|Field|Type|Description|Required|

|type|String|This should always be 'realtime'.|no|
|maxRowsInMemory|Integer|The number of rows to aggregate before persisting. This number is the post-aggregation rows, so it is not equivalent to the number of input events, but the number of aggregated rows that those events result in. This is used to manage the required JVM heap size. Maximum heap memory usage for indexing scales with maxRowsInMemory * (2 + maxPendingPersists).|no (default == 5 million)|

|windowPeriod|ISO 8601 Period String|The amount of lag time to allow events. This is configured with a 10 minute window, meaning that any event more than 10 minutes ago will be thrown away and not included in the segment generated by the realtime server.|no (default == PT10m)|
|intermediatePersistPeriod|ISO8601 Period String|The period that determines the rate at which intermediate persists occur. These persists determine how often commits happen against the incoming realtime stream. If the realtime data loading process is interrupted at time T, it should be restarted to re-read data that arrived at T minus this period.|no (default == PT10m)|
|basePersistDirectory|String|The directory to put things that need persistence. The plumber is responsible for the actual intermediate persists and this tells it where to store those persists.|no (default == java tmp dir)|
