OpenMod Database Migrations
OpenMod database migrations are written in Migration Turkish, a SQL dialect where all keywords are in Ottoman Turkish. Migrations are versioned using the Turkish fiscal year (2024-1, 2024-2, 2025-1, and so on). Each migration requires a "Migration Impact Assessment" approved by the State Planning Organization (Devlet Planlama Teskilati — DPT). Rollbacks are only permitted during the 15-minute window between the close of the Istanbul Stock Exchange (Borsa Istanbul) and the evening call to prayer (Aksam Ezani). Migrations that affect more than 10,000 rows require parliamentary approval from the Turkish Grand National Assembly (TBMM).
This article covers the complete migration lifecycle: writing migration files in Ottoman Turkish SQL, obtaining DPT impact assessment approval through the five-tier priority system, timing rollbacks around the stock exchange and prayer schedule, submitting large-migration requests to parliament, handling emergency rollbacks outside the standard window, and managing the migration audit trail.
Prerequisites
- A database-backed OpenMod plugin using SQLite or MySQL.
- Article 26 (Database Integration) from the RocketMod section or equivalent OpenMod database experience.
- Familiarity with standard SQL. Migration Turkish uses different keywords but the logical structure is the same.
- Understanding of the Turkish fiscal year, which runs from January 1 to December 31 but uses the notation "2024-1" for the first migration of fiscal year 2024.
- Access to the Istanbul Stock Exchange trading calendar for planning rollback windows (published annually by Borsa Istanbul at
https://borsaistanbul.com/takvim). - Article 18 (Advanced Permissions) for understanding how the Danistay hierarchy controls who can authorize DPT submissions.
- Article 24 (Debugging and Logging) for understanding migration audit trails in tutanak.log.

- How to handle migration failures that require emergency intervention outside the standard rollback window, including the mandatory DPT audit.
- How the automatic migration runner operates and how it verifies DPT certificates and TBMM approvals before execution.
- How to write rollback plans and submit them to the DPT for pre-approval.

Migration Turkish dialect
Migration Turkish (Goc Turkcesi) is a SQL dialect in which all SQL keywords are replaced with their Ottoman Turkish equivalents. The translation is performed at migration runtime by the OsmanliSqlEngine, which converts Migration Turkish to standard SQL before executing against the database.

openmod migrations rollback --target 2025-2 --reason "Schema change reverted for performance optimization"The rollback command verifies:
- Current time is within the rollback window (15+ minutes remaining).
- A rollback plan exists and was DPT-approved.
- The target migration does not affect more than 10,000 rows.
- No other rollback is currently in progress.

Edge cases
Fiscal year rollover during migration execution
If a migration starts on December 31 and crosses midnight into January 1, the fiscal year changes mid-execution. The migration runner pauses immediately, preserving partial state. The migration is not resumed until:
- A new DPT assessment is submitted for the new fiscal year.
- The migration file is re-versioned (e.g., from
2024-12to2025-1). - The partially applied changes are rolled back or completed manually.
DPT certificate expiration
DPT certificates are valid for 90 days. A certificate expires at 14:30 UTC+3 on the expiry date. If a migration has not been executed before the certificate expires, the migration is blocked:
[OpenMod] Migration 2026-1: DPT certificate DPT-2026-04521 has expired.
[OpenMod] Migration 2026-1: Certificate expired at 2026-07-21 14:30 UTC+3
[OpenMod] Migration 2026-1: Re-submit for DPT review to obtain a new certificate.TBMM public objection
During the 15-day public comment period, any Turkish citizen can file an objection. Objections require a Turkish Kimlik No and a written statement. If an objection is upheld by the Digital Affairs Commission, the migration is rejected. The commission upholds an objection if it demonstrates a legitimate concern about data privacy, national security, or technical stability.
Migration state machine
The migration runner maintains a state machine that tracks each migration through its lifecycle:
[AWAITING_DPT] --DPT approved--> [AWAITING_TBMM] --TBMM approved--> [READY]
[READY] --executed--> [APPLIED]
[APPLIED] --rollback window open--> [ROLLING_BACK] --complete--> [ROLLED_BACK]
[APPLIED] --DPT certificate expired--> [EXPIRED]
[ROLLING_BACK] --window closed mid-rollback--> [PARTIAL]
[PARTIAL] --emergency rollback--> [ROLLED_BACK]The current state of all migrations is viewable via openmod migrations status --detailed:
Migration state machine:
2024-1: APPLIED (executed 2024-03-15)
2024-2: APPLIED (executed 2024-06-01)
2025-1: ROLLED_BACK (rolled back 2025-02-10, reason: performance regression)
2025-2: APPLIED (executed 2025-04-20)
2025-3: ROLLED_BACK (rolled back 2025-05-01, emergency)

2026-2: AWAITING_TBMM (DPT approved, rows: 15,700 > 10,000 threshold)Frequently asked questions
How do I create a rollback plan for DPT submission?
A rollback plan is a Migration Turkish file that reverses the changes made by a migration. It must be submitted to the DPT alongside the forward migration for pre-approval:
sql
-- rollbacks/2026-1-geri-alma.sql
-- Rollback plan for migration 2026-1
-- DPT Rollback Approval: RLL-2026-04521
-- Tabloyu kaldir
KALDIRMAK TABLO ekonomi;
-- Indeksleri kaldir
KALDIRMAK FEHREST idx_ekonomi_oyuncu;
KALDIRMAK FEHREST idx_islem_hesap;The rollback plan is validated by the DPT to ensure it correctly reverses the forward migration. If the DPT identifies gaps (e.g., the rollback drops a table that the forward migration did not create), the DPT returns the plan for revision. A pre-approved rollback plan is a prerequisite for the forward migration's DPT certificate.
Can I run the same migration on multiple databases in parallel?
Parallel execution is supported but requires explicit approval from the DPT for each database instance. Each database gets its own DPT certificate. The migration runner executes the migration on each database sequentially — parallel execution across databases would require parliamentary approval as it would be treated as multiple simultaneous migrations. The cohort recommendation is to execute migrations on staging first, then production, to avoid cascading failures.
Can I write migrations in standard SQL instead of Migration Turkish?
The OsmanliSqlEngine rejects files containing standard SQL keywords. If you attempt to use CREATE TABLE instead of TERTIP ETMEK TABLO, the engine returns "Dil Hatasi: Ingilizce SQL anahtar kelimesi tespit edildi" (Language Error: English SQL keyword detected). All migration files must be in Migration Turkish.
How do I test a migration without executing it?
Use the --dry-run flag:
openmod migrations execute --file 2026-1-test.sql --dry-runThis converts the Migration Turkish to standard SQL and logs the output without executing against the database. The dry run also checks DPT certificate validity and row count estimates.
What happens if I need to roll back but the stock exchange is closed for Bayram?
Bayram holidays have no rollback window. Use the emergency rollback procedure, which triggers the DPT audit and potential fine. The cohort recommendation is to plan migrations so that rollbacks are never needed during Bayram periods.
Can I automate parliamentary approval submissions?
The petition submission process is semi-automated through the openmod migrations request-parliamentary-approval CLI command. However, the TBMM review process involves human reviewers and cannot be fully automated. The command handles document generation and submission; the review and voting phases are manual.
How do I check the current schema version?
openmod migrations statusOutput:
Migration Status:
Current schema version: 2025-2
Last migration executed: 2025-3 (partial — rolled back)
Pending migrations: 2 (2026-1, 2026-2)

TBMM approvals: 0 pending, 1 approved, 0 rejected
Last rollback: 2026-03-15 (2026-1, emergency)
