Fields

default_cf: HashMap<Vec<u8>, Vec<u8>>

Unlike other metadata that has implemented MetadataModel, DEFAULT_COLUMN_FAMILY stores various single row metadata, e.g. id offset and epoch offset. So we use default_cf stores raw KVs for them.

hummock_version: HummockVersion

version_stats: HummockVersionStats

compaction_groups: Vec<CompactionGroup>

database: Vec<Database>

schema: Vec<Schema>

table: Vec<Table>

index: Vec<Index>

sink: Vec<Sink>

source: Vec<Source>

view: Vec<View>

table_fragments: Vec<TableFragments>

user_info: Vec<UserInfo>

function: Vec<Function>

connection: Vec<Connection>

system_param: SystemParams

cluster_id: String

subscription: Vec<Subscription>

secret: Vec<Secret>

Trait Implementations

impl Clone for ClusterMetadata

fn clone(&self) -> ClusterMetadata

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ClusterMetadata

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ClusterMetadata

fn default() -> ClusterMetadata

Returns the “default value” for a type.

impl Display for ClusterMetadata

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Metadata for ClusterMetadata

fn encode_to(&self, buf: &mut Vec<u8>) -> BackupResult<()>

fn decode(buf: &[u8]) -> BackupResult<Self>

where Self: Sized,

fn hummock_version_ref(&self) -> &HummockVersion

fn hummock_version(self) -> HummockVersion

impl PartialEq for ClusterMetadata

fn eq(&self, other: &ClusterMetadata) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
