About Hosting ScyllaDB 5.1.4

ScyllaDB 5.1.4 lets you deploy ScyllaDB with version locked to v5.1.4.

Common Use Cases

• Dealing with high traffic that quite frequently read/write to the DB.
• When using it via Railway's private network is a must otherwise it's recommended to use ScyllaDB template instead.

Implementation Details

Quick Start Guide

• Add a project as new service
• Edit a service's configuration to point to scylla's private domain (or scylla's railway public domain). You can find these value from these special variables (Can be found on ScyllaDB service -> Variables tab):
  • $SCYLLA_HOST
  • $SCYLLA_PORT
  • $SCYLLA_PRIVATE_HOST
  • $SCYLLA_PRIVATE_PORT
• Your service(s) should now be connected to the ScyllaDB

Known Issues

• If your service(s) can't connect to scylla using its private network domain, try shorten the domain. For example my ScyllaDB service use scylladb.railway.internal private domain, instead of using the full scylladb.railway.internal you remove the .railway.internal suffix so it just says scylladb.

Environment Variables

• MEM: Memory limit, default: 2G
• SMP: Restricts ScyllaDB to N logical cores, default: 2
• LISTEN_ADDR: ScyllaDB's listen address, default: :: (You can set this to 0.0.0.0 for IPv4 support)
• API_ADDR: ScyllaDB's Rest API address, default: :: (You can set this to 0.0.0.0 for IPv4 support)

Special Environment Variables

• SCYLLA_HOST: You can use this variable's value to connect your software to ScyllaDB. You can also use it to connect to ScyllaDB from you favorite DB (Cassandra-compatible) client
• SCYLLA_PORT: You can use this variable's value to connect your software to ScyllaDB. You can also use it to connect to ScyllaDB from you favorite DB (Cassandra-compatible) client
• SCYLLA_PRIVATE_HOST: You can use this variable's value to connect your software to ScyllaDB (Through Railway's Private Network, requires IPv6)
• SCYLLA_PRIVATE_PORT: You can use this variable's value to connect your software to ScyllaDB (Through Railway's Private Network, requires IPv6)
