Ted Yu commented on HBASE-18294: -------------------------------- How would the off-heap threshold be determined ? Is it related to the value given by -XX:MaxDirectMemorySize parameter ? > Flush is based on data size instead of heap size > ------------------------------------------------ > > Key: HBASE-18294 > URL: https://issues.apache.org/jira/browse/HBASE-18294 > Project: HBase > Issue Type: Bug > Reporter: Eshcar Hillel > Assignee: Eshcar Hillel > > A region is flushed if its memory component exceed a threshold (default size > is 128MB). > A flush policy decides whether to flush a store by comparing the size of the > store to another threshold (that can be configured with > hbase.hregion.percolumnfamilyflush.size.lower.bound). > Currently the implementation (in both cases) compares the data size > (key-value only) to the threshold where it should compare the heap size > (which includes index size, and metadata). -- This message was sent by Atlassian JIRA (v6.4.14#64029)
