-Async Replication is a background synchronization process in Weaviate that ensures eventual consistency across nodes storing the same shard. When a collection is partitioned into multiple shards, each shard is replicated across several nodes (as defined by the replication factor `REPLICATION_MINIMUM_FACTOR`). Async replication guarantees that all nodes holding the same shard remain in sync by periodically comparing and propagating data.
+Async replication is a background synchronization process in Weaviate that ensures eventual consistency across nodes storing the same shard. When a collection is partitioned into multiple shards, each shard is replicated across several nodes (as defined by the replication factor `REPLICATION_MINIMUM_FACTOR`). Async replication guarantees that all nodes holding the same shard remain in sync by periodically comparing and propagating data.
 
 #### 1. Periodic data comparison
 
 Each node runs a background process that periodically compares its locally stored data with other nodes holding the same shard. This comparison is triggered either:
-- At regular intervals (`ASYNC_REPLICATION_FREQUENCY`).
-- When a change in availability of a node is detected (`ASYNC_REPLICATION_ALIVE_NODES_CHECKING_FREQUENCY`).
-
-To efficiently detect differences, Weaviate uses a **hashtree**. Instead of checking entire datasets, it compares hash digests at multiple levels, narrowing down differences to specific objects. The size of this hashtree can be defined via `ASYNC_REPLICATION_HASHTREE_HEIGHT`.
+- at **regular intervals** (`ASYNC_REPLICATION_FREQUENCY`) or
+- when a **change in the availability of a node** is detected (`ASYNC_REPLICATION_ALIVE_NODES_CHECKING_FREQUENCY`).
 
 If a node is unresponsive, Weaviate applies a timeout (`ASYNC_REPLICATION_DIFF_PER_NODE_TIMEOUT`) to avoid delays in the replication process.

 #### 2. Data synchronization
 
-When differences are detected, the outdated or missing data is propagated to the affected nodes. This propagation process:
-- Sends data in batches of a custom size (`ASYNC_REPLICATION_BATCH_SIZE`).
-- Limits each propagation step object limit (`ASYNC_REPLICATION_PROPAGATION_LIMIT`).
-- Enforces a time-bound for updates (`ASYNC_REPLICATION_PROPAGATION_TIMEOUT`).
-- Uses a different comparison frequency right after completing synchronization on a node (`ASYNC_REPLICATION_FREQUENCY_WHILE_PROPAGATING`).
