[Maria-developers] WL#215 New (by Monty): Add functional indexes

----------------------------------------------------------------------- WORKLOG TASK -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- TASK...........: Add functional indexes CREATION DATE..: Thu, 30 Jun 2011, 16:17 SUPERVISOR.....: Monty IMPLEMENTOR....: COPIES TO......: CATEGORY.......: Server-Sprint TASK ID........: 215 (http://askmonty.org/worklog/?tid=215) VERSION........: Server-5.6 STATUS.........: Un-Assigned PRIORITY.......: 60 WORKED HOURS...: 0 ESTIMATE.......: 200 (hours remain) ORIG. ESTIMATE.: 200 PROGRESS NOTES: DESCRIPTION: Add support for functional indexes. This is needed for MWL#34 Dynamic columns. The idea would be to extend the handler interface with a callback function that provides the handler with a key in normal key-read format of the index entry. In addition we need to enhance the optimizer to recognize the function used for the functional index parts so that it can use the index.

[Maria-developers] WL#214 New (by Monty): Make Indexes first level objects

----------------------------------------------------------------------- WORKLOG TASK -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- TASK...........: Make Indexes first level objects CREATION DATE..: Thu, 30 Jun 2011, 16:11 SUPERVISOR.....: IMPLEMENTOR....: COPIES TO......: CATEGORY.......: Maria-RawIdeaBin TASK ID........: 214 (http://askmonty.org/worklog/?tid=214) VERSION........: Server-5.3 STATUS.........: Un-Assigned PRIORITY.......: 60 WORKED HOURS...: 0 ESTIMATE.......: 0 (hours remain) ORIG. ESTIMATE.: 0 PROGRESS NOTES: DESCRIPTION: An index should be able to exist as an object that is not tied to a physical table. That would allow for indexes that are global to a > partition, and for functional indexes or indexes on virtual columns. The above is extremely hard to do as Indexes are very closely tied to storage engines. What is easier to do is to do functional indexes, where the storage engine will ask MySQL for the index data for a row.

[Maria-developers] WL#212 New (by Monty): Compressed binary log

ESTIMATE.: 80 PROGRESS NOTES: DESCRIPTION: Compress the binary log to make it smaller. The following options exists: a) Compress old binary log when they are not in use. On access from delayed slave, decompress it from start to memory and feed the slave the data from the uncompressed stream. b) Compress each binary log event separately with a format: <length><data>. Ship the binary log in the compressed format. I assume that b) is much easier to do.

We'd like to have a command that can be issues to an empty database, will download the data from a master (or a co-slave), and then attach the new slave to the master (using the configuration provided on the command line or by the co-slave). Requirements: * Should be done at SQL level. * With progress report. * The data should move at disk speed; No index creation, ship binary index data from the co-slave or master.
