[#9838] feat(storage): Add JDBC storage backend for partition statistics
(#9779)
## What changes were proposed in this pull request?
This PR adds JDBC (MySQL, PostgreSQL, H2) as an alternative storage
backend for partition statistics, complementing the existing Lance
storage implementation.
## Why are the changes needed?
Fix #9838
Currently, partition statistics can only be stored using Lance format.
This PR adds JDBC as an option for users who:
- Prefer relational database storage
- Already have database infrastructure (MySQL, PostgreSQL, H2)
- Need transactional guarantees for statistics updates
- Want to use existing database backup/recovery tools
- Want to use the same database as Gravitino's entity storage
## Does this PR introduce any user-facing change?
No breaking changes. The storage backend is pluggable via configuration:
```properties
# Use JDBC storage (default is Lance)
gravitino.stats.partition.storageFactoryClass =
org.apache.gravitino.stats.storage.JdbcPartitionStatisticStorageFactory
# JDBC connection settings
gravitino.stats.partition.storageOption.jdbcUrl =
jdbc:mysql://localhost:3306/gravitino
gravitino.stats.partition.storageOption.jdbcUser = root
gravitino.stats.partition.storageOption.jdbcPassword = gravitino
gravitino.stats.partition.storageOption.jdbcDriver =
com.mysql.cj.jdbc.Driver
```

+#### JDBC Storage (Default)
+
+Starting from version 1.2.0, Gravitino uses JDBC-based storage as the default
partition statistics storage backend.
+This provides a reliable, production-ready solution that supports multiple
database backends:
+
+- **MySQL** (recommended for production)
+- **PostgreSQL**
+- **H2** (suitable for testing and development)
+
+To use JDBC storage, configure the following options by adding the prefix
`gravitino.stats.partition.storageOption.`:
+
+| Configuration item |
Description | Default
value | Required | Since version |
+|-----------------------------------------------------------------|--------------------------------------------------------------------|----------------------------|----------|---------------|

| Yes | 1.2.0 |
+| `gravitino.stats.partition.storageOption.jdbcUser` | Database
username | None
| Yes | 1.2.0 |
+| `gravitino.stats.partition.storageOption.jdbcPassword` | Database

| Yes | 1.2.0 |
+| `gravitino.stats.partition.storageOption.jdbcDriver` | JDBC

`com.mysql.cj.jdbc.Driver` | No | 1.2.0 |
+| `gravitino.stats.partition.storageOption.poolMaxSize` | Maximum
connection pool size | `10`
| No | 1.2.0 |
+| `gravitino.stats.partition.storageOption.poolMinIdle` | Minimum
idle connections in pool | `2`
| No | 1.2.0 |
+| `gravitino.stats.partition.storageOption.connectionTimeoutMs` | Connection

| No | 1.2.0 |

+**Example MySQL Configuration:**
+
+```properties
+gravitino.stats.partition.storageFactoryClass =
org.apache.gravitino.stats.storage.JdbcPartitionStatisticStorageFactory
+gravitino.stats.partition.storageOption.jdbcUrl =
jdbc:mysql://localhost:3306/gravitino
+gravitino.stats.partition.storageOption.jdbcUser = gravitino
+gravitino.stats.partition.storageOption.jdbcPassword = gravitino123
+gravitino.stats.partition.storageOption.poolMaxSize = 20
+```
+
+**Example PostgreSQL Configuration:**
+
+```properties
+gravitino.stats.partition.storageFactoryClass =
org.apache.gravitino.stats.storage.JdbcPartitionStatisticStorageFactory
+gravitino.stats.partition.storageOption.jdbcUrl =
jdbc:postgresql://localhost:5432/gravitino
+gravitino.stats.partition.storageOption.jdbcUser = gravitino
+gravitino.stats.partition.storageOption.jdbcPassword = gravitino123
+gravitino.stats.partition.storageOption.jdbcDriver = org.postgresql.Driver
+```
+
+**Database Schema Setup:**
+
+Before using JDBC storage, you need to create the database schema. Schema
files are provided for all supported databases:
+
+- MySQL: `scripts/mysql/schema-${GRAVITINO_VERSION}-mysql.sql`
+- PostgreSQL: `scripts/postgresql/schema-${GRAVITINO_VERSION}-postgresql.sql`
+- H2: `scripts/h2/schema-${GRAVITINO_VERSION}-h2.sql`
+
+For MySQL:
+```bash
+mysql -u root -p < scripts/mysql/schema-${GRAVITINO_VERSION}-mysql.sql
+```
+
+For PostgreSQL:
+```bash
+psql -U postgres -d gravitino -f
scripts/postgresql/schema-${GRAVITINO_VERSION}-postgresql.sql
+```
+
+#### Lance Storage (Alternative)
+
If you use [Lance](https://lancedb.github.io/lance/) as the partition
statistics storage, you can set the options below, if you have other lance
storage options, you can pass it by adding prefix
`gravitino.stats.partition.storageOption.`.
For example, if you set an extra property `foo` to `bar` for Lance storage
option, you can add a configuration item
`gravitino.stats.partition.storageOption.foo` with value `bar`.
@@ -258,7 +320,14 @@ For Lance remote storage, you can refer to the document
[here](https://lancedb.g
If you have many tables with a small number of partitions, you should set a
smaller metadataFileCacheSizeBytes and indexCacheSizeBytes.
-### Implementation a custom partition storage
+**To use Lance storage, configure:**
+
+```properties
+gravitino.stats.partition.storageFactoryClass =
org.apache.gravitino.stats.storage.LancePartitionStatisticStorageFactory
+gravitino.stats.partition.storageOption.location = /data/lance
+```
+
+### Implement a custom partition storage
You can implement a custom partition storage by implementing the interface
`org.apache.gravitino.stats.storage.PartitionStatisticStorageFactory` and
setting the configuration item `gravitino.stats.partition.storageFactoryClass`
to your class name.
