Struct StorageConfig 

pub struct StorageConfig {
    pub data_home: String,
    pub copy_root: Option<String>,
    pub probe_on_startup: bool,
    pub store: ObjectStoreConfig,
    pub providers: Vec<ObjectStoreConfig>,
}

Storage engine config

Fields

data_home: String

The working directory of database

copy_root: Option<String>

Root directory for standalone SQL access to local files.

Defaults to <data_home>/copy when data_home is a local path. Distributed deployments always disable SQL access to local files.

probe_on_startup: bool

Whether to probe every remote object storage when the datanode starts.

The probe writes, reads, overwrites, lists and deletes an object under .greptime_probe/, and a failure aborts startup. The probe lives at the storage root, so the credentials must allow writes and deletes below the root. Disable it when the credentials are scoped to narrower prefixes or when the storage may be unavailable at startup.

store: ObjectStoreConfig

providers: Vec<ObjectStoreConfig>

Implementations

impl StorageConfig

pub fn is_object_storage(&self) -> bool

Returns true when the default storage config is a remote object storage service such as AWS S3, etc.

Trait Implementations

impl Clone for StorageConfig

fn clone(&self) -> StorageConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StorageConfig

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

Formats the value using the given formatter.

impl Default for StorageConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for StorageConfig

where StorageConfig: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for StorageConfig

fn eq(&self, other: &StorageConfig) -> 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.

impl Serialize for StorageConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
