A compression or archive format to which log files should be converted when they are closed. Default value: zip.

The name of the file used by the file appender. Default value: ${ataccama.path.log}/{self.microservice_id.module_name}_{self.microservice_id.microservice_name}.log.

Indicates how often the current log file should be closed and a new one started. Default value: 4 days.

The minimum severity level starting from which logged messages are sent to the sink. Default value: INFO.

Controls retrying of gRPC and graphQL communication attempts. The property determines when retrying stops. By default, retrying stops after 6 attempts in total, out of which 5 are retries. Default value: {"max_attempt_number": 6}.

Controls retrying of gRPC and graphQL communication attempts. The property determines which approach is used to stop retrying. For more information, see the Tenacity API Reference, Stop Functions section. Default value: stop_after_attempt.

Controls retrying of gRPC and graphQL communication attempts. The property is used to calculate the duration of waiting periods between retries. For more information about how waiting periods between unsuccessful attempts are managed, see the Tenacity API Reference, Wait Functions section. Default value: {"multiplier": 0.16, "exp_base": 2}.

Controls retrying of gRPC and graphQL communication attempts. The property determines which approach is used when waiting. For more information about how waiting periods between unsuccessful attempts are managed, see the Tenacity API Reference, Wait Functions section. Default value: wait_exponential.

Sets for how many seconds the microservice waits after requesting health information about its dependencies, for example, when the Recommender waits for the Neighbors or the Autocomplete waits for MMM. For more information, see the Requests Developer Interface Documentation, section about the timeout parameter. Default value: 5.

Defines the behavior of the microservice while it waits on a dependency before starting. Keyword arguments (kwargs) are the arguments used to construct an instance of the specified wait type. In this case, the keyword argument sets the duration of waiting intervals. Default value: {"wait": 2.5}.

Defines the behavior of the microservice while it waits on a dependency before starting. Currently, the microservice either waits to receive information about the health of the dependency or the database readiness (typically, this means waiting for the database to start and for MMM to create the tables needed). The property defines how waiting periods are managed between unsuccessful attempts to verify the readiness of the dependency. For a list of other available wait types, see the Tenacity API Reference, Wait Functions section. Default value: wait_fixed.

Limits the size of messages that the gRPC client can process. Default value: 1GB. Accepted units: B (bytes), KB (kilobytes), MB (megabytes), GB (gigabytes), TB (terabytes). If no unit is specified, KB is used.

Limits the size of messages that the gRPC server can process. Default value: 1GB. Accepted units: B (bytes), KB (kilobytes), MB (megabytes), GB (gigabytes), TB (terabytes). If no unit is specified, KB is used.

The value of the HTTP Strict-Transport-Security (HSTS) response header. Used only when HTTPS is enabled. Informs browsers that the resource should only be accessed using the HTTPS protocol. Default value: max-age=31536000; includeSubDomains; preload.

An alternative way of overriding the number of parallel threads spawned by low-level calculations that are used by machine learning algorithms. If the value is set to 0, all CPU cores run without hyper-threads. If the value is not set (null), other properties are not overridden. Relies on the static OpenBLAS API and might be ignored depending on the compilation options for the OpenBLAS library. When this property is set, OpenBLAS gives it higher priority compared to ataccama.one.apyc.parallelism.omp. This is intended only for exceptional cases and should not be used otherwise. Default value: null.

The number of parallel threads or processes spawned by high-level machine learning algorithms with explicit job management. If the value is set to 0, all CPU cores run without hyper-threads. If the value is not set (null), the library default settings are applied. Use this option together with ataccama.one.apyc.parallelism.omp. For more information, see the Sizing Guidelines. Default value: 1.

The number of parallel threads spawned by low-level calculations that are used by high-level machine learning algorithms. If the value is set to 0, all CPU cores run without hyper-threads. If the value is not set (null), the library default settings are applied. The property relies on the static OpenBLAS API and OpenMP API, which have a lower overhead than the dynamic API used by the property ataccama.one.apyc.parallelism.threads. When this property is set, the OpenBLAS library gives it lower priority compared to ataccama.one.apyc.parallelism.blas. Several low-level libraries other than OpenBLAS and LAPACK, as well as libraries that use OpenMP, respect this option as well. Use this option together with ataccama.one.apyc.parallelism.jobs. For more information, see the Sizing Guidelines. Default value: 1.

The dynamic API is intended only for exceptional cases and should not be used otherwise. Default value: null.

Points to the keystore containing the symmetric key that is used to decrypt properties with I context, for example: file:${ataccama.path.etc}/key-store.pkcs12. Default value: null.

The password for the keystore. Used if the keystore is encrypted. To use an empty password, set the value to an empty string (""). Default value: null.

The single-line file containing the password for the keystore. When reading the file, UTF-8 encoding is assumed. Used if the keystore is encrypted. If specified, the property overrides the value of internal.encryption.key-store-password. Default value: null.

The type of the keystore. Possible types are PKCS12, JKS, and JCEKS. Default value: null.

Points to the keystore containing the symmetric key that is used to decrypt properties with P context, for example, file:${ataccama.path.etc}/key-store.pkcs12. Default value: null.

The password for the keystore. Used if the keystore is encrypted. To use an empty password, set the value to an empty string (""). Default value: null.

The single-line file containing the password for the keystore. When reading the file, UTF-8 encoding is assumed. Used if the keystore is encrypted. If specified, the property overrides the value of properties.encryption.key-store-password. Default value: null.

The type of the keystore. Possible types are PKCS12, JKS, and JCEKS. Default value: null.

Sets the SQLAlchemy engine options, such as the maximum length of identifiers used in the database. For more information, see the Engine Configuration, section Engine Creation API, Parameters. Default value: {"max_identifier_length": 128}.

Defines how often the microservice polls the database for changes. Expressed in seconds. Default value: 1.

The maximum number of fingerprints that can be present in the index used for searching neighbors. Once this value is reached, the microservice shuts down when trying to add new attributes. If the number of attributes in the database, including the deleted ones, exceeds the limit on startup, the microservice waits in the Not ready state indefinitely or until the number of attributes is reduced to this value or lower. Default value: 1000000.
