NFS-Ganesha will support SEEK over NFSv4 in the near future, posisbly with the upcoming nfs-ganesha 2.4. +### Compound operations +*Notes for users:* +This feature is being introduced with the intention of improving performance +for file operations on a glusterfs volume. A framework for combining two or +more file operations is provided which will help in reducing the network round +trips made for certain fops. This reduces latency of those fops and provides +better performance than before. + +*Limitations:* +Only very few and specific sets of operations can be compounded at this time. +There is no interface in libgfapi for creating compound operations yet. + +### Geo-replication for Sharded Volumes +*Notes for users:* +With Sharding support, Geo-replication detects small sharded files and syncs to +the slave(s) instead of syncing big files. This enables Geo-rep to sync files +from the master volume to the slave volume(s) more efficiently. + +*Limitations:* +If Sharding is enabled at the master volume then it should be enabled at slave +volume as well. + ### Tiering aware Geo-replication *Notes for users:* Tiering moves files between hot/cold tier bricks.
