A set of options that can be set globally for the FDB API.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

LocalAddress(String)

IP:PORT

Deprecated

ClusterFile(String)

path to cluster file

Deprecated

TraceEnable(String)

path to output directory (or NULL for current working directory)

Enables trace output to a file in a directory of the clients choosing

TraceRollSize(i32)

max size of a single trace output file

Sets the maximum size in bytes of a single trace output file. This value should be in the range [0, INT64_MAX]. If the value is set to 0, there is no limit on individual file size. The default is a maximum size of 10,485,760 bytes.

TraceMaxLogsSize(i32)

max total size of trace files

Sets the maximum size of all the trace output files put together. This value should be in the range [0, INT64_MAX]. If the value is set to 0, there is no limit on the total size of the files. The default is a maximum size of 104,857,600 bytes. If the default roll size is used, this means that a maximum of 10 trace files will be written at a time.

TraceLogGroup(String)

value of the LogGroup attribute

Sets the ‘LogGroup’ attribute with the specified value for all events in the trace output files. The default log group is ‘default’.

TraceFormat(String)

Format of trace files

Select the format of the log files. xml (the default) and json are supported.

TraceClockSource(String)

Trace clock source

Select clock source for trace files. now (the default) or realtime are supported.

TraceFileIdentifier(String)

The identifier that will be part of all trace file names

Once provided, this string will be used to replace the port/PID in the log file names.

TracePartialFileSuffix(String)

Append this suffix to partially written log files. When a log file is complete, it is renamed to remove the suffix. No separator is added between the file and the suffix. If you want to add a file extension, you should include the separator - e.g. ‘.tmp’ instead of ‘tmp’ to add the ‘tmp’ extension.

Set file suffix for partially written log files.

Knob(String)

knob_name=knob_value

Set internal tuning or debugging knobs

TLSPlugin(String)

file path or linker-resolved name

Deprecated

TLSCertBytes(Vec<u8>)

certificates

Set the certificate chain

TLSCertPath(String)

file path

Set the file from which to load the certificate chain

TLSKeyBytes(Vec<u8>)

key

Set the private key corresponding to your own certificate

TLSKeyPath(String)

file path

Set the file from which to load the private key corresponding to your own certificate

TLSVerifyPeers(Vec<u8>)

verification pattern

Set the peer certificate field verification criteria

BuggifyEnable

BuggifyDisable

BuggifySectionActivatedProbability(i32)

probability expressed as a percentage between 0 and 100

Set the probability of a BUGGIFY section being active for the current execution. Only applies to code paths first traversed AFTER this option is changed.

BuggifySectionFiredProbability(i32)

probability expressed as a percentage between 0 and 100

Set the probability of an active BUGGIFY section being fired

TLSCaBytes(Vec<u8>)

ca bundle

Set the ca bundle

TLSCaPath(String)

file path

Set the file from which to load the certificate authority bundle

TLSPassword(String)

key passphrase

Set the passphrase for encrypted private key. Password should be set before setting the key for the password to be used.

DisableMultiVersionClientApi

Disables the multi-version client API and instead uses the local client directly. Must be set before setting up the network.

CallbacksOnExternalThreads

If set, callbacks from external client libraries can be called from threads created by the FoundationDB client library. Otherwise, callbacks will be called from either the thread used to add the callback or the network thread. Setting this option can improve performance when connected using an external client, but may not be safe to use in all environments. Must be set before setting up the network. WARNING: This feature is considered experimental at this time.

ExternalClientLibrary(String)

path to client library

Adds an external client library for use by the multi-version client API. Must be set before setting up the network.

ExternalClientDirectory(String)

path to directory containing client libraries

Searches the specified path for dynamic libraries and adds them to the list of client libraries for use by the multi-version client API. Must be set before setting up the network.

DisableLocalClient

Prevents connections through the local client, allowing only connections through externally loaded client libraries.

ClientThreadsPerVersion(i32)

Number of client threads to be spawned. Each cluster will be serviced by a single client thread.

Spawns multiple worker threads for each version of the client that is loaded. Setting this to a number greater than one implies disable_local_client.

DisableClientStatisticsLogging

Disables logging of client statistics, such as sampled transaction activity.

EnableSlowTaskProfiling

Deprecated

EnableRunLoopProfiling

Enables debugging feature to perform run loop profiling. Requires trace logging to be enabled. WARNING: this feature is not recommended for use in production.

ClientBuggifyEnable

Enable client buggify - will make requests randomly fail (intended for client testing)

ClientBuggifyDisable

Disable client buggify

ClientBuggifySectionActivatedProbability(i32)

probability expressed as a percentage between 0 and 100

Set the probability of a CLIENT_BUGGIFY section being active for the current execution.

ClientBuggifySectionFiredProbability(i32)

probability expressed as a percentage between 0 and 100

Set the probability of an active CLIENT_BUGGIFY section being fired. A section will only fire if it was activated

DistributedClientTracer(String)

Distributed tracer type. Choose from none, log_file, or network_lossy

Set a tracer to run on the client. Should be set to the same value as the tracer set on the server.
