Live memory resizing

​

Turn it on

import { Template } from "@superserve/sdk"

const template = await Template.create({
  name: "my-growable-env",
  memoryMib: 2048,
  memoryMaxMib: 8192,
  from: "python:3.11",
})

from superserve import Template

template = Template.create(
    name="my-growable-env",
    memory_mib=2048,
    memory_max_mib=8192,
    from_="python:3.11",
)

How it works

• Growing: when a sandbox runs low on memory, it grows automatically, up to its limit. A program can even ask for a large block of memory at once, more than the sandbox started with, and the sandbox grows as the program uses it.
• Shrinking: once the burst is over and memory use has stayed low for a few minutes, the sandbox shrinks to fit what it’s using. It never goes below memoryMib.
• Pause, resume and snapshots: a sandbox resumes at the size it was paused at, and a sandbox created from a snapshot starts at its source’s size.
• Above the limit: if a program needs more than memoryMaxMib, Linux stops that program, as on any machine that runs out of memory. The sandbox keeps running.

Check the current size

const info = await sandbox.getInfo()
console.log(info.memoryMib, info.memoryMaxMib, info.memoryCurrentMib)

info = sandbox.get_info()
print(info.memory_mib, info.memory_max_mib, info.memory_current_mib)
