Detailed Description

A set of input parameters for alterSystemProperties(const AlterSystemPropertiesRequest&) const.

The alterSystemProperties(const AlterSystemPropertiesRequest&) const endpoint is primarily used to simplify the testing of the system and is not expected to be used during normal execution. Commands are given through the propertyUpdatesMap whose keys are commands and values are strings representing integer values (for example '8000') or boolean values ('true' or 'false').

Parameters

[in]	propertyUpdatesMap_	Map containing the properties of the system to be updated. Error if empty. gpudb::alter_system_properties_sm_omp_threads: Set the number of OpenMP threads that will be used to service filter & aggregation requests against collections to the specified integer value. gpudb::alter_system_properties_kernel_omp_threads: Set the number of kernel OpenMP threads to the specified integer value. gpudb::alter_system_properties_concurrent_kernel_execution: Enables concurrent kernel execution if the value is true and disables it if the value is false. gpudb::alter_system_properties_true gpudb::alter_system_properties_false gpudb::alter_system_properties_chunk_size: Sets the chunk size of all new sets to the specified integer value. gpudb::alter_system_properties_execution_mode: Sets the execution_mode for kernel executions to the specified string value. Possible values are host, device, default (engine decides) or an integer value that indicates max chunk size to exec on host gpudb::alter_system_properties_flush_to_disk: Flushes any changes to any tables to the persistent store. These changes include updates to the vector store, object store, and text search store, Value string is ignored gpudb::alter_system_properties_clear_cache: Clears cached results. Useful to allow repeated timing of endpoints. Value string is ignored gpudb::alter_system_properties_communicator_test: Invoke the communicator test and report timing results. Value string is is a comma separated list of <key>= expressions. Expressions are: num_transactions=<num> where num is the number of request reply transactions to invoke per test; message_size=<bytes> where bytes is the size of the messages to send in bytes; check_values=<enabled> where if enabled is true the value of the messages received are verified. gpudb::alter_system_properties_set_message_timers_enabled: Enables the communicator test to collect additional timing statistics when the value string is true. Disables the collection when the value string is false gpudb::alter_system_properties_true gpudb::alter_system_properties_false gpudb::alter_system_properties_bulk_add_test: Invoke the bulk add test and report timing results. Value string is ignored. gpudb::alter_system_properties_network_speed: Invoke the network speed test and report timing results. Value string is a semicolon-separated list of <key>= expressions. Valid expressions are: seconds=<time> where time is the time in seconds to run the test; data_size=<size> where size is the size in bytes of the block to be transferred; threads=<number of="" threads>="">; to_ranks=<space-separated list of ranks> where the list of ranks is the ranks that rank 0 will send data to and get data from. If to_ranks is unspecified then all worker ranks are used. gpudb::alter_system_properties_request_timeout: Number of minutes after which filtering (e.g., /filter) and aggregating (e.g., /aggregate/groupby) queries will timeout. The default value is '20'. gpudb::alter_system_properties_max_get_records_size: The maximum number of records the database will serve for a given data retrieval call. The default value is '20000'. gpudb::alter_system_properties_memory_allocation_limit_mb: Set the memory allocation limit for all rank processes in megabytes, 0 means no limit. Overrides any individual rank memory allocation limits. The default value is '0'. gpudb::alter_system_properties_enable_audit: Enable or disable auditing. gpudb::alter_system_properties_audit_headers: Enable or disable auditing of request headers. gpudb::alter_system_properties_audit_body: Enable or disable auditing of request bodies. gpudb::alter_system_properties_audit_data: Enable or disable auditing of request data. gpudb::alter_system_properties_enable_job_manager: Enable JobManager to enforce processing of requests in the order received. gpudb::alter_system_properties_chunk_cache_enabled: Enable chunk level query caching. Flushes the chunk cache when value is false gpudb::alter_system_properties_chunk_cache_size: Size of the chunk cache in bytes. The default value is '10000000'.
[in]	options_	Optional parameters.
