public static final class AlterSystemPropertiesRequest.PropertyUpdatesMap
extends Object

Map containing the properties of the system to be updated. Error if empty.

• 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.
• KERNEL_OMP_THREADS: Set the number of kernel OpenMP threads to the specified integer value.
• CONCURRENT_KERNEL_EXECUTION: Enables concurrent kernel execution if the value is true and disables it if the value is false. Supported values:
  • TRUE
  • FALSE
• CHUNK_SIZE: Sets the chunk size of all new sets to the specified integer value.
• 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
• CLEAR_CACHE: Clears cached results. Useful to allow repeated timing of endpoints. Value string is ignored
• COMMUNICATOR_TEST: Invoke the communicator test and report timing results. Value string is is a comma separated list of = expressions. Expressions are: num_transactions= where num is the number of request reply transactions to invoke per test; message_size= where bytes is the size of the messages to send in bytes; check_values= where if enabled is true the value of the messages received are verified.
• 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 Supported values:
  • TRUE
  • FALSE
• BULK_ADD_TEST: Invoke the bulk add test and report timing results. Value string is ignored.
• NETWORK_SPEED: Invoke the network speed test and report timing results. Value string is a semicolon-separated list of = expressions. Valid expressions are: seconds= where time is the time in seconds to run the test; data_size= where size is the size in bytes of the block to be transferred; threads=; to_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.
• REQUEST_TIMEOUT: Number of minutes after which filtering (e.g., GPUdb.filter(FilterRequest)) and aggregating (e.g., GPUdb.aggregateGroupByRaw(AggregateGroupByRequest)) queries will timeout.
• MAX_GET_RECORDS_SIZE: The maximum number of records the database will serve for a given data retrieval call

A set of string constants for the parameter propertyUpdatesMap.
