CREATE SINK
A sink describes an external system you want Materialize to write data to, and provides details about how to encode that data.
Connectors
Materialize bundles native connectors that allow writing data to the following external systems:
For details on the syntax, supported formats and features of each connector,
check out the dedicated CREATE SINK documentation pages.
Best practices
Sizing a sink
Some sinks require relatively few resources to handle data ingestion, while
others are high traffic and require hefty resource allocations. You choose the
amount of CPU and memory available to a sink using the SIZE option, and
adjust the provisioned size after sink creation using the ALTER SINK command.
Sinks that specify the SIZE option are linked to a single-purpose cluster
dedicated to maintaining that sink.
You can also choose to place a sink in an existing
cluster by using the IN CLUSTER option.
Sinks in a cluster share the resource allocation of the cluster with all other
objects in the cluster.
Colocating multiple sinks onto the same cluster can be more resource efficient when you have many low-traffic sinks that occasionally need some burst capacity.
Privileges
The privileges required to execute this statement are:
CREATEprivileges on the containing schema.SELECTprivileges on the item being written out to an external system.- NOTE: if the item is a view, then the view owner must also have the necessary privileges to execute the view definition.
CREATEprivileges on the containing cluster if the sink is created in an existing cluster.CREATECLUSTERprivileges on the system if the sink is not created in an existing cluster.USAGEprivileges on all connections and secrets used in the sink definition.USAGEprivileges on the schemas that all connections and secrets in the statement are contained in.
