General Channel properties are configured on the Summary Tab within the Edit Channel View and include:
- Unique ID, name, and description.
- Links to Code Template Libraries: These let the channel know which custom functions are available in specific JavaScript contexts.
- Links to Library Resources: These let the channel know which custom Java classes are available in specific connectors and/or JavaScript contexts.
- Deploy/Start Dependencies: These determine which channels are dependent on this one, and also which channels are dependencies for this one. This way you can have some channels deploy and start before others.
- Attachment Handler: This allows you to extract pieces of any incoming message and store them separately. As a message processes through a channel, multiple copies of it will be held in memory at once (for the raw / transformed / encoded versions of a message). Attachments are stored only once, so by using them you can greatly reduce your channels' memory footprint.
- Message Storage Settings: These determine how much message data to store / retain and whether to encrypt content. These settings affect the performance of the channel and also determine whether you can enable persistent queuing on your connectors.
- Message Pruning Settings: These determine how long to keep message data around before automatically removing it with the Data Pruner. You can also decide to archive data out to a file somewhere before pruning it.
- Custom Metadata Columns: These allow you to extract pieces of data from your message and store them in dedicated columns in the internal Mirth® Connect database. You can then view and search on them in the Message Browser.
