stack reassigned HBASE-775:
---------------------------
Assignee: Billy Pearson
Billy, you think that you could have a go at this one? Doesn't look too hard.
Add a new configuration into hbase-default.xml named something like
hbase.hstore.compaction.max In the HStore constructor, you would read its
setting and save it off to a data member. See
'hbase.hstore.compactionThreshold' for an example. Then you'd add something
around line #785 in HStore where you'd only compact the
hbase.hstore.compaction.max amount.
Also, checkout HBASE-64. So much has changed since that issue was originally
filed but there are a load of your ideas in there about how we should do
compactions. Perhaps distill out the good stuff into new, more pointed issues?
