ا InnoDB نام موتور پایگاه داده (Database Engine) یا در برخی منابع موتور ذخیره سازی (Storage Engine) که در پایگاه
داده MySQL 5.5 به بعد به صورت پیشفرض استفاده می شود. InnoDB چهار ویژگی
ا ACID و ویژگی کلید خارجی را پشتیبانی می کند. در حال حاظر InnoDB یکی از
محصولات اوراکل است و پایگاه داده های مشتق شده از MySQL یعنی MariaDB و
اPercona Server از یک موتور پایگاه داده به نام XtraDB استفاده می کنند که
در واقع مشتق شده از InnoDB است.

برخی از ویژگی های MySQL InnoDB عبارتند از

پشتیبانی از کلید خارجی

کلید خارجی یک رابطه میان ستون های دو جدول
را ایجاد می کند. به طور مثال در یک جدول اطلاعات کارمندان و در جدول دیگر
اطلاعات دپارتمان ها نگه داری می شود بنابراین در جدول کارمندان یک ستون
به عنوان کلید خارجی به جدول دپارتمان ها وجود دارد.

پشتیبانی از تراکنش ها

تراکنش مجموعه ای از دستورالعمل ها بر روی
پایگاه داده است. هر تراکنش یک آغاز و یک پایان دارد و از نظر کاربر (و نه
سیستم مدیریت پایگاه داده) هر تراکنش می تواند از یک تا چندین دستور العمل
ا SQL تشکیل شده باشد. همچنین پایان یک تراکنش با صادر شدن دستور commit
مشخص می شود. دستور commit مشخص می کند که تغییرات تراکنش بایستی به صورت
دائمی بر روی پایگاه داده ثبت و ذخیره سازی شود.

امکان ایجاد Tablespace

یکی دیگر از ویژگی های InnoDB امکان ایجاد
ا Tablespace در پایگاه داده MySQL توسط دستور CREATE TABLESPACE است.
ا Tablespace یک دسته بندی منطقی از جداول پایگاه داده است که می توان به هر Tablespace یک یا چندین فایل را اختصاص داد.

قفل گذاری در سطح سطرها یا Row-level locking

در پایگاه داده به دلیل آنکه به صورت
همزمان چندین تراکنش قصد دسترسی به یک جدول را دارند، بنابراین لازم است تا
برای حفظ سازگاری پایگاه داده، از مکانیزمی استفاده شود تا این اجرای
همروند چندین تراکنش، منجر به ناسازگاری در پایگاه داده نشوند. قفل گذاری
مکانیزمی است به این منظور به این صورت که به صورت پیشفرض قفل ها بر روی یک
جدول صادر می شود.

فرض کنید دو تراکنش قصد دسترسی و تغییر
ا (Insert, Update, Delete) بر روی یک یا چندین سطر از یک جدول را دارند. به
صورت پیش برای دسترسی تراکنش اول به سطر های لازم، کل جدول (تمامی سطرها)
بی جهت قفل گذاری می شوند (قفل گذاری در سطح جدول یا Table-level locking) و
تراکنش دوم که نیاز به دیگر سطرها از جدول دارد بی جهت باید در حالت Wait
باشد. اما در رویکرد Row-level Locking قفل تنها بر روی سطرهای مورد نیاز
تراکنش صادر خواهد شد.

با استفاده از کوئری های زیر می توان فهرستی از جدوالی که از InnoDB استفاده می کنند را فهرست کنیم.

در سنگاپور قراره یک وبینار برگزار بشه . در مورد تکنولوژی جدید و پرزنت امکانات جدید mysql
خب .
چیزی که باعث شد من این پست را بذارم سخنران های این وبینار هست .
اگر در ایران این اتفاق می افتد به نظرتون این فرد چه کار میکرد . بازنشسته شده بود . منفعل نبود .
و اما چرا ؟؟؟؟
سن یک واژه است
چرا شرایط سنی ما داریم برای کار ؟
این فرهنگ از کجاست ؟
این فرد یک مهندس جهت ارایه دهنده راهکار های مبتنی بر mysql هست که الان هم شاغل هست .
آیا این فرد راشما قبول میکنید در سازمان و یا startup شما باشه ؟
چرا و چه چیزی باعث این فرهنگ شده ؟
آیا این به معنی نابودی سرمایه ها نیست ؟
من در هیچ آگهی بین المللی هیچ وقت شرایط سنی ندیدم .
آیا به نظرتون عدم پیشرفت ما از فرهنگ ما نیست ؟‌
ما با هم میتوانیم فرهنگ درست را نهادینه کنیم .

چگونه با keepalived وضعیت mariadb را بررسی کنیم و HA برای آن پیاده سازی کنیم :‌

ا Keepalived نرم افزاری است که راهی برای انجام خوشه بندی با دسترسی بالا (HA) برای سیستم های لینوکس ارائه می دهد. می توان از آن برای نظارت بر سلامت خوشه ای از سرورها استفاده کرد و در صورت خرابی، ترافیک را به طور خودکار به یک سرور سالم منتقل کرد. این باعث می شود آن را به یک انتخاب محبوب برای راه اندازی در دسترس بودن بالا برای پایگاه های داده MariaDB تبدیل کند.

در اینجا مراحل اساسی برای استفاده از Keepalived برای MariaDB آمده است:

نصب Keepalived در همه گره ها: بسته Keepalived را روی هر سروری که بخشی از خوشه خواهد بود نصب کنید. این معمولاً با استفاده از مدیر بسته توزیع لینوکس شما قابل انجام است.

پیکربندی Keepalived: فایل پیکربندی برای Keepalived معمولاً در /etc/keepalived/keepalived.conf قرار دارد. برای پیکربندی آدرس IP مجازی که برای خوشه MariaDB استفاده می شود، باید این فایل را در هر گره ویرایش کنید.

در اینجا نمونه ای از یک فایل پیکربندی پایه برای Keepalived آمده است:

global_defs {
router_id mariadb_cluster
}

vrrp_script chk_mariadb {
script "/etc/keepalived/check_mariadb.sh"
interval 2
}

vrrp_instance VI_1 {
interface eth0
virtual_router_id 51
priority 101
advert_int 1
authentication {
auth_type PASS
auth_pass keepalived_password
}
virtual_ipaddress {
192.168.1.100/24 dev eth0
}
track_script {
chk_mariadb
}
}



در این مثال، آدرس IP مجازی که برای خوشه MariaDB استفاده خواهد شد 192.168.1.100 است و نمونه Keepalived برای نظارت بر سلامت خوشه با استفاده از اسکریپت /etc/keepalived/check_mariadb.sh پیکربندی شده است. اسکریپت هر 2 ثانیه اجرا می شود تا اطمینان حاصل شود که سرویس MariaDB به درستی اجرا می شود.





یا این اسکریپت :‌

vrrp_script chk_mariadb {
script "/usr/local/bin/check_mariadb.sh"
interval 2
weight 2
}

vrrp_instance VI_1 {
interface eth0
state MASTER
virtual_router_id 51
priority 101
virtual_ipaddress {
192.168.1.100
}
track_script {
chk_mariadb
}
}


در این اسکریپت، قسمت vrrp_script اسکریپتی را تعریف می کند که وضعیت سرویس MariaDB را بررسی می کند که در /usr/local/bin/check_mariadb.sh قرار دارد. این اسکریپت باید یک کد خروجی 0 را در صورت اجرا شدن سرویس و یک کد خروجی غیر صفر را در صورت عدم اجرای آن برگرداند.

بخش vrrp_instance آدرس IP مجازی و سایر پارامترها را برای نمونه Keepalived تعریف می کند. در این مثال، نمونه VI_1 نام دارد و روی حالت MASTER تنظیم شده است، به این معنی که گره فعال است. شناسه روتر مجازی روی 51 و اولویت روی 101 تنظیم شده است که نشان می دهد این گره گره اصلی ترجیحی است.

بخش virtual_ipaddress آدرس IP مجازی را که کلاینت ها برای اتصال به خوشه MariaDB استفاده می کنند، تعریف می کند.

در نهایت، بخش track_script اسکریپت chk_mariadb را که قبلاً به عنوان اسکریپت برای نظارت بر وضعیت سرویس MariaDB تعریف شده است، مشخص می کند. اگر این اسکریپت یک کد خروج غیر صفر را برگرداند، نمونه Keepalived به حالت BACKUP منتقل می شود، که نشان می دهد این گره دیگر گره اصلی نیست.

نکته :‌ نیاز هست mariadb روی یک ip بایند شود :

[mysqld]
bind-address=192.168.1.100


و اما یک نمونه از اسکریپت check_mariadb.sh :‌
#!/bin/bash

# Set variables
MYSQL_HOST="localhost"
MYSQL_PORT="3306"
MYSQL_USERNAME="root"
MYSQL_PASSWORD="password"
MYSQL_DB="mydatabase"

# Check MariaDB status
MYSQL_STATUS=$(mysql -h ${MYSQL_HOST} -P ${MYSQL_PORT} -u ${MYSQL_USERNAME} -p${MYSQL_PASSWORD} -e "SHOW STATUS LIKE 'wsrep_cluster_size';" ${MYSQL_DB} 2>/dev/null | awk '/wsrep_cluster_size/ {print $2}')

# If MariaDB is running and in sync, exit with status 0
if [[ ${MYSQL_STATUS} -ge 2 ]]; then
exit 0
fi

# If MariaDB is not running or out of sync, exit with status 1
exit 1

این اسکریپت وضعیت پایگاه داده MariaDB را با پرس و جو از متغیر وضعیت wsrep_cluster_size آن بررسی می کند. اگر متغیر 2 یا بیشتر باشد، فرض می‌کند که پایگاه داده در حال اجرا و هماهنگ است و با وضعیت 0 (موفقیت) خارج می‌شود. اگر متغیر کمتر از 2 باشد، فرض می کند پایگاه داده در حال اجرا نیست یا هماهنگ نیست و با وضعیت 1 (شکست) خارج می شود.

MariaDB Connect Engine is a feature of MariaDB that allows users to connect to external data sources and treat them as if they were regular tables in a MariaDB database. This capability is particularly useful for integrating data from various sources without the need to import it into the database. Here are some key points about the MariaDB Connect Engine:

Data Sources: The Connect Engine can connect to a variety of data sources, including other databases (like MySQL, PostgreSQL, and Oracle), NoSQL databases, flat files (CSV, JSON, etc.), and even web services.

Virtual Tables: When you connect to an external data source, the Connect Engine creates virtual tables that represent the data in those sources. You can then perform SQL queries on these virtual tables just like you would with regular tables in MariaDB.

Data Federation: This feature allows for data federation, meaning you can query and join data from multiple sources in a single SQL statement. This is particularly useful for reporting and analytics where data is spread across different systems.

Configuration: To use the Connect Engine, you need to configure it properly by defining the connection parameters and the structure of the external data. This is typically done using SQL commands to create a table that specifies the connection details.

Performance: While the Connect Engine provides flexibility, performance can vary depending on the external data source and the complexity of the queries. It's important to consider the performance implications when designing your data architecture.

Use Cases: Common use cases for the Connect Engine include data integration, reporting, and analytics, where organizations need to access and analyze data from multiple disparate sources without duplicating data.

Installation: The Connect Engine is not enabled by default in all MariaDB installations, so you may need to install it separately or enable it in your MariaDB configuration.

Overall, the MariaDB Connect Engine is a powerful tool for organizations looking to integrate and analyze data from various sources seamlessly.
