Hi guys, i'm running slackware 14.1, i upgrade to slackware-current, and downloaded the mariadb-10.0.11 x64 with glibc 2.19 the point is... whern i run mysql, it requires a 'deprecated' library, libtinfo.so.5, this one was replaced by libncurses.so.5 there's something we could help here? today i execute a symlink to solve this problem, but since libtinfo is deprecated, should we update our compile line? -- Roberto Spadim SPAEmpresarial Eng.

[Maria-discuss] MariaDB encryption
by Jonas Oreland 06 Jun '14

06 Jun '14

Hi there, I read this blog post http://monty-says.blogspot.com/2014/05/for-your-eyes-only-or-adding-better.… and wanted to inform you that we at Google has developed on-disk/block-level encryption for Innodb, aria (as used by temporary tables), binlogs and temp-files. The code is not yet published, but we expect it to be within a few weeks or so. We (of course?) think that it would be better if you instead of developing new code spent the time testing/reviewing ours. I'm happy to answer questions on the topic, and will let you know once we've published it. /Jonas ps. Ian talked about this at percona, https://www.percona.com/live/mysql-conference-2014/sessions/privacy-and-sec…

[Maria-discuss] New Question: Spider storage engine condition pushdown
by AskMonty KB 04 Jun '14

04 Jun '14

Hello, A new question has been asked in "Spider" by lokeshkumar-p-417: -------------------------------- Hi, We are using Spider storage engine for sharding with MariaDB. MariaDB version - 10.0.10 Spider version - 3.2 Platform - CentOs 6.5 Problem: ---------------- We have a simple scenario, where we have a table with Spider storage engine, which is list partitioned based on a column. Each partition is pointing to a shard. Whenever a query is fired from the Master database with a WHERE clause, the WHERE condition is not being pushed to the shard, instead all the data from shard is being transferred to the DB where Spider storage engine is present. I came to know that this issue has been fixed in the Spider storage engine, and also I verified the MariaDB 10.0.9-spider-3.2 source code and it has cond_push and cond_pop functions. Please let me know how else can I enable this condition pushdown. Regards, -Lokesh Kumar -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/spider-storage-engine-condition-pushdown/

[Maria-discuss] PERFORMANCE_SCHEMA to be disabled in 10.0 (10.0.12)
by Colin Charles 03 Jun '14

03 Jun '14

Hi all, Recently there was chat about how PERFORMANCE_SCHEMA was enabled by mistake and it should be disabled in the 10.0 series. I'm curious - how many of you are using PERFORMANCE_SCHEMA? Is it a problem to turn it on, if you use it? I'm referring to: https://mariadb.atlassian.net/browse/MDEV-6249 Looking from the webscalesql list, there are examples of performance degradation: https://groups.google.com/d/msg/webscalesql/B-4bPIb8mHI/eUNsl0lSfbMJ https://groups.google.com/d/msg/webscalesql/B-4bPIb8mHI/-YZMMCuPw3QJ quote: "Our perf testing agrees with your assessment (we see about a 5%-6% perf hit when it's included and on, and a 2%-3% hit when it's included but off)" Please discuss this, either here or on MDEV-6249 Thanks cheers, -colin -- Colin Charles, Chief Evangelist, SkySQL - The MariaDB Company blog: http://bytebot.net/blog/| t: +6-012-204-3201 | Skype: colincharles

Yes, we know its already a GA, but this feature will be turned off by default, and the code is safely encapsulated. If you are not using Fusion-io or do not turn it on, there is no effect to you.

[Maria-discuss] Does the Cassandra storage engine support CQL3 created tables?
by Mohammed Guller 03 Jun '14

03 Jun '14

I am able to access a Cassandra column family created with COMPACT storage directive from MariaDB (v10.0.10). However, it does not seem to recognize regular CFs created using CQL3. I am not sure whether I am missing some configuration step in the Cassandra storage engine or it still does not support regular CQL3 CFs. Has anyone able to make Cassandra SE work with regular CQL3 CFs?
