+# The 'maxmemory' directive controls the maximum amount of memory Redis is allowed to use.
+# Setting 'maxmemory 0' means there is no limit on memory usage, allowing Redis to use as much
+# memory as the operating system allows. This is suitable for environments where memory
+# constraints are not a concern.
+#
+# Alternatively, you can specify a limit, such as 'maxmemory 15gb', to restrict Redis to
+# using a maximum of 15 gigabytes of memory.
+#
+# Example:
+# maxmemory 0         # Unlimited memory usage
+# maxmemory 15gb     # Limit memory usage to 15 GB
+
+maxmemory 0
+
+# maxmemory-policy allkeys-lru
+#
+# This setting determines how Redis evicts keys when it reaches the memory limit.
+# 'allkeys-lru' evicts the least recently used keys from all keys stored in Redis,
+# allowing frequently accessed data to remain in memory while older data is removed.
+#
+# Example:
+# maxmemory-policy allkeys-lru  # Use LRU eviction for all keys
+
