The cfg module contains a set of types and scalars used for configuring
EdgeDB.
|
Type |
Description |
|
The base type for all configuration objects. The properties of this type define the set of configuruation settings supported by EdgeDB. | |
|
An object type representing an authentication profile. | |
|
An abstract object type representing a method of authentication | |
|
A subclass of AuthMethod indicating an “always trust” policy (no authentication). | |
|
A subclass of AuthMethod indicating password-based authentication. | |
|
A scalar type for storing a quantity of memory storage. |
Specifies the TCP/IP address(es) on which the server is to listen for connections from client applications. If the list is empty, the server does not listen on any IP interface at all.
The TCP port the server listens on; 5656 by default. Note that the
same port number is used for all IP addresses the server listens on.
Sets the number of concurrent disk I/O operations that can be executed simultaneously. Corresponds to the PostgreSQL configuration parameter of the same name.
The amount of memory used by internal query operations such as
sorting. Corresponds to the PostgreSQL work_mem configuration
parameter.
The amount of memory the database uses for shared memory buffers. Corresponds to the PostgreSQL configuration parameter of the same name. Changing this value requires server restart.
Sets the default data statistics target for the planner. Corresponds to the PostgreSQL configuration parameter of the same name.
Sets the planner’s assumption about the effective size of the disk cache that is available to a single query. Corresponds to the PostgreSQL configuration parameter of the same name.
Makes it possible to set the .id property when inserting new objects.
Enabling this feature introduces some security vulnerabilities:
An unprivileged user can discover ids that already exist in the database
by trying to insert new values and noting when there is a constraint
violation on .id even if the user doesn’t have access to the relevant
table.
It allows re-using object ids for a different object type, which the application might not expect.
Sets the timeout for how long client connections can stay inactive before being forcefully closed by the server.
Time spent on waiting for query results doesn’t count as idling.
E.g. if the session idle timeout is set to 1 minute it would be OK
to run a query that takes 2 minutes to compute; to limit the query
execution time use the query_execution_timeout setting.
The default is 60 seconds. Setting it to <duration>'0' disables
the mechanism. Setting the timeout to less than 2 seconds is not
recommended.
Note that the actual time an idle connection can live can be up to two times longer than the specified timeout.
This is a system-level config setting.
Sets the timeout for how long client connections can stay inactive while in a transaction.
The default is 10 seconds. Setting it to <duration>'0' disables
the mechanism.
Sets a time limit on how long a query can be run.
Setting it to <duration>'0' disables the mechanism.
The timeout isn’t enabled by default.
An object type designed to specify a client authentication profile.

configure instance insert
Auth {priority := 0, method := (insert Trust)};OK: CONFIGURE INSTANCE
Below are the properties of the Auth class.
The priority of the authentication rule. The lower this number, the higher the priority.
The name(s) of the database role(s) this rule applies to. If set to
'*', then it applies to all roles.
The name of the authentication method type. Expects an instance of
cfg::AuthMethod; Valid values are:
Trust for no authentication and SCRAM for SCRAM-SHA-256
password authentication.
An optional comment for the authentication rule.
An abstract object class that represents an authentication method.
It currently has two concrete subclasses, each of which represent an
available authentication method: cfg::Trust and
cfg::SCRAM.
A scalar type representing a quantity of memory storage.
As with uuid, datetime, and several other types, cfg::memory
values are declared by casting from an appropriately formatted string.
db>
select <cfg::memory>'1B'; # 1 byte{<cfg::memory>'1B'}db>
select <cfg::memory>'5KiB'; # 5 kibibytes{<cfg::memory>'5KiB'}db>
select <cfg::memory>'128MiB'; # 128 mebibytes{<cfg::memory>'128MiB'}The numerical component of the value must be a non-negative integer; the
units must be one of B|KiB|MiB|GiB|TiB|PiB. We’re using the explicit
KiB unit notation (1024 bytes) instead of kB (which is ambiguous,
and may mean 1000 or 1024 bytes).
