+This page presents the consistency model used by the {server-name} and
+points to the tools built around it.
+
+== Data Replication
+
+The {server-name} relies on different storage technologies, all having their
own
+consistency models.
+
+These data stores replicate data in order to enforce some level of
availability. We call
+this process replication. By consistency, we mean the ability for all replica
to hold the
+same data. By availability, we mean the ability for a replica to answer a
request.
+
+In distributed systems,
link:https://en.wikipedia.org/wiki/CAP_theorem[according to the CAP theorem],
+as we will necessarily encounter network partitions, then trade-offs need to
be made between
+consistency and availability.
+
+This section details this trade-off for data stores used by the {server-name}.
+
+=== OpenSearch consistency model
+
+OpenSearch relies on

consistency]
+with home grown algorithm.
+
+The 6.x release line, that the distributed server is using is known to be slow
to recover from failures.
Review Comment:
6.x sounds like old es version and not opensearch ^^'
