memmapThreshold property
Maximum size (in kilobytes) of vectors to store in-memory per segment. Segments larger than this threshold will be stored as read-only memmapped file.
Memmap storage is disabled by default, to enable it, set this threshold to a reasonable value.
To disable memmap storage, set this to 0.
Note: 1Kb = 1 vector of size 256
Implementation
@$pb.TagNumber(5)
$fixnum.Int64 get memmapThreshold => $_getI64(4);
