Overview

LTE (Load to Engine) is an operation that loads properties from disk into the computing engine or memory to optimize query performance. It allows faster access to data, reducing disk I/O.

After a property is LTE-ed, it isn't loaded into memory immediately but when accessed via a query or during a cache warm-up operation. LTE can be performed on custom properties or the system property _id.

When a property is no longer needed for LTE, you can execute the UFE (Unload from Engine) operation to remove it. Even though UFE-ed properties may remain in memory temporarily until they are cleared or evicted, they will not be accessed by queries anymore.

LTE

You can perform LTE for a property using the LTE() statement. The LTE operation runs as a job, you may run show().job(<id?>) afterward to verify the success of the completion.

To perform LTE for node property @member._id:

LTE().node_property(@member._id)

To perform LTE for edge property @transfer.amount:

LTE().edge_property(@transfer.amount)

UFE

You can perform UFE for a property using the UFE() statement.

To perform UFE for node property @member._id:

UFE().node_property(@member._id)

To perform UFE for edge property @transfer.amount:

UFE().edge_property(@transfer.amount)
