(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. |
Parameters |
(Required) Section containing the EspPublisherParameters parameter. |
EspPublisherParameters |
(Required) Section containing parameters for the ESP publisher. |
ProjectName |
Type: string (Required if running adapter in standalone mode; optional if running in managed mode) Name 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 to which the adapter publishes 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. |
MaxPubPoolSize |
Type: positive integer (Optional) Specifies the maximum size of the record pool. Record pooling, also referred to as block or batch publishing, allows for faster publication since there is less overall resource cost in publishing multiple records together compared to publishing records individually. Block publishing (record pooling or batch publishing) is disabled if this value is set to 1. The default value is 256. |
MaxPubPoolTime |
Type: positive integer (Optional) Specifies the maximum period of time, in milliseconds, for which records are pooled before being published. If not set, pooling time is unlimited and the pooling strategy is governed by maxPubPoolSize. No default value. |
UseTransactions |
Type: boolean (Optional) If set to true, pooled messages are published to Event Stream Processor in transactions. If set to false, they are published in envelopes. Default value is false. |
SafeOps |
Type: boolean (Advanced) Converts the opcodes INSERT and UPDATE to UPSERT, and converts DELETE to SAFEDELETE. The default value is false. |
SkipDels |
Type: boolean (Advanced) Skips the rows with opcodes DELETE or SAFEDELETE. The default value is false. |

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. |
