Endpoint Properties

Name	Type	Default	Description
`accountName`	string		name of the azure account
`fileSystemName`	string		name of filesystem to be used
`clientId`	string		client id for azure account
`close`	boolean		Whether or not a file changed event raised indicates completion (true) or modification (false)
`closeStreamAfterRead`	boolean		check for closing stream after read
`credentialType`	object	`CLIENT_SECRET`	Determines the credential strategy to adopt
`dataCount`	integer		count number of bytes to download
`dataLakeServiceClient`	object		service client of data lake
`directoryName`	string		directory of the file to be handled in component
`downloadLinkExpiration`	integer		download link expiration time
`expression`	string		expression for queryInputStream
`fileDir`	string		directory of file to do operations in the local system
`fileName`	string		name of file to be handled in component
`fileOffset`	integer		offset position in file for different operations
`maxResults`	integer		maximum number of results to show at a time
`maxRetryRequests`	integer		no of retries to a given request
`openOptions`	object		set open options for creating file
`path`	string		path in azure data lake for operations
`permission`	string		permission string for the file
`position`	integer		This parameter allows the caller to upload data in parallel and control the order in which it is appended to the file.
`recursive`	boolean		recursively include all paths
`regex`	string		regular expression for matching file names
`retainUncommitedData`	boolean		Whether or not uncommitted data is to be retained after the operation
`serviceClient`	object		data lake service client for azure storage data lake
`sharedKeyCredential`	object		shared key credential for azure data lake gen2
`tenantId`	string		tenant id for azure account
`timeout`	object		Timeout for operation
`umask`	string		umask permission for file
`userPrincipalNameReturned`	boolean		whether or not to use upn
`sendEmptyMessageWhenIdle`	boolean	`false`	If the polling consumer did not poll any files, you can enable this option to send an empty message (no body) instead.
`bridgeErrorHandler`	boolean	`false`	Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions (if possible) occurred while the Camel consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. Important: This is only possible if the 3rd party component allows Camel to be alerted if an exception was thrown. Some components handle this internally only, and therefore bridgeErrorHandler is not possible. In other situations we may improve the Camel component to hook into the 3rd party component and make this possible for future releases. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.
`exceptionHandler`	object		To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored.
`exchangePattern`	object		Sets the exchange pattern when the consumer creates an exchange.
`pollStrategy`	object		A pluggable org.apache.camel.PollingConsumerPollingStrategy allowing you to provide your custom implementation to control error handling usually occurred during the poll operation before an Exchange have been created and being routed in Camel.
`operation`	object	`listFileSystem`	operation to be performed
`lazyStartProducer`	boolean	`false`	Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel's routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.
`backoffErrorThreshold`	integer		The number of subsequent error polls (failed due some error) that should happen before the backoffMultipler should kick-in.
`backoffIdleThreshold`	integer		The number of subsequent idle polls that should happen before the backoffMultipler should kick-in.
`backoffMultiplier`	integer		To let the scheduled polling consumer backoff if there has been a number of subsequent idles/errors in a row. The multiplier is then the number of polls that will be skipped before the next actual attempt is happening again. When this option is in use then backoffIdleThreshold and/or backoffErrorThreshold must also be configured.
`delay`	integer	`500`	Milliseconds before the next poll.
`greedy`	boolean	`false`	If greedy is enabled, then the ScheduledPollConsumer will run immediately again, if the previous run polled 1 or more messages.
`initialDelay`	integer	`1000`	Milliseconds before the first poll starts.
`repeatCount`	integer	`0`	Specifies a maximum limit of number of fires. So if you set it to 1, the scheduler will only fire once. If you set it to 5, it will only fire five times. A value of zero or negative means fire forever.
`runLoggingLevel`	object	`TRACE`	The consumer logs a start/complete log line when it polls. This option allows you to configure the logging level for that.
`scheduledExecutorService`	object		Allows for configuring a custom/shared thread pool to use for the consumer. By default each consumer has its own single threaded thread pool.
`scheduler`	object	`none`	To use a cron scheduler from either camel-spring or camel-quartz component. Use value spring or quartz for built in scheduler
`schedulerProperties`	object		To configure additional properties when using a custom scheduler or any of the Quartz, Spring based scheduler.
`startScheduler`	boolean	`true`	Whether the scheduler should be auto started.
`timeUnit`	object	`MILLISECONDS`	Time unit for initialDelay and delay options.
`useFixedDelay`	boolean	`true`	Controls if fixed delay or fixed rate is used. See ScheduledExecutorService in JDK for details.
`accountKey`	string		account key for authentication
`clientSecret`	string		client secret for azure account
`clientSecretCredential`	object		client secret credential for authentication
`sasCredential`	object		SAS token credential
`sasSignature`	string		SAS token signature
