Hello,
I created yesterday an HTable with 2 CF specifying the TTL for 5 an 10
min respectively.
Inserted 2 datas (one in each column)
And hoped that my values desapear passed a certain amount of time.
This never happend ...
This morning I keep hope that major_compaction once a days withdraw my
expired datas ...
Disapointed :
hbase(main):004:0> describe 'ttltest'

test1

1 row(s) in 0.1280 seconds
Is TTL usable to purge expired values (even the last ones) ?
Best regards,
