In Folio app, the following tags may be configured on the projMeta record of the project to tune some low-level options:

  • steadyState: a number such as 3min which determines how long to wait after startup before the project is considered steady state. The default is 1min.

  • evalTimeout: a number such as 2min which determines how long to allow a REST call to evaluate before raising a TimeoutErr. The default is 1min. Note expressions evaluated in the context of a job or the spark engine have an unlimited timeout.

  • strTagLimit (number): because tags with a string value are stored in memory, the system enforces a character limit to avoid excessive memory usage. The default is 10,000 chars. You might need to set this value higher if you have very long string values such as the src tag of a function.

  • autoIndexLimit: determines how many queries must be executed against a tag before indexing the tag. Default is 100.

  • disableDiscovery: turns off multicast discovery of the project.

The user must restart for changed to take effect. The current tuning options listed above may be all be checked using the Folio App under the Debug tab. You can also configure most of these parameters on a host level using etc/proj/config.props file.



To change the axon function limit of 10,000 characters, the user must change the value of the strTagLimit tag.
