Snapshot configuration

`[snapshot]`

Snapshot lifetimes, quotas and preparation.

[snapshot]
default_lifetime = "1h"
max_lifetime = "30days"

`snapshot.default_lifetime`

non-zero durationrestart to apply

The lifetime of a Snapshot created without snapshotLifetime.

Default: "1h"
Must be: 0 < default_lifetime ≤ snapshot.max_lifetime
Environment variable: ANDROMEDA__SNAPSHOT__DEFAULT_LIFETIME

`snapshot.max_lifetime`

non-zero durationrestart to apply

The longest a Snapshot lives. A longer requested snapshotLifetime is cut down to this.

Default: "30days"
Must be: 0 < max_lifetime
Environment variable: ANDROMEDA__SNAPSHOT__MAX_LIFETIME

`[snapshot.quota]`

How many Snapshots, and how much storage, one tenant may keep.

[snapshot.quota]
max_per_tenant = "unlimited"
max_storage_per_tenant = "unlimited"

`snapshot.quota.max_per_tenant`

string or positive integerrestart to apply

The most Snapshots one tenant keeps, or "unlimited" to keep any number.

Default: "unlimited"
Allowed values: "unlimited"No limit.
Environment variable: ANDROMEDA__SNAPSHOT__QUOTA__MAX_PER_TENANT

`snapshot.quota.max_storage_per_tenant`

string or sizerestart to apply

The most storage one tenant's Snapshots take, or "unlimited" to let them take any amount.

Default: "unlimited"
Allowed values: "unlimited"No limit.
Must be: 0 < max_storage_per_tenant
Environment variable: ANDROMEDA__SNAPSHOT__QUOTA__MAX_STORAGE_PER_TENANT

`[snapshot.preparation]`

How a Snapshot is prepared.

[snapshot.preparation]
page_size = 250
max_concurrent = 4
lease_timeout = "30s"
recovery_interval = "30s"
scoped_operation_timeout = "20s"

`snapshot.preparation.page_size`

positive integerrestart to apply

The results read per page while a Snapshot captures its content.

Default: 250
Must be: 0 < page_size
Environment variable: ANDROMEDA__SNAPSHOT__PREPARATION__PAGE_SIZE

`snapshot.preparation.max_concurrent`

positive integerrestart to apply

The most Snapshots prepared at once.

Default: 4
Must be: 0 < max_concurrent
Environment variable: ANDROMEDA__SNAPSHOT__PREPARATION__MAX_CONCURRENT

`snapshot.preparation.lease_timeout`

non-zero durationrestart to apply

How long a claim keeps a preparation from every other worker before another may take it over.

Default: "30s"
Must be: 0 < lease_timeout
Environment variable: ANDROMEDA__SNAPSHOT__PREPARATION__LEASE_TIMEOUT

`snapshot.preparation.recovery_interval`

non-zero durationrestart to apply

How often preparations a crash or a missed run left unfinished are resumed. Creating a Snapshot starts preparing it at once, so this sweep only recovers.

Default: "30s"
Must be: 0 < recovery_interval
Environment variable: ANDROMEDA__SNAPSHOT__PREPARATION__RECOVERY_INTERVAL

`snapshot.preparation.scoped_operation_timeout`

non-zero durationrestart to apply

How long a request scoped to a Snapshot waits for its capture or clone to finish. A request still waiting then is answered 503 with Retry-After.

Default: "20s"
Must be: 0 < scoped_operation_timeout < request_limits.timeout
Environment variable: ANDROMEDA__SNAPSHOT__PREPARATION__SCOPED_OPERATION_TIMEOUT
