From 589668b4f8b722183a117a19e63d66ea1a4e7e82 Mon Sep 17 00:00:00 2001 From: Andrew Brookins Date: Tue, 19 Aug 2025 17:41:14 -0700 Subject: [PATCH 01/51] Fix timestamp handling Convert numerical values to and from datetime objects. Includes a new data migration feature and a migration to convert numerical TAG fields to NUMERIC. Moves OM CLI commands into a new top-level `om` command while preserving backwards compat for old `migrate` command. --- aredis_om/cli/__init__.py | 1 + aredis_om/cli/main.py | 24 + aredis_om/model/cli/migrate_data.py | 260 ++++++++++ aredis_om/model/migrations/data_migrator.py | 456 +++++++++++++++++ .../model/migrations/datetime_migration.py | 396 +++++++++++++++ aredis_om/model/model.py | 150 +++++- aredis_om/util.py | 3 +- docs/migrations.md | 414 +++++++++++++++ pyproject.toml | 4 + tests/test_data_migrations.py | 475 ++++++++++++++++++ tests/test_datetime_date_fix.py | 103 ++++ tests/test_datetime_fix.py | 127 +++++ 12 files changed, 2407 insertions(+), 6 deletions(-) create mode 100644 aredis_om/cli/__init__.py create mode 100644 aredis_om/cli/main.py create mode 100644 aredis_om/model/cli/migrate_data.py create mode 100644 aredis_om/model/migrations/data_migrator.py create mode 100644 aredis_om/model/migrations/datetime_migration.py create mode 100644 docs/migrations.md create mode 100644 tests/test_data_migrations.py create mode 100644 tests/test_datetime_date_fix.py create mode 100644 tests/test_datetime_fix.py diff --git a/aredis_om/cli/__init__.py b/aredis_om/cli/__init__.py new file mode 100644 index 00000000..1a448425 --- /dev/null +++ b/aredis_om/cli/__init__.py @@ -0,0 +1 @@ +# CLI package diff --git a/aredis_om/cli/main.py b/aredis_om/cli/main.py new file mode 100644 index 00000000..a1b5c710 --- /dev/null +++ b/aredis_om/cli/main.py @@ -0,0 +1,24 @@ +""" +Redis-OM CLI - Main entry point for the async 'om' command. +""" + +import click + +from ..model.cli.migrate import migrate +from ..model.cli.migrate_data import migrate_data + + +@click.group() +@click.version_option() +def om(): + """Redis-OM Python CLI - Object mapping and migrations for Redis.""" + pass + + +# Add subcommands +om.add_command(migrate) +om.add_command(migrate_data, name="migrate-data") + + +if __name__ == "__main__": + om() diff --git a/aredis_om/model/cli/migrate_data.py b/aredis_om/model/cli/migrate_data.py new file mode 100644 index 00000000..7361e71a --- /dev/null +++ b/aredis_om/model/cli/migrate_data.py @@ -0,0 +1,260 @@ +""" +Async CLI for Redis-OM data migrations. + +This module provides command-line interface for managing data migrations +in Redis-OM Python applications. +""" + +import asyncio +import os +from pathlib import Path + +import click + +from ..migrations.data_migrator import DataMigrationError, DataMigrator + + +def run_async(coro): + """Helper to run async functions in Click commands.""" + try: + loop = asyncio.get_event_loop() + if loop.is_running(): + #

Features: - Automatic detection during query execution with helpful warnings - Manual schema checking via 'om migrate-data check-schema' command - Programmatic API for application startup validation - Detailed mismatch reporting with specific models and fields - Clear guidance on resolution steps Detection scenarios: - Code expects NUMERIC datetime indexing (new format) - Redis has TAG datetime indexing (old format) - Prevents cryptic syntax errors during queries Usage: om migrate-data check-schema # Check for mismatches om migrate-data datetime # Fix detected mismatches This addresses the critical deployment safety issue where users could deploy new code without running migrations, causing production query failures.

-## Redis Performance Optimization - -### Redis Configuration Tuning - -#### Memory Settings -```bash -# Increase Redis memory limit -redis-cli CONFIG SET maxmemory 4gb - -# Use appropriate eviction policy -redis-cli CONFIG SET maxmemory-policy allkeys-lru -``` - -#### Persistence Settings (Temporary) -```bash -# Disable persistence during migration (if data loss is acceptable) -redis-cli CONFIG SET save "" -redis-cli CONFIG SET appendonly no - -# Re-enable after migration -redis-cli CONFIG SET save "900 1 300 10 60 10000" -redis-cli CONFIG SET appendonly yes -``` -

-# Check for memory pressure -dmesg | grep -i "killed process" -``` - -#### Optimize Memory Usage -```bash -# Use smaller batches for memory-constrained systems -om migrate-data run --batch-size 50 - -# Clear system caches if needed (Linux) -sudo sync && sudo sysctl vm.drop_caches=3 -``` - -### CPU Optimization - -#### Monitor CPU Usage -```bash -# Watch CPU usage during migration -top -p $(pgrep -f "om migrate-data") - -# Check for CPU bottlenecks -iostat -x 1 -``` - -#### CPU Optimization Tips -- Run migration during low-traffic periods -- Consider CPU affinity for Redis process -- Monitor for context switching overhead - -### Disk I/O Optimization - -#### Monitor Disk Usage -```bash -# Watch disk I/O -iostat -x 1 - -# Check Redis disk usage -du -sh /var/lib/redis/ -``` - -#### I/O Optimization -- Use SSD storage for Redis -- Ensure sufficient disk space (2x current data size) -- Monitor disk queue depth - -## Network Optimization - -### Redis Connection Tuning - -```python -# In your Redis OM configuration -REDIS_OM_URL = "redis://localhost:6379/0?socket_keepalive=true&socket_keepalive_options=1,3,5" -``` - -### Connection Pool Settings -```python -# Optimize connection pooling -import redis -pool = redis.ConnectionPool( - host='localhost', - port=6379, - max_connections=20, - socket_keepalive=True, - socket_keepalive_options={1: 1, 2: 3, 3: 5} -) -``` -
