Description

clear-all can be implemented with empty byte-array as begin and 255 as the end parameter. This can be helpful where we want to wipe all the keys similar to FLUSHALL in Redis. Similar thing can be done to implement get-all using get-range to return all the keys in the database.

Reference: https://forums.foundationdb.org/t/how-to-clear-all-keys-in-foundationdb-using-java/351/2

This is not implemented as part of any official API but I thought it will be a handy wrapper. Feel free to close this if it's irrelevant.

Contributor guide

Research direction
Implement clear all by using an empty byte array as the begin key and 255 as the end key for the range deletion. Implement get all by using get range with empty begin and 255 end to return all keys. Refer to the FoundationDB forum link for guidance.
