There's no point in indexing the file if it hasn't been synced to
disk. Any attempts to index the file will fail if the file still has an
open data block.
All modules now declare a name for the module. This is name is added as a
prefix to all messages logged by a module. The prefix should help
determine which part of the system logs a message.
Currently, when the avrorouter finishes reading a binlog file or when a
certain number of rows or transactions is reached, it will flush all
tables to disk. This is quite slow as events can easily be written faster
into the binlog than they can be processed by avrorouter.
A solution to this would be to only sync the tables (close the Avro block)
instead of flushing them to disk. This would allow more efficient
processing of the files while still retaining the safe shutdown that
flushing offers.
