_values){% endif %} files to an existing table.
 
+Data from an imported file is read in batches whose size is set in the `--batch-bytes` option. An independent query is used to write each batch to the database. The queries are executed asynchronously. When the number of executed queries reaches `--max-in-flight`, reading from the file pauses. You can import data from multiple files using a single command. In this case, data from the files will be read asynchronously.
+
 The command implements the `BulkUpsert` method, which ensures high efficiency of multi-row bulk upserts with no atomicity guarantees. The upsert process is split into multiple independent parallel transactions, each covering a single partition. When completed successfully, it guarantees that all data is upserted.
 
 If the table already includes data, it's replaced by imported data on primary key match.
