|*Property*|*Description*
|nifi.flow.configuration.file*|The location of the flow configuration file (i.e., the file that contains what is currently displayed on the NiFi graph). The default value is `./conf/flow.xml.gz`.
|nifi.flow.configuration.archive.enabled*|Specifies whether NiFi creates a backup copy of the flow automatically when the flow is updated. The default value is `true`.
|nifi.flow.configuration.archive.dir*|The location of the archive directory where backup copies of the flow.xml are saved. The default value is `./conf/archive`. NiFi removes old archive files to limit disk usage based on archived file lifespan, total size, and number of files, as specified with `nifi.flow.configuration.archive.max.time`, `max.storage` and `max.count` properties respectively. If none of these limitation for archiving is specified, NiFi uses default condition, that is "30 days" for max.time and "500 MB" for max.storage. +

This cleanup mechanism takes into account only automatically created archived flow.xml files. If there are other files or directories in this archive directory, NiFi will ignore them. Automatically created archives have filename with ISO 8601 format timestamp prefix followed by '_<original-filename>'. That is <year><month><day>T<hour><minute><second>+<timezone offset>_<original filename>. For example, `20160706T160719+0900_flow.xml.gz`. NiFi checks filenames when it cleans archive directory. If you would like to keep a particular archive in this directory without worrying about NiFi deleting it, you can do so by copying it with a different filename pattern.
|nifi.flow.configuration.archive.max.time*|The lifespan of archived flow.xml files. NiFi will delete expired archive files when it updates flow.xml if this property is specified. Expiration is determined based on current system time and the last modified timestamp of an archived flow.xml. If no archive limitation is specified in nifi.properties, NiFi removes archives older than "30 days".
|nifi.flow.configuration.archive.max.storage*|The total data size allowed for the archived flow.xml files. NiFi will delete the oldest archive files until the total archived file size becomes less than this configuration value, if this property is specified. If no archive limitation is specified in nifi.properties, NiFi uses "500 MB" for this.
|nifi.flow.configuration.archive.max.time*|The lifespan of archived flow.xml files. NiFi will delete expired archive files when it updates flow.xml if this property is specified. Expiration is determined based on current system time and the last modified timestamp of an archived flow.xml. If no archive limitation is specified in nifi.properties, NiFi removes archives older than `30 days`.
|nifi.flow.configuration.archive.max.storage*|The total data size allowed for the archived flow.xml files. NiFi will delete the oldest archive files until the total archived file size becomes less than this configuration value, if this property is specified. If no archive limitation is specified in nifi.properties, NiFi uses `500 MB` for this.
|nifi.flow.configuration.archive.max.count*|The number of archive files allowed. NiFi will delete the oldest archive files so that only N latest archives can be kept, if this property is specified.
|nifi.flowcontroller.autoResumeState|Indicates whether -upon restart- the components on the NiFi graph should return to their last state. The default value is `true`.
|nifi.flowcontroller.graceful.shutdown.period|Indicates the shutdown period. The default value is `10 secs`.
|nifi.flowservice.writedelay.interval|When many changes are made to the flow.xml, this property specifies how long to wait before writing out the changes, so as to batch the changes into a single write. The default value is `500 ms`.
|nifi.administrative.yield.duration|If a component allows an unexpected exception to escape, it is considered a bug. As a result, the framework will pause (or administratively yield) the component for this amount of time. This is done so that the component does not use up massive amounts of system resources, since it is known to have problems in the existing state. The default value is `30 secs`.
|nifi.bored.yield.duration|When a component has no work to do (i.e., is "bored"), this is the amount of time it will wait before checking to see if it has new data to work on. This way, it does not use up CPU resources by checking for new work too often. When setting this property, be aware that it could add extra latency for components that do not constantly have work to do, as once they go into this "bored" state, they will wait this amount of time before checking for more work. The default value is `10 ms`.
|nifi.queue.backpressure.count|When drawing a new connection between two components, this is the default value for that connection's back pressure object threshold. The default is 10000 and the value must be an integer.
|nifi.queue.backpressure.size|When drawing a new connection between two components, this is the default value for that connection's back pressure data size threshold. The default is 1 GB and the value must be a data size including the unit of measure.

|nifi.authorizer.configuration.file*|This is the location of the file that specifies how authorizers are defined. The default value is `./conf/authorizers.xml`.
|nifi.login.identity.provider.configuration.file*|This is the location of the file that specifies how username/password authentication is performed. This file is
only considered if `nifi.security.user.login.identity.provider` is configured with a provider identifier. The default value is `./conf/login-identity-providers.xml`.

|*Property*|*Description*
|nifi.content.repository.implementation|The Content Repository implementation. The default value is `org.apache.nifi.controller.repository.FileSystemRepository` and should only be changed with caution. To store flowfile content in memory instead of on disk (at the risk of data loss in the event of power/machine failure), set this property to `org.apache.nifi.controller.repository.VolatileContentRepository`.
