Sijie Guo commented on BOOKKEEPER-120:
--------------------------------------
Why there is two 'ledger_dirs' settings in 'Bookie configuraiton' section? Is
it duplicated?
{code}
+p. Directory Bookkeeper outputs its write ahead log, ideally in a dedicated
device. The default value is "/tmp/bk-txn".
+
+* ledger_dirs
+
+p. Directory Bookkeeper outputs ledger snapshots could define multiple
directories to store snapshots, comma separated. For example:
/tmp/bk1-data,/tmp/bk2-data
+
+* ledger_dirs
+
+p. Ideally ledger dirs and journal dir are each in a differet device, which
reduce the contention between random i/o and sequential write. It is possible
to run with a single disk, but performance will be significantly lower.
+
{code}
BTW, BOOKKEEPER-119 is trying to standardize configuration keys in bookkeeper.
