Module clusters 

Clusters apply command - converge live cluster state to match definitions.

Structs

CanonicalIntervals 🔒

Rewrites every interval-valued literal in an option to its canonical form, reaching nested values such as LINGER DURATION inside AUTO SCALING STRATEGY.

Functions

comparable 🔒

An option’s value reduced to a form the two sides of the diff can be compared by.

default_options 🔒

The options SHOW CREATE CLUSTER renders for every managed cluster, paired with the value the server assigns when the definition omits them.

diff_cluster_options 🔒

Compare a cluster definition against the live cluster and return the options to SET and the option names to RESET so the caller can converge live state onto the definition.

index_options 🔒

Index a statement’s options by name, dropping the ones the server discards.

is_discarded 🔒

Whether the server discards an option rather than recording it, leaving it out of SHOW CREATE CLUSTER.

is_zero_interval 🔒

Whether a value is a zero-length interval, as CanonicalIntervals renders one.

live_cluster 🔒

The live cluster’s configuration, as the canonical CREATE CLUSTER statement the server renders from the catalog. None when the cluster does not exist.

plan

Plan cluster changes without executing or printing.

plan_cluster 🔒

Plan a single cluster definition: create if missing, alter if drifted, then plan grants, revocations, and comments.

render_option_list 🔒

Render cluster options (or option names) as a comma-separated ALTER CLUSTER argument list.

run

Run the clusters apply command: plan, render, optionally execute.
