Overview
A Publisher facilitates the creation of historical outputs from records collected by devices. Each Publisher instance manages its own index marker for device records collected so it doesn't republish or skip records.
...
Following any filter rules, the Publisher operates on batches of records controlled by the index marker that are then processed by the desired output type.
Creating A Publisher
A Publisher can be created using any one of several methods. See Creating Objects.

The Batch Size is not the total number of records to be returned. There are three sets of records that will be returned on one retrieval that may impact the total record count: archive, meters and liquid products.

Query Timeout (Default = 30) Time (in seconds) for database query to time out while loading records to publish.
| Info | ||
|---|---|---|
| ||
Frequent timeouts usually indicate that more data is being requested than the database can process in that amount of time. The query timeout may be increased, but smaller batch sizes run more quickly, more frequently and tend to yield overall faster publisher time. |
