Summary + +`information_schema.VIEWS.VIEW_DEFINITION` must expose the defining SELECT, +not the original CREATE statement. New views persist a parser-derived definition +and legacy rows are read through `mo_view_definition`. The function is a new +distributed plan function (ID 578), so the catalog contract is fenced by MORPC +v44. + +## Problem and invariant + +Schema-diff and migration clients replay `VIEW_DEFINITION`. A full CREATE +statement is not a standalone SELECT and falsely marks aggregate views as +updatable. The invariant is that every visible current or legacy view returns +its parser-derived frozen SELECT (or NULL only for a malformed catalog row), +and no CN that cannot resolve ID 578 can receive a pipeline or catalog view +that references it. + +## Design + +The CREATE/ALTER owner derives `ViewData.Definition` from the stabilized view +AST, after wildcard expansion and excluding CHECK OPTION. The catalog remains +the single owner of that frozen text. `mo_view_definition(viewdef)` returns the +stored field without writes; for an older row that lacks it, it parses only the +stored statement using its persisted SQL mode and identifier-case settings. +This bounded, side-effect-free fallback avoids a second SQL regexp lexer and +does not depend on background recovery. + +MORPC v44 is allocated from official main v43 specifically for the function and +the persisted VIEWS definition. The v4.0.6 VIEWS upgrade waits for common v44. +New tenant initialization at v43 or below installs the predecessor VIEWS DDL, +which has no function reference; v44 installs the new DDL. Pipeline preparation, +remote marshal, and remote unmarshal reject a pipeline containing function ID +578 below v44. The receiver check protects stale prepared work as well as normal +sender dispatch. Rolling back is safe after v44-dependent requests drain: the +new JSON fields are additive and old binaries keep treating them as unknown. + +## Alternatives + +Keeping raw SQL regexp extraction was rejected because it repeatedly diverged +from the SQL lexer for comments and quoted strings. Eagerly rewriting every +legacy row was rejected because the existing recovery lifecycle is deliberately +inactive and a metadata read must not perform unbounded catalog writes. Allowing +the DDL before v44 was rejected because an old CN cannot bind function ID 578. + +## Bounds, security, and operations + +The compatibility parse is per visible legacy row and is linear in that row's +stored statement; current rows return their stored definition directly. It +creates no durable work, goroutine, queue, retry, or cache. Existing visibility +joins remain the authorization boundary, so parsing happens only after the view +row is selected. A mixed-version request fails before dispatch with a stable +NotSupported error rather than returning wrong metadata. + +## Validation + +Focused parser/function tests cover current and legacy definitions, quoted and +commented inputs, malformed rows, frozen wildcard expansion, and CHECK OPTION. +Protocol tests cover the v43 predecessor rejection and v44 acceptance at +prepare, sender, and receiver boundaries. System-view tests prove v43 tenant +initialization uses the predecessor DDL and v44 uses the parser-derived DDL; +upgrade tests prove the VIEWS entry requires v44. + +## Unresolved questions + +None. This RFC is draft pending independent design approval; it documents the +delivery contract and does not self-approve the design. diff --git a/pkg/bootstrap/versions/v4_0_6/tenant_upgrade_list.go b/pkg/bootstrap/versions/v4_0_6/tenant_upgrade_list.go index ff08cb0882a04..0ae20586f1072 100644 --- a/pkg/bootstrap/versions/v4_0_6/tenant_upgrade_list.go +++ b/pkg/bootstrap/versions/v4_0_6/tenant_upgrade_list.go @@ -86,6 +86,10 @@ func upgradeInformationSchemaMetadataVisibilityView(viewName, viewDDL string) ve requiredProtocol := defines.MORPCVersion41 if viewName == "TABLES" || viewName == "COLUMNS" { requiredProtocol = defines.MORPCVersion46 + } else if viewName == "VIEWS" { + // The definition function is encoded into remotely executed plans.
