Google Summer of Code What Is It? How I Got Involved The Project: BLOBStreaming Support in phpMyAdmin Mentors: Marc Delisle Paul McCullagh

What Is It?

How I Got Involved

The Project:

BLOBStreaming Support in phpMyAdmin

Mentors:

Marc Delisle

Paul McCullagh

What Is A BLOB? Binary Large Object Commonly used to store files in databases File types: MP3s, Videos, Photos, etc Advantages of BLOBs: Transactional operations Consistent Backups Disadvantages of BLOBs: BLOB columns slow down reading of tables Databases become large easily

Binary Large Object

Commonly used to store files in databases

File types: MP3s, Videos, Photos, etc

Advantages of BLOBs:

Transactional operations

Consistent Backups

Disadvantages of BLOBs:

BLOB columns slow down reading of tables

Databases become large easily

BLOBStreaming What Is It? Advantages: Avoid “dangling” references Fast backups Fast replication Better scalability Requires: MySQL, phpMyAdmin PBXT, MyBS

What Is It?

Advantages:

Avoid “dangling” references

Fast backups

Fast replication

Better scalability

Requires:

MySQL, phpMyAdmin

PBXT, MyBS

Goals of BLOBStreaming Store BLOBs of any size Stream BLOBs in and out of databases Open system usable by all storage engines Standardised client API for applications

Store BLOBs of any size

Stream BLOBs in and out of databases

Open system usable by all storage engines

Standardised client API for applications

BLOBStreaming Support in phpMyAdmin How It Works: Plugin Detection Supported Databases Detection CURL Detection Upload to BLOB Repository Streaming of BLOBs via BLOB References Removal of BLOB References

How It Works:

Plugin Detection

Supported Databases Detection

CURL Detection

Upload to BLOB Repository

Streaming of BLOBs via BLOB References

Removal of BLOB References

PROJECT DEMONSTRATION

Project Limitations CURL No uploading to BLOB Repository via FTP Upload Limitations imposed by PHP: memory_limit max_execution_time upload_max_filesize post_max_size

CURL

No uploading to BLOB Repository via FTP

Upload Limitations imposed by PHP:

memory_limit

max_execution_time

upload_max_filesize

post_max_size

Future Goals Feature Customisation Support for CURL alternatives (like wput) Upload to the BLOB repository via FTP Multipart/form-data handling

Feature Customisation

Support for CURL alternatives (like wput)

Upload to the BLOB repository via FTP

Multipart/form-data handling
