Batched inserts to LSM-based databases aren't so uncommon. For example, ClickHouse expects batched writes - https://clickhouse.com/docs/en/optimize/bulk-inserts . Of course, it supports asynchronous inserts with in-memory buffering for the recently stored data - https://clickhouse.com/docs/en/cloud/bestpractices/asynchron...


Yes, that's true. And not even ClickHouse considers their MergeTree engine to be an LSM-tree (see https://github.com/ClickHouse/ClickHouse/blob/bfc0260f359a0c...).

That doesn't make it wrong, or a bad architecture. It still takes ideas from LSM-trees, and it has similarities. But it can't be called an LSM-tree.
