stack commented on HBASE-8155:
------------------------------
So, we should make it so you could do either. Wouldn't we have to do
record-based compression if we want replication to work (my guess is that it
would get messed up if block-based was enabled). Would have to have big
records for this to have an effect -- > 10k or so? Seems like a small change
for big win to me.
> Allow Record Compression for HLogs

> Key: HBASE-8155
> URL: https://issues.apache.org/jira/browse/HBASE-8155
> Project: HBase
> Issue Type: New Feature
> Components: regionserver, wal
> Reporter: Nicolas Spiegelberg
> Priority: Trivial
>
> While HBASE-4608 allows for Key-intelligent log compression & custom
> extensions, Hadoop already allows for native compression support with
> SequenceFile. We should allow the user to enable this functionality through
> the config. Besides backwards compatibility & existing stabilized code,
> allowing users to enable record-level WAL support will allow support value
> compression.
