Namespace configuration

This page describes high-level considerations for configuring an Aerospike namespace, and contains links to relevant pages.

Requirements

Namespace name

The minimum requirement to configure a namespace is to provide a namespace name. The following example creates an in-memory namespace with a 4GB capacity. The commented parameters indicate the defaults.

namespace <namespace-name> {
    # memory-size 4G           # 4GB of memory to be used for index and data
    # replication-factor 2     # For multiple nodes, keep 2 copies of the data
    # high-water-memory-pct 60 # Evict non-zero TTL data if capacity exceeds
                               # 60% of 4GB
    # stop-writes-pct 90       # Stop writes if capacity exceeds 90% of 4GB
    # default-ttl 0            # Writes from client that do not provide a TTL
                               # will default to 0 or never expire
    # storage-engine memory    # Store data in memory only
}

Where to Next?

• Storage engine which determines if and where records are persisted to.
• Data retention policy which determines how long records are kept after it is initially written.
• Data durability policy which determines how many replica copies of a record to keep in the cluster.
• Configure strong consistency which describes how to set up SC mode for transactions.
• For a complete list of namespace configuration parameters see the Configuration reference.
