[Maria-discuss] Master slave
by Richard Couture 27 Jul '13

27 Jul '13

Is it possible to set up replication in such a manner as to permit writing records to either a master or a slave replica? We want to set up a fail safe replica that can easily take over when our connection to the main replica fails, which, unfortunately, is fairly often. I read a document, some time ago which mentioned several types of replication, i.e.: by record, by table ... and the pitfalls, like IDs not necessarily matching... which confused me more than anything else... Can someone point me to some good documentation to enable me to pick the correct type of replication that I need to accomplish my task?? Thanks Richard -- LinuxCabal Asociación Civil Ing.

[Maria-discuss] New Question: Multi-threading and Statement.cancel()
by AskMonty KB 19 Jul '13

19 Jul '13

Hello, A new question has been asked in "MariaDB Java Client" by rstepanski: -------------------------------- Attempting to execute queries on multiple threads (10 to 20) with the ability to cancel each Thread's unique Statement mid execution from a separate thread. However, when sharing a single Connection among all threads for their Statement creation, a cancel() on one Statement will cause other thread's executeQuery() to throw a "Query execution was interrupted". Switching to per thread Connections and a thread pool, the cancel() will sometimes fail with "Unknown thread id: xx". I'm assuming this occurs when a thread previously used to work with another connection attempts to cancel() another. This had worked previously with MySql jdbc (and still does with MySql jdbc + MariaDb server). The queries themselves are single table, limited/offset, selects. Where clauses would generally be related: query 1: like 'a%' query 2: like 'ab%' query 3: like 'abc%' With each previous query being cancelled when a more specific query was available. Any comments/suggestions appreciated. Thanks! -------------------------------- To view or answer this question please visit: http://kb.askmonty.org/en/multi-threading-and-statementcancel/

[Maria-discuss] upgrading from mariadb 5.5.31 to mariadb 5.5.32 with innodb engine
by Gabriel Sosa 18 Jul '13

18 Jul '13

Hello! few days ago we realized we got cached by the bug MDEV-4754 [1] . Today mariadb 5.5.32 has been released but among the notable Information the mysql bug #69623 [2] is mentioned in case you have the table using the Innodb engine. per our information: | innodb_data_file_path | ibdata1:100M:autoextend | | innodb_data_home_dir | /var/lib/mysql/innodb | | innodb_file_per_table | ON | | innodb_version | 5.5.31-MariaDB-30.2 | I think we fit exactly in that scenario but I need some help to confirm this and be sure can *upgrade* without issues or that we should wait for another release that fix this. Any clue? Thanks!
