Configure the File JSON Output adapter by specifying values for the ESP connector, formatter, and transporter modules in the adapter configuration file.
Parameter | Description |
---|---|
Log4jProperty |
Type: string (Optional) Specify the path to the log4j.properties logging file you wish to use. The default value is $ESP_HOME/adapters/framework/config/log4j.properties. |
Parameter | Description |
---|---|
Module |
(Required) Section containing all information for this module. It contains a type attribute for specifying the module type. For example, espconnector. |
InstanceName |
Type: string (Required) Specify the instance name of the specific module you wish to use. For example, MyInputTransporter. |
Name |
Type: string (Required) The name of the module as defined in the modulesdefine.xml file. For example, <TransporterType>InputTransporter. |
Next |
Type: string (Required) Specify the instance name of the module that follows this one. |
Parameters | (Required) Section containing the EspSubscriberParameters parameter. |
EspSubscriberParameters |
(Required) Section containing parameters for the ESP subscriber. |
ProjectName |
Type: string (Required if running adapter in standalone mode; optional if running in managed mode) Specifies the unique project tag of the ESP project to which the adapter is connected. For example, EspProject2. This is the same project tag that you specify later in the adapter configuration file in the Name parameter of the Event Stream Processor (EspProjects) parameters section. If you are starting the adapter with the ESP project to which it is attached (running the adapter in managed mode), you do not need to set this property as the adapter automatically detects the project name. |
StreamName |
Type: string (Required if running adapter in standalone mode; optional if running in managed mode) Name of the ESP stream from which the adapter subscribes to data. If you are starting the adapter with the ESP project to which it is attached (running the adapter in managed mode), you do not need to set this property as the adapter automatically detects the stream name. |
Parameter | Description |
---|---|
Module |
(Required) Section containing all information for this module. It contains a type attribute for specifying the module type. For example, formatter. |
InstanceName |
Type: string (Required) Specify the instance name of the specific module you wish to use. For example, MyInputTransporter. |
Name |
Type: string (Required) The name of the module as defined in the modulesdefine.xml file. For example, <TransporterType>InputTransporter. |
Next |
Type: string (Required) Specify the instance name of the module that follows this one. |
Parameters |
(Required) Section containing the EsptoJsonStreamFormatterParameters parameter. |
EsptoJsonStreamFormatterParameters |
(Required) Section containing the ESP to JSON Stream formatter parameters. |
ColsMapping |
(Required) Section containing the Column parameter. |
Column |
Type: complextype (Required) Specify which columns of an ESP row you wish to map to JSON data. These values are matched by a pattern path expression. For example, [<Column>JSONPath expression</Column>]+. The first <Column/> is mapped to the first column of an ESP row, the second <Column/> is mapped to the second column of an ESP row, and so on. |
DateFormat |
Type: string (Advanced) The format string for date values. For example, yyyy-MM-dd'T'HH:mm:ss. |
TimestampFormat |
Type: string (Advanced) Format string for timestamp values. For example, yyyy-MM-dd'T'HH:mm:ss.SSS. |
Parameter | Description |
---|---|
Module |
(Required) Section containing all information for this module. It contains a type attribute for specifying the module type. For example, transporter. |
InstanceName |
Type: string (Required) Specify the instance name of the specific module you wish to use. For example, MyInputTransporter. |
Name |
Type: string (Required) The name of the module as defined in the modulesdefine.xml file. For example, <TransporterType>InputTransporter. |
Parameters |
(Required) Section containing the FileOutputTransporterParameters parameter. |
FileOutputTransporterParameters |
(Required) Section containing the parameters for the File Output transporter. |
Dir |
Type: string (Required) Specify the absolute path to the data files that you want the adapter to write to. For example, <username>/<foldername>. The default value is ".", meaning the current directory in which the adapter is running. Use a forward slash for both UNIX and Windows paths. |
File |
Type: string (Required) Specify the file to which you want the adapter to write. |
AccessMode |
Type: string (Required) Specify an access mode. The adapter supports two modes:
|
AppendMode |
Type: boolean (Optional) If set to true, the adapter appends the data into the existing file. If set to false, the adapter overwrites existing content in the file. Default value is false. |
Event Stream Processor parameters configure communication between Event Stream Processor and the File JSON Output adapter.
Parameter | Description |
---|---|
EspProjects |
Section containing parameters for connecting to Event Stream Processor. |
EspProject |
Section containing the Name and Uri parameters. Specifies information for the ESP project to which the adapter is connected. |
Name |
Type: string (Required) Specifies the unique project tag of the ESP project which the espconnector (publisher/subscriber) module references. |
Uri |
Type: string (Required) Specifies the total project URI to connect to the Event Stream Processor cluster. For example, esp://localhost:19011/ws1/p1. |
Security |
Section containing all the authentication parameters below. Specifies details for the authentication method used for Event Stream Processor. |
User |
Type: string (Required) Specifies the user name required to log in to Event Stream Processor (see AuthType). No default value. |
Password |
Type: string (Required) Specifies the password required to log in to Event Stream Processor (see espAuthType). Includes an "encrypted" attribute indicating whether the Password value is encrypted. Default value is false. If set to true, the password value is decrypted using RSAKeyStore and RSAKeyStorePassword. |
AuthType |
Type: string (Required) Specifies method used to authenticate to the
Event Stream Processor. Valid values are:
If the adapter is operated as a Studio plug-in, AuthType is overridden by the Authentication Mode Studio start-up parameter. |
RSAKeyStore |
Type: string (Dependent required) Specifies the location of the RSA keystore, and decrypts the password value. Required if AuthType is set to server_rsa, or the encrypted attribute for Password is set to true, or both. |
RSAKeyStorePassword |
Type:string (Dependent required) Specifies the keystore password, and decrypts the password value. Required if AuthType is set to server_rsa, or the encrypted attribute for Password is set to true, or both. |

KerberosTicketCache |
Type: string (Dependent required) Specifies the location of the Kerberos ticket cache file. Required if AuthType is set to kerberos. |
