Add a X-clickhouse-summary Header When We Send a Query Using HTTP with Enabled Setting Send_progress_in_http_headers
Add a X-ClickHouse-Summary header when we send a query using HTTP with enabled setting send_progress_in_http_headers. Return the usual information of X-ClickHouse-Progress, with additional information like how many rows and bytes were inserted in the query. #5116 (Guillaume Tassery)Why it matters
This feature enhances HTTP query responses by including a summary header that shows not only the usual progress details but also additional metrics like the number of rows and bytes inserted during the execution of an insert query. This helps users monitor query execution and data ingestion more precisely via HTTP.How to use it
Enable the settingsend_progress_in_http_headers in your HTTP query requests to receive the X-ClickHouse-Summary header in the server's response. This header will contain progress information along with insertion statistics if applicable.
