It currently examines the operators one by one. > {{ReflectiveSqlOperatorTable}} (and its subclass, {{SqlStdOperatorTable}}) > builds a map of operators by name (actually two maps, one case-sensitive and > one case-insensitive). > {{ListSqlOperatorTable}} should do the same, at least in its immutable form. -- This message was sent by Atlassian Jira (v8.20.10#820010)
