Date Wed, 09 Jan 2013 02:14:14 GMT

Enis Soztutar commented on HBASE-7519:
--------------------------------------

bq. It will be even great if we can dynamically tune/choose a proper one.
Sergey is doing the basic blocks of managing global/per-table/per-cf configuration in HBASE-7236.
After that, we can start to think about HBASE-5678. However, even without the dynamic config,
we should be able to tune the parameters by rolling reopen for the regions.

> The level compaction algorithm may help HBase for some use cases, for example, read heavy
loads (especially, just one version is used), relative small key space updated frequently.
