auto_high_volume vs hardset to 10GB ?

[the_wolverine]

Is setting auto_high_volume the same as setting bucket size to 10GB? Or, does auto_high_volume give a variable bucket size? I'm trying to size my indexes and need to know this.

Are there any pros/cons of using one vs. the other?

In 4.2.1, you do not need to account for bucket sizes to figure out how to partition. You can easily set the hot/warm and cold with specific parameters:

[volume:volume_name]
maxVolumeDataSizeMB = <integer>

In general, auto_high_volume works well and you should not be required to perform manual bucket sizing. Review the indexes.conf.spec or example file for more information.

To answer the setting question, "auto_high_volume" sets the size to 10GB on 64-bit, and 1GB on 32-bit systems.
