[Maria-discuss] [Maria Discuss] Building from source failing on Mac OS X complaining of librarymariadb

[Maria-discuss] Single-threaded DDL limitation still present in Galera?
by Artem Russakovskii 12 Aug '20

12 Aug '20

Hi, On this page https://mariadb.com/kb/en/mariadb-galera-cluster-known-limitations/, a user in 2017 pointed out the following: 3 years, 3 months ago Björn Schneider <https://mariadb.com/kb/user/id/4916> Schema changes of large tables in Galera <https://mariadb.com/kb/en/mariadb-galera-cluster-known-limitations/#comment…> You should be warned that every DDL statement executed on a Galera cluster will per default BLOCK the complete cluster (not only the table, or even just the database the table resides in)! This is the default "Total Order Isolation" (TOI) mode. The DDL statements can't be killed - once issued, it will run until completed or an error occurs. Issuing e.g. a column-altering DDL statement on a large table will take the complete cluster out of commission until every node has completed the migration. Only some operations (e.g. changing DEFAULT values) are always short-timed and won't interefere with the cluster's opperations. Long-running, cluster-blocking DDL are of course a no-go on a productive system. To resolve this issue, there are several resulutions; Percona, for example, provides a script to "online" migrate a table (pt-online-schema-change), or you can use the "Rolling Schema Upgrade" (RSU) for data-compatible changes. More about that in the Galera documentation. In my opionion, this behaviour should definitely added as "observation" to this page - it's definitely not something you'd expect coming from a "normal" MariaDB/MySQL system. We're considering moving to a cluster environment from a 1 master - 3 slave configuration that has proven inflexible, but such a severe limitation seems unusable in production. Is this still the case in 2020? What is the reasoning behind such an architectural decision, if so? Thank you.

[Maria-discuss] Test failures in my build of MariaDB 10.5.4
by Chris Ross (cross2) 08 Aug '20

08 Aug '20

I am building MariaDB 10.5.4 from source with the cmake options shown below. I am running mtr with --skip-test-list=unstable-tests, but still seeing multiple failures: Failing test(s): csv.read_only main.flush_logs_not_windows main.mysqld--help perfschema.bad_option unit.conc_charset I can copy and paste many sections of the stdout.log and specific files, but wanted to ask if this is the right forum to pursue these. These seem pretty core (main.mysqld--help, which reported ‘mysqltest: Result length mismatch‘ after a small unified diff output showing only some numeric value differing), so I’m not sure why I would be getting these. Thanks. Guidance appreciated. - Chris Cmake I used to build: cmake -DBUILD_CONFIG=mysql_release -DAWS_SDK_EXTERNAL_PROJECT=OFF -DCMAKE_INSTALL_PREFIX:PATH=/usr \ -DINSTALL_LAYOUT=RPM -DINSTALL_PLUGINDIR=lib64/plugin -DINSTALL_SYSCONFDIR="" -DINSTALL_MYSQLTESTDIR="" \ -DWITH_EMBEDDED_SERVER=NO -DWITH_JEMALLOC=OFF -DWITH_PCRE=auto -DWITH_SSL=system -DWITH_ZLIB=system \ -DWITH_WSREP=OFF -DPLUGIN_WSREP_INFO=NO -DPLUGIN_AUTH_TEST_PLUGIN=NO -DPLUGIN_FUNC_TEST=NO \ -DPLUGIN_TYPE_TEST=NO -DPLUGIN_TEST_SQL_DISCOVERY=NO -DPLUGIN_TEST_VERSIONING=NO -DPLUGIN_BLACKHOLE=NO \ -DPLUGIN_CONNECT=NO -DPLUGIN_EXAMPLE=NO -DPLUGIN_EXAMPLE_KEY_MANAGEMENT=NO -DPLUGIN_FTEXAMPLE=NO \ -DPLUGIN_FEDERATED=NO -DPLUGIN_FEDERATEDX=NO -DPLUGIN_MROONGA=NO -DMRN_GROONGA_EMBED=OFF -DPLUGIN_S3=NO \ -DPLUGIN_SPIDER=NO -DPLUGIN_SPHINX=NO -DPLUGIN_TOKUDB=NO -DPLUGIN_ROCKSDB=NO -DCMAKE_BUILD_TYPE=Debug

[Maria-discuss] Testing Slave's data integrity

Good afternoon, I have a couple slaves that I have set up over the last year. Is there a way to perhaps compare them to the master on a database or table level to ensure their integrity? Thanks

[Maria-discuss] MariaDbConnector 1.x -> 2.6, problem updating/inserting Torque objects
by Clemens Wyss - MySign AG 22 Jul '20

22 Jul '20

We are about to update MariaDbConnector from 1.x to 2.6. Having a lot of legacy code we (still) make use of Apache Torque (and Village 1.5.3) "on top" of the connector. Option(s) we had to activate so far was/is: useOldAliasMetadataBehavior=true Problem: Updating/inserting (Torque objects) Records does not work anymore with the new connector. Debugging reveals that it is due to the resultSetConcurrency being CONCUR_READ_ONLY when trying to update/insert a Record. Torque seems to initially select the Record to be updated before effetively updating. Hence the Schema "attached" to the record has CONCUR_READ_ONLY >record.schema().column(i).readOnly() // true ☹ I could patch org.mariadb.jdbc.internal.com.read.resultset. SelectResultSet# getMetaData to return > new MariaDbResultSetMetaData(columnsInformation, options, forceAlias, false ) instead of >new MariaDbResultSetMetaData(columnsInformation, options, forceAlias, true ) but that doesn't really feel "right" 😉 I'd appreciate any hint/advice regarding this issue Thx Clemens

by Clemens Wyss - MySign AG 21 Jul '20

The patch would of course be > new MariaDbResultSetMetaData(columnsInformation, options, forceAlias, ** true ** ) instead of >new MariaDbResultSetMetaData(columnsInformation, options, forceAlias, false ) i.e. forcing "updatable" to true Another note/detail: we make use of the Tomcat db connection pool
