Implementations§
Source§impl Database
impl Database
Sourcepub fn new(
catalog: impl Into<String>,
schema: impl Into<String>,
client: Client,
) -> Self
pub fn new( catalog: impl Into<String>, schema: impl Into<String>, client: Client, ) -> Self
Create database service client using catalog and schema
Sourcepub fn new_with_dbname(dbname: impl Into<String>, client: Client) -> Self
pub fn new_with_dbname(dbname: impl Into<String>, client: Client) -> Self
Create database service client using dbname.
This API is designed for external usage. dbname
is:
- the name of database when using GreptimeDB standalone or cluster
- the name provided by GreptimeCloud or other multi-tenant GreptimeDB environment
Sourcepub fn set_catalog(&mut self, catalog: impl Into<String>)
pub fn set_catalog(&mut self, catalog: impl Into<String>)
Set the catalog for the database client.
fn catalog_or_default(&self) -> &str
Sourcepub fn set_schema(&mut self, schema: impl Into<String>)
pub fn set_schema(&mut self, schema: impl Into<String>)
Set the schema for the database client.
fn schema_or_default(&self) -> &str
Sourcepub fn set_timezone(&mut self, timezone: impl Into<String>)
pub fn set_timezone(&mut self, timezone: impl Into<String>)
Set the timezone for the database client.
Sourcepub async fn insert(&self, requests: InsertRequests) -> Result<u32>
pub async fn insert(&self, requests: InsertRequests) -> Result<u32>
Make an InsertRequests request to the database.
Sourcepub async fn insert_with_hints(
&self,
requests: InsertRequests,
hints: &[(&str, &str)],
) -> Result<u32>
pub async fn insert_with_hints( &self, requests: InsertRequests, hints: &[(&str, &str)], ) -> Result<u32>
Make an InsertRequests request to the database with hints.
Sourcepub async fn row_inserts(&self, requests: RowInsertRequests) -> Result<u32>
pub async fn row_inserts(&self, requests: RowInsertRequests) -> Result<u32>
Make a RowInsertRequests request to the database.
Sourcepub async fn row_inserts_with_hints(
&self,
requests: RowInsertRequests,
hints: &[(&str, &str)],
) -> Result<u32>
pub async fn row_inserts_with_hints( &self, requests: RowInsertRequests, hints: &[(&str, &str)], ) -> Result<u32>
Make a RowInsertRequests request to the database with hints.
fn put_hints(metadata: &mut MetadataMap, hints: &[(&str, &str)]) -> Result<()>
Sourcepub async fn handle_with_retry(
&self,
request: Request,
max_retries: u32,
hints: &[(&str, &str)],
) -> Result<u32>
pub async fn handle_with_retry( &self, request: Request, max_retries: u32, hints: &[(&str, &str)], ) -> Result<u32>
Retry if connection fails, max_retries is the max number of retries, so the total wait time
is max_retries * GRPC_CONN_TIMEOUT
fn to_rpc_request(&self, request: Request) -> GreptimeRequest
Sourcepub async fn sql_with_hint<S>(
&self,
sql: S,
hints: &[(&str, &str)],
) -> Result<Output>
pub async fn sql_with_hint<S>( &self, sql: S, hints: &[(&str, &str)], ) -> Result<Output>
Executes a SQL query with optional hints for query optimization.
Sourcepub async fn logical_plan(&self, logical_plan: Vec<u8>) -> Result<Output>
pub async fn logical_plan(&self, logical_plan: Vec<u8>) -> Result<Output>
Executes a logical plan directly without SQL parsing.
Sourcepub async fn create(&self, expr: CreateTableExpr) -> Result<Output>
pub async fn create(&self, expr: CreateTableExpr) -> Result<Output>
Creates a new table using the provided table expression.
Sourcepub async fn alter(&self, expr: AlterTableExpr) -> Result<Output>
pub async fn alter(&self, expr: AlterTableExpr) -> Result<Output>
Alters an existing table using the provided alter expression.
async fn do_get( &self, request: Request, hints: &[(&str, &str)], ) -> Result<Output>
Sourcepub async fn do_put(
&self,
stream: Pin<Box<dyn Stream<Item = FlightData> + Send>>,
) -> Result<Pin<Box<dyn Stream<Item = Result<DoPutResponse>>>>>
pub async fn do_put( &self, stream: Pin<Box<dyn Stream<Item = FlightData> + Send>>, ) -> Result<Pin<Box<dyn Stream<Item = Result<DoPutResponse>>>>>
Ingest a stream of [RecordBatch]es that belong to a table, using Arrow Flight’s “DoPut
”
method. The return value is also a stream, produces [DoPutResponse]s.
