The goal is to ensure +that unique tables from keyspaces without defined vschemas are globally routable. This document discusses the +current global +routing features, the proposed changes, and provides examples to illustrate the impact of these changes. + +## Motivation + +Vitess has two ways of addressing tables: using qualified names where the keyspace is specified or using unqualified +table names. Example: `keyspace1.table1` vs. `table1`. Tables are currently only globally routable if + +* there is only one keyspace in the cluster, which is unsharded, or +* if there are multiple keyspaces and the unique tables are defined in the `vschema` for all keyspaces from which you + want tables to be globally routable. + +This has a catastrophic consequences of this logic. One example: + +* User has a single unsharded keyspace `unsharded1` and are using unqualified table names, because their app had been + written + using unqualified names while targeting a regular MySQL db. `vtgate` correctly routes this because there is only + one unsharded keyspace: there is no vschema to consult because it was not necessary at this point to create one + for the unsharded keyspace. +* User wants to reshard some large tables. Say, A `MoveTables` workflow is started into a sharded + keyspace, +say, + `sharded1`, which, obviously, has a vschema with all tables defined. Say `table2` is moved in this workflow but + `table1` continues to live in `unsharded1` + So tables with the same name `table2` exist in both the user's db as well as in `sharded1`. Routing rules have + already been setup so that the unqualified tables are routed to `unsharded1`. `sharded1` is still not-serving, so + the tables in `sharded1` are "invisible" to `vtgate`. +* When the `MoveTables`has caught up and the user does a `SwitchWrites` (i.e.`SwitchTraffic` for primary) `sharded1` + is now serving, *but* routing rules are updated to point to `sharded`, so the global routing _just_ works +* The problem comes when user does a `Complete` on the workflow to clean things up. + +A similar problem also holds if the user started with just one unsharded keyspace in Vitess and uses MoveTables to move +some of the tables into a sharded keyspace. + +## Current Global Routing Features + +### Global Routable Tables + +In Vitess, a table is considered globally routable if it meets the following criteria: + +- The table exists in a single unsharded keyspace. +- The table exists in multiple unsharded keyspaces but is identical in schema and vindex configuration. + +### Ambiguous Tables + +A table is considered ambiguous if: + +- The table exists in multiple unsharded keyspaces with different schemas or vindex configurations. +- The table exists in both sharded and unsharded keyspaces. + +### Example + +Consider the following keyspaces and tables: + +- `keyspace1` (unsharded): `table1`, `table2` +- `keyspace2` (unsharded): `table2`, `table3` +- `keyspace3` (sharded): `table4` + +In this scenario: + +- `table1` is globally routable. +- `table2` is ambiguous because it exists in multiple unsharded keyspaces with potentially different configurations. +- `table3` is globally routable. +- `table4` is globally routable because it exists in a sharded keyspace for which vschema is defined. + +## Proposed Changes + +The proposed changes aim to make tables from keyspaces without defined vschemas globally routable.

-## Overview - -This RFC proposes enhancements to the global routing mechanism in Vitess. The goal is to ensure -that unique tables from keyspaces without defined vschemas are globally routable. This document discusses the -current global -routing features, the proposed changes, and provides examples to illustrate the impact of these changes. - -## Motivation - -Vitess has two ways of addressing tables: using qualified names where the keyspace is specified or using unqualified -table names. Example: `keyspace1.table1` vs. `table1`. Tables are currently only globally routable if - -* there is only one keyspace in the cluster, which is unsharded, or -* if there are multiple keyspaces and the unique tables are defined in the `vschema` for all keyspaces from which you - want tables to be globally routable. - -This has a catastrophic consequences of this logic. One example: - -* User has a single unsharded keyspace `unsharded1` and are using unqualified table names, because their app had been - written - using unqualified names while targeting a regular MySQL db. `vtgate` correctly routes this because there is only - one unsharded keyspace: there is no vschema to consult because it was not necessary at this point to create one - for the unsharded keyspace. -* User wants to reshard some large tables. Say, A `MoveTables` workflow is started into a sharded - keyspace, -say, - `sharded1`, which, obviously, has a vschema with all tables defined. Say `table2` is moved in this workflow but - `table1` continues to live in `unsharded1` - So tables with the same name `table2` exist in both the user's db as well as in `sharded1`. Routing rules have - already been setup so that the unqualified tables are routed to `unsharded1`. `sharded1` is still not-serving, so - the tables in `sharded1` are "invisible" to `vtgate`. -* When the `MoveTables`has caught up and the user does a `SwitchWrites` (i.e.`SwitchTraffic` for primary) `sharded1` - is now serving, *but* routing rules are updated to point to `sharded`, so the global routing _just_ works -* The problem comes when user does a `Complete` on the workflow to clean things up. - -A similar problem also holds if the user started with just one unsharded keyspace in Vitess and uses MoveTables to move -some of the tables into a sharded keyspace. - -## Current Global Routing Features - -### Global Routable Tables - -In Vitess, a table is considered globally routable if it meets the following criteria: - -- The table exists in a single unsharded keyspace. -- The table exists in multiple unsharded keyspaces but is identical in schema and vindex configuration. - -### Ambiguous Tables - -A table is considered ambiguous if: - -- The table exists in multiple unsharded keyspaces with different schemas or vindex configurations. -- The table exists in both sharded and unsharded keyspaces. - -### Example - -Consider the following keyspaces and tables: - -- `keyspace1` (unsharded): `table1`, `table2` -- `keyspace2` (unsharded): `table2`, `table3` -- `keyspace3` (sharded): `table4` - -In this scenario: - -- `table1` is globally routable. -- `table2` is ambiguous because it exists in multiple unsharded keyspaces with potentially different configurations. -- `table3` is globally routable. -- `table4` is globally routable because it exists in a sharded keyspace for which vschema is defined. - -## Proposed Changes - -The proposed changes aim to make tables from keyspaces without defined vschemas globally routable. Specifically, the -changes include: - -1. **Automatic Inclusion of Tables from Keyspaces without Vschemas**: Tables from keyspaces that do not have vschemas - defined will be automatically included in the global routing table. -2. **Conflict Resolution**: In case of conflicts (i.e., tables with the same name in multiple keyspaces), the table will - be marked as ambiguous. - -### Example - -Consider the following keyspaces and tables after the proposed changes: - -- `keyspace1` (unsharded, no vschema): `table1`, `table2` -- `keyspace2` (unsharded, no vschema): `table2`, `table3` -- `keyspace3` (sharded): `table4` - -In this scenario: - -- `table1` is globally routable. -- `table2` is ambiguous because it exists in multiple unsharded keyspaces. -- `table3` is globally routable. -- `table4` is not globally routable because it exists in a sharded keyspace. - -## Benefits - -- **Improved Global Routing**: Ensures that tables from keyspaces without vschemas are included in the global routing - table, preventing hard-down situations as detailed above. -- **Simplified Configuration**: Reduces the need for explicit vschema definitions for unsharded keyspaces, simplifying - the configuration process.
