+# For large tables, PostgreSQL can take a long time to count rows due to MVCC.
+# Implements a distinct and ordinary batch counter
+# Needs indexes on the column below to calculate max, min and range queries
+# For larger tables just set use higher batch_size with index optimization
+# See https://gitlab.com/gitlab-org/gitlab/-/merge_requests/22705
+# Examples:
+#  extend ::Gitlab::Database::BatchCount
+#  batch_count(User.active)
+#  batch_count(::Clusters::Cluster.aws_installed.enabled, :cluster_id)
+#  batch_distinct_count(::Project, :creator_id)
