public final class ConfigurationVariables
extends com.oracle.bmc.http.client.internal.ExplicitlySetBmcModel
User-defined service variables.
Note: Objects should always be created or deserialized using the ConfigurationVariables.Builder. This model
distinguishes fields that are null because they are unset from fields that are explicitly
set to null. This is done in the setter methods of the ConfigurationVariables.Builder, which maintain a
set of all explicitly set fields called ConfigurationVariables.Builder.__explicitlySet__. The hashCode() and equals(Object) methods are implemented to take the explicitly set
fields into account. The constructor, on the other hand, does not take the explicitly set fields
into account (since the constructor cannot distinguish explicit null from unset null).

Setting hypergraph_optimizer=on for cloud builds below 9.0.0 will fail.
optimizerSwitch corresponds to the MySQL Server System variable [optimizer_switch] (https://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html#sysvar_optimizer_switch).
public String getReplicaTypeConversions()
From MySQL 8.0.26, use replica_type_conversions in place of slave_type_conversions, which is deprecated from that release. In releases before MySQL 8.0.26, use slave_type_conversions.
replica_type_conversions controls the type conversion mode in effect on the replica when using row-based replication. Its value is a comma-delimited set of zero or more elements from the list: ALL_LOSSY, ALL_NON_LOSSY, ALL_SIGNED, ALL_UNSIGNED. Set this variable to an empty string to disallow type conversions between the source and the replica. Setting this variable takes effect for all replication channels immediately, including running channels.
replica_type_conversions corresponds to the MySQL Replica Server Options variable [replica_type_conversions] (https://dev.mysql.com/doc/refman/8.0/en/replication-options-replica.html#sysvar_replica_type_conversions).
public Integer getReplicaParallelWorkers()
Beginning with MySQL 8.0.26, slave_parallel_workers is deprecated, and you should use replica_parallel_workers instead. (Prior to MySQL 8.0.26, you must use slave_parallel_workers to set the number of applier threads.)
replicaParallelWorkers corresponds to the MySQL Replica Server Options variable [replica_parallel_workers] (https://dev.mysql.com/doc/refman/8.0/en/replication-options-replica.html#sysvar_replica_parallel_workers).
public Boolean getSkipNameResolve()
Whether to resolve host names when checking client connections. If this variable is OFF, mysqld resolves host names when checking client connections. If it is ON, mysqld uses only IP numbers; in this case, all Host column values in the grant tables must be IP addresses. See Section 7.1.12.3, “DNS Lookups and the Host Cache”.
skipNameResolve corresponds to the MySQL Server System variable [skip_name_resolve] (https://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html#sysvar_skip_name_resolve).
public Long getMaxUserConnections()
The maximum number of simultaneous connections permitted to any given MySQL user account. A value of 0 (the default) means “no limit.” This variable has a global value that can be set at server startup or runtime. It also has a read-only session value that indicates the effective simultaneous-connection limit that applies to the account associated with the current session.
maxUserConnections corresponds to the MySQL Server System variable [max_user_connections] (https://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html#sysvar_max_user_connections).
public Long getJoinBufferSize()
The minimum size of the buffer that is used for plain index scans, range index scans, and joins that do not use indexes and thus perform full table scans. In MySQL 8.0.18 and later, this variable also controls the amount of memory used for hash joins. Normally, the best way to get fast joins is to add indexes. Increase the value of join_buffer_size to get a faster full join when adding indexes is not possible. One join buffer is allocated for each full join between two tables. For a complex join between several tables for which indexes are not used, multiple join buffers might be necessary.
joinBufferSize corresponds to the MySQL Server System variable [join_buffer_size] (https://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html#sysvar_join_buffer_size).
public Long getMaxSeeksForKey()
Limit the assumed maximum number of seeks when looking up rows based on a key. The MySQL optimizer assumes that no more than this number of key seeks are required when searching for matching rows in a table by scanning an index, regardless of the actual cardinality of the index (see Section 15.7.7.22, “SHOW INDEX Statement”). By setting this to a low value (say, 100), you can force MySQL to prefer indexes instead of table scans.
maxSeeksForKey corresponds to the MySQL Server System variable [max_seeks_for_key] (https://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html#sysvar_max_seeks_for_key).
public Long getRangeOptimizerMaxMemSize()
The limit on memory consumption for the range optimizer. A value of 0 means “no limit.” If an execution plan considered by the optimizer uses the range access method but the optimizer estimates that the amount of memory needed for this method would exceed the limit, it abandons the plan and considers other plans.
rangeOptimizerMaxMemSize corresponds to the MySQL Server System variable [range_optimizer_max_mem_size] (https://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html#sysvar_range_optimizer_max_mem_size).
public Integer getAutoIncrementIncrement()
auto_increment_increment and auto_increment_offset are intended for use with circular (source-to-source) replication, and can be used to control the operation of AUTO_INCREMENT columns. Both variables have global and session values, and each can assume an integer value between 1 and 65,535 inclusive.
autoIncrementIncrement corresponds to the MySQL Replication Source Options variable [auto_increment_increment] (https://dev.mysql.com/doc/refman/8.0/en/replication-options-source.html#sysvar_auto_increment_increment).
public Integer getAutoIncrementOffset()
This variable has a default value of 1. If it is left with its default value, and Group Replication is started on the server in multi-primary mode, it is changed to the server ID.
autoIncrementOffset corresponds to the MySQL Replication Source Options variable [auto_increment_offset] (https://dev.mysql.com/doc/refman/8.0/en/replication-options-source.html#sysvar_auto_increment_offset).
public Integer getInnodbAutoincLockMode()
The lock mode to use for generating auto-increment values. Permissible values are 0, 1, or 2, for traditional, consecutive, or interleaved, respectively.
innodbAutoincLockMode corresponds to the MySQL InnoDB Startup Options and System Variables [innodb_autoinc_lock_mode] (https://dev.mysql.com/doc/refman/8.0/en/innodb-parameters.html#sysvar_innodb_autoinc_lock_mode).
public Boolean getInnodbRollbackOnTimeout()
InnoDB rolls back only the last statement on a transaction timeout by default. If –innodb-rollback-on-timeout is specified, a transaction timeout causes InnoDB to abort and roll back the entire transaction.
innodbRollbackOnTimeout corresponds to the MySQL InnoDB Startup Options and System Variables [innodb_rollback_on_timeout] (https://dev.mysql.com/doc/refman/8.0/en/innodb-parameters.html#sysvar_innodb_rollback_on_timeout).
public Long getInnodbOnlineAlterLogMaxSize()
Specifies an upper limit in bytes on the size of the temporary log files used during online DDL operations for InnoDB tables. There is one such log file for each index being created or table being altered. This log file stores data inserted, updated, or deleted in the table during the DDL operation.
innodbOnlineAlterLogMaxSize corresponds to the MySQL InnoDB Startup Options and System Variables [innodb_online_alter_log_max_size] (https://dev.mysql.com/doc/refman/8.0/en/innodb-parameters.html#sysvar_innodb_online_alter_log_max_size).
public Integer getInnodbSortBufferSize()
This variable defines:
The sort buffer size for online DDL operations that create or rebuild secondary indexes. However, as of MySQL 8.0.27, this responsibility is subsumed by the innodb_ddl_buffer_size variable.
The amount by which the temporary log file is extended when recording concurrent DML during an online DDL operation, and the size of the temporary log file read buffer and write buffer.
innodbSortBufferSize corresponds to the MySQL InnoDB Startup Options and System Variables [innodb_sort_buffer_size] (https://dev.mysql.com/doc/refman/8.0/en/innodb-parameters.html#sysvar_innodb_sort_buffer_size).
public Boolean getInnodbNumaInterleave()
Enables the NUMA interleave memory policy for allocation of the InnoDB buffer pool. When innodb_numa_interleave is enabled, the NUMA memory policy is set to MPOL_INTERLEAVE for the mysqld process. After the InnoDB buffer pool is allocated, the NUMA memory policy is set back to MPOL_DEFAULT. For the innodb_numa_interleave option to be available, MySQL must be compiled on a NUMA-enabled Linux system.
innodbNumaInterleave corresponds to the MySQL InnoDB Startup Options and System Variables [innodb_numa_interleave] (https://dev.mysql.com/doc/refman/8.0/en/innodb-parameters.html#sysvar_innodb_numa_interleave).
public Integer getThreadPoolSize()
The number of thread groups in the thread pool. This is the most important parameter controlling thread pool performance. It affects how many statements can execute simultaneously. If a value outside the range of permissible values is specified, the thread pool plugin does not load and the server writes a message to the error log.
threadPoolSize corresponds to the MySQL Server System variable [thread_pool_size] (https://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html#sysvar_thread_pool_size).
public Integer getLongQueryTime()
If a query takes longer than this many seconds, the server increments the Slow_queries status variable. If the slow query log is enabled, the query is logged to the slow query log file. This value is measured in real time, not CPU time, so a query that is under the threshold on a lightly loaded system might be above the threshold on a heavily loaded one.
longQueryTime corresponds to the MySQL Server System variable [long_query_time] (https://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html#sysvar_long_query_time).
