async_* MergeTree table settings

These settings are available in system.merge_tree_settings and are autogenerated from ClickHouse source.

async_block_ids_cache_update_wait_ms

Deprecated alias of deduplication_hashes_cache_update_wait_ms, kept for one release for backward compatibility. It is honored only when deduplication_hashes_cache_update_wait_ms is left at its default; this setting will be removed in a future release.

async_insert

If true, data from INSERT query is stored in queue and later flushed to table in background.
