Nicolas Carlot updated KAFKA-9880:
----------------------------------
Description:
When restoring a non empty RocksDB state store, if it is customized to use
FIFOCompaction, the following exception is thrown:
{code:java}
//
org.apache.kafka.streams.errors.ProcessorStateException: Error while range
compacting during restoring store merge_store

{code}
Compaction is configured through an implementation of RocksDBConfigSetter. The
exception si gone as soon as I remove:
{code:java}
//
CompactionOptionsFIFO fifoOptions = new CompactionOptionsFIFO();
fifoOptions.setMaxTableFilesSize(maxSize);
fifoOptions.setAllowCompaction(true);
options.setCompactionOptionsFIFO(fifoOptions);
options.setCompactionStyle(CompactionStyle.FIFO);
{code}
Bulk loading works fine when the store is non-existent / empty. This occurs
only when there are a minimum amount of data in it. I guess it happens when the
amount SST layers is increased.
I'm currently using a forked version of Kafka 2.4.1 customizing the
RocksDBStore class with this modification as a work around:
{code:java}
//
public void toggleDbForBulkLoading() {
try {
db.compactRange(columnFamily, true, 1, 0);
} catch (final RocksDBException e) {
try {
if (columnFamily.getDescriptor().getOptions().compactionStyle() !=
CompactionStyle.FIFO) {
throw new ProcessorStateException("Error while range compacting
during restoring store " + name, e);
}
else {
log.warn("Compaction of store " + name + " for bulk loading failed.
Will continue without compacted store, which will be slower.", e);
}
} catch (RocksDBException e1) {
throw new ProcessorStateException("Error while range compacting
during restoring store " + name, e);
}
}
}
{code}
I'm not very proud of this workaround, but it suits my use cases well.
