Aptible supports replication or clustering for a number of Databases:
Aptible supports creating read-only replicas for Redis.
Aptible supports read-only hot standby replicas for PostgreSQL databases. PostgreSQL replicas utilize a replication slot on the primary database which may increase WAL file retention on the primary. We recommend using a Metric Drain to monitor disk usage on the primary database.
Aptible supports creating replicas for MySQL databases. While these replicas do not prevent writes from occurring, Aptible does not support writing to MySQL replicas. Any data written directly to a MySQL replica (and not the primary) may be lost.
Aptible supports creating MongoDB replica sets. To ensure that your replica is fault tolerant, you should follow the MongoDB recommendations for number of instances in a replica set when creating a replica set. We also recommend that you review the readConcern, writeConcern and connection url documentation to ensure that you are taking advantage of useful features offered by running a MongoDB replica set.
Replicas can be created for supported databases using the
aptible db:replicate command.
Creating a replica on Aptible has a 6 hour timeout. While most databases can be replicated in under 6 hours, some very large databases may take longer than 6 hours to create a replica. If your attempt to create a replica fails after hitting the 6 hour timeout, reach out to Aptible Support.
