Re: a scheme for the future mysql-protocol, Re: [ANN] New PBXT/MyBS release enables JDBC-based BLOB streaming!
Hi Chad, Yes, I agree. This is a really good idea. I think that it makes a lot of sense to make streaming part of the standard MySQL protocol. Your suggestion solves the problem that always comes with a transition to a new protocol.

[ANN] New PBXT/MyBS release enables JDBC-based BLOB streaming!
Hi All, I have just released PBXT 0.9.90 and MyBS version 0.5.03. PBXT is a transactional storage engine for MySQL (http://www.primebase.com/xt), and MyBS is a storage engine that enables streaming of BLOB data directly in and out of a MySQL database (http://www.blobstreaming.org) . For this release I have completed changes to the MySQL Connector/J 5.0.7, to allow BLOB data to be transparently stored and retrieved from the MyBS BLOB repository. The new version of the driver is called MySQL Connector/J SE (streaming enabled). Uploading a BLOB is as simple as using setBinaryStream() or setBlob() on INSERT. By using getBinaryStream() or getBlob() after a SELECT you get direct access to the data stream coming from the repository. More information and some examples are provided in the documentation at: http://www.blobstreaming.org/documentation. To try this out you need to install the latest versions of PBXT and MyBS. Both are available from: http://www.blobstreaming.org/download. Binary versions of the storage engines are also available for MySQL 5.1.22 running on 32-bit Linux and x86 Mac OS X. The modified version of the JDBC source code is included in the MyBS source code distribution, but the driver can also be downloaded here: http:// www.blobstreaming.org/download/mysql-connector-java-5.0.7se-bin.jar. I have included a small test program, TestJDBC.java, as part of the JDBC driver. So once you have installed the engines, you can test BLOB streaming as follows: java -cp mysql-connector-java-5.0.7se-bin.jar TestJDBC TestJDBC connects to a local MySQL server, creates a PBXT table and tests INSERT and SELECT of rows containing BLOBs. The program also serves as an example of how to do BLOB streaming with JDBC. To get started quickly, the most important things to note are: * Set EnableBlobStreaming=true in your JDBC connection URL. * Streamable BLOBs can only be stored in LONGBLOB columns in PBXT tables. * Use setBinaryStream(), setAsciiStream or setBlob() and specify the length to upload a BLOB. As usual, any comments, questions or bug reports can be sent directly to me: paul-dot-mccullagh-at-primebase-dot-com. Make sure you put the word PBXT or MyBS in the e-mail title to make it through my spam filter! :) Best regards, Paul -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
