Rakesh R commented on BOOKKEEPER-634:
-------------------------------------
bq.The way that you get whole ledgers into a set and then issues all reads at
the same time is definitely terrible. You should use the LedgerIterator and do
it iterator by iterator, and you have to bind the outstanding metadata reads
and updates to not overwhelm metadata store (zookeeper).
The reason for getting all the ledgers to a set and processing is to print the
execution progress
{code}
BookKeeperAdmin.java
if (TimeUnit.SECONDS.convert(System.nanoTime() - lastReport,
TimeUnit.NANOSECONDS) > 5) {
System.out.println("Total ledgers " + ledgers.size() + ",
renamed " + completedLedgers.size()
+ " pending " + (ledgers.size() -
completedLedgers.size()));
lastReport = System.nanoTime();
}
{code}
Latest patch is attached to BOOKKEEPER-773.
