Azat Khuzhin	32a45d0dee	Implement lifetime_rows/lifetime_bytes for Buffer engine ... Buffer engine is usually used on INSERTs, but right now there is no way to track number of INSERTed rows per-table, since only summary metrics exists: - StorageBufferRows - StorageBufferBytes But it can be pretty useful to track INSERTed rows rate (and it can be exposed via http_handlers for i.e. prometheus)	2020-07-11 16:06:11 +03:00
