FlowFile Repository

The FlowFile repository keeps track of the attributes and current state of each FlowFile in the system. By default, this repository is installed in the same root installation directory as all the other repositories; however, it is advisable to configure it on a separate drive if available.

PropertyDescription
partitionsThe number of partitions. The default value is 256.
checkpoint intervalThe FlowFile Repository checkpoint interval. The default value is 2 mins.
always syncIf set to true, any change to the repository will be synchronized to the disk, meaning that NiFi will ask the operating system not to cache the information. This is very expensive and can significantly reduce NiFi performance. However, if it is false, there could be the potential for data loss if either there is a sudden power loss or the operating system crashes. The default value is false.
