Matteo Bertozzi updated HBASE-6353:
-----------------------------------
Description:
h6. hbase shell with snapshot commands
* snapshot <snapshot name> <table name>
** Take a snapshot of the specified name with the specified name
* restore_snapshot <snapshot name>
** Restore specified snapshot on the original table
* clone_snapshot <snapshot name> <table name>
** Create a new table based on the snapshot content
* list_snapshots [filter]
** Show the list of snapshots taken
* delete_snapshot <snapshot name>
** Remove a specified snapshot
* rename_snapshot <snapshot name> <new snapshot name>
** Rename a snapshot to a new name
h6. Restore Table
Given a "snapshot name" restore override the original table with the snapshot
content.
Before restoring a new snapshot of the table is taken, just to avoid bad
situations.
This allows a full and quick rollback to a previous snapshot.
h6. Clone from Snapshot
Given a "snapshot name" a new table is created with the content of the
specified snapshot.
This operation allows:
* To have an old version of the table in parallel with the current one.
** Look at snapshot side-by-side with the "current" before making the decision
whether to roll back or not
* To Add/Remove data from this table without affecting the original one or the
snapshot.
* To Restore only "individual items" (only some small range of data was lost
from "current")
** MR job that scan the cloned table and update the data in the original one.
(Partial restore of the data)
h6. Open points
* Add snapshot type option on take snapshot command (global, timestamp)?

h6. hbase shell with snapshot commands
* snapshot <snapshot name> <table name>
** Take a snapshot of the specified name with the specified name
* restore_snapshot <snapshot name>
** Restore specified snapshot on the original table
* mount_snapshot <snapshot name> <table name> [readonly]
** Load the snapshot data as specified table (optional readonly flag)
* list_snapshots [filter]
** Show a list of snapshots
* delete_snapshot <snapshot name>
** Remove a specified snapshot
h6. Restore Table
Given a "snapshot name" restore override the original table with the snapshot
content.
Before restoring a new snapshot of the table is taken, just to avoid bad
situations.
(If the table is not disabled we can keep serving reads)
This allows a full and quick rollback to a previous snapshot.
h6. Mount Table (Aka Clone Table)
Given a "snapshot name" a new table is created with the content of the
specified snapshot.
This operation allows:
* To have an old version of the table in parallel with the current one.
** Look at snapshot side-by-side with the "current" before making the decision
whether to roll back or not
* To Restore only "individual items" (only some small range of data was lost
from "current")
** MR job that scan the cloned table and update the data in the original one.
(Partial restore of the data)
* if the table is not marked as read-only
** To Add/Remove data from this table without affecting the original one or
the snapshot.
h6. Open points
* Add snapshot type option on take snapshot command (global, timestamp)?
* Keep separate the "restore" from "mount"?
