configurations required for CarbonD
| carbon.numberof.preserve.segments | 0 | If the user wants to preserve
some number of segments from being compacted then he can set this property.
Example: carbon.numberof.preserve.segments = 2 then 2 latest segments will
always be excluded from the compaction. No segments will be preserved by
default. |
| carbon.allowed.compaction.days | 0 | Compaction will merge the segments
which are loaded with in the specific number of days configured. Example: If
the configuration is 2, then the segments which are loaded in the time frame of
2 days only will get merged. Segments which are loaded 2 days apart will not be
merged. This is disabled by default. |
| carbon.enable.auto.load.merge | false | To enable compaction while data
loading. |
+|carbon.enable.page.level.reader.in.compaction|true|Enabling page level
reader for compaction reduces the memory usage while compacting more number of
segments. It allows reading only page by page instead of reaing whole blocklet
to memory.|
