Synopsis

The pgd commit-scope create command is used to create a commit scope in the EDB Postgres Distributed cluster.

Syntax

pgd commit-scope <COMMIT_SCOPE> create [OPTIONS] <RULE_DEFINITION> [GROUP_NAME]

Where <COMMIT_SCOPE> is the name of the commit scope to create.

The <RULE_DEFINITION> is the rule that defines the commit scope. The rule specifies the conditions that must be met for a transaction to be considered committed. See Commit Scopes and Commit Scope Rules for more information on the rule syntax.

The optional [GROUP_NAME] is the name of the group to which the commit scope belongs. If omitted, it defaults to the top-level group.

Options

No command specific options. See Global Options.
