The partitioning storage engine has been updated to support all the new Spider features including: * Direct join support. This allows Spider to do JOINS and GROUP BYs internally. * Direct update and delete. * Direct aggregates. * [slave\_transaction\_retry\_errors](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/ha-and-performance/standard-replication/replication-and-binary-log-system-variables) and [slave-transaction-retry-interval](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/ha-and-performance/standard-replication/replication-and-binary-log-system-variables) allow more control over handling delays or conflicts when applying binary logs. Most of the features were done as part of [MDEV-7698](https://jira.mariadb.org/browse/MDEV-7698). #### OQGRAPH * [OQGraph](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-usage/storage-engines/oqgraph-storage-engine) now supports the "leaves" algorithm ([MDEV-11271](https://jira.mariadb.org/browse/MDEV-11271)) — contribution by Heinz Wiesinger #### Partition Engine * Numerous improvements for the partition engine ([MDEV-7698](https://jira.mariadb.org/browse/MDEV-7698)) — contribution by Kentoku Shiba * Full text support. * Multi-range-read (Gives better performance when handling multiple ranges). * Support for condition pushdown. * HANDLER support * Aggregate pushdown * Bulk update/delete ### Information Schema * The Information Schema is optimized to use much less memory when selecting from [INFORMATION\_SCHEMA.TABLES](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/system-tables/information-schema/information-schema-tables/information-schema-tables-table) or any other table with many [VARCHAR](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/data-types/string-data-types/varchar) or [TEXT](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/data-types/string-data-types/text) columns ([MDEV-14275](https://jira.mariadb.org/browse/MDEV-14275)) * The [Information Schema Columns table](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/system-tables/information-schema/information-schema-tables/information-schema-columns-table) now displays [system versioning](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/reference/sql-structure/temporal-tables/system-versioned-tables) info in the EXTRA column - [MDEV-15062](https://jira.mariadb.org/browse/MDEV-15062) ### Logging * Disable logging of certain statements to the [general log](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-management/server-monitoring-logs/general-query-log) or the [slow query log](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-management/server-monitoring-logs/slow-query-log) with the [log\_disabled\_statements](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-management/variables-and-modes/server-system-variables#log_disabled_statements) and [log\_slow\_disabled\_statements](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-management/variables-and-modes/server-system-variables#log_slow_disabled_statements) system variables. * A new option to [log\_slow\_filter](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-management/variables-and-modes/server-system-variables#log_slow_filter), `filsort_priority_queue`. ### Replication * Per-engine mysql.gtid\_slave\_pos tables ([MDEV-12179](https://jira.mariadb.org/browse/MDEV-12179)) — Implemented by Kristian Nielsen funded by Booking.com. ### Data Type API 10.3 continues refactoring for the data type API started in 10.2, which will make it possible to have user data type plugins. This work is still in progress (see [MDEV-4912](https://jira.mariadb.org/browse/MDEV-4912) for the current status and subtasks). Most of the task in this category do not change the server behavior. Some tasks do have a [visible effect](https://mariadb.com/docs/release-notes/community-server/old-releases/10.3.0#data-type-api). ### Idle Transactions Connections with idle transactions can be automatically killed after a specified time period by means of the [idle\_transaction\_timeout](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-management/variables-and-modes/server-system-variables#idle_transaction_timeout), [idle\_readonly\_transaction\_timeout](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-management/variables-and-modes/server-system-variables#idle_readonly_transaction_timeout) and [idle\_write\_transaction\_timeout](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/server-management/variables-and-modes/server-system-variables#idle_write_transaction_timeout) system variables. ### System Variables For a list of all new variables, see [System Variables Added in MariaDB 10.3](https://app.gitbook.com/s/SsmexDFPv2xG2OTyO5yV/ha-and-performance/optimization-and-tuning/system-variables/system-and-status-variables-added-by-major-release/system-and-status-variables-added-by-major-unmaintained-release/system-variables-added-in-mariadb-10-3)
