[jira] [Created] (HBASE-5674) add support in HBase to overwrite hbase timestamp to a version number during major compaction
add support in HBase to overwrite hbase timestamp to a version number during major compaction - Key: HBASE-5674 URL: https://issues.apache.org/jira/browse/HBASE-5674 Project: HBase Issue Type: Improvement Reporter: He Yongqiang Assignee: He Yongqiang Right now, a millisecond-level timestamp is attached to every record. In our case, we only need a version number (mostly it will be just zero etc). A millisecond timestamp is too heavy to carry. We should add support to overwrite it to zero during major compaction. KVs before major compaction will remain using system timestamp. And this should be configurable, so that we should not mess up if the hbase timestamp is specified by application. -- This message is automatically generated by JIRA.

[jira] [Created] (HBASE-5521) Move compression/decompression to an encoder specific encoding context
Move compression/decompression to an encoder specific encoding context -- Key: HBASE-5521 URL: https://issues.apache.org/jira/browse/HBASE-5521 Project: HBase Issue Type: Improvement Reporter: He Yongqiang As part of working on HBASE-5313, we want to add a new columnar encoder/decoder. It makes sense to move compression to be part of encoder/decoder: 1) a scanner for a columnar encoded block can do lazy decompression to a specific part of a key value object 2) avoid an extra bytes copy from encoder to hblock-writer. If there is no encoder specified for a writer, the HBlock.Writer will use a default compression-context to do something very similar to today's code. -- This message is automatically generated by JIRA.

[jira] [Created] (HBASE-5457) add inline index in data block for data which are not clustered together
add inline index in data block for data which are not clustered together Key: HBASE-5457 URL: https://issues.apache.org/jira/browse/HBASE-5457 Project: HBase Issue Type: New Feature Reporter: He Yongqiang As we are go through our data schema, and we found we have one large column family which is just duplicating data from another column family and is just a re-org of the data to cluster data in a different way than the original column family in order to serve another type of queries efficiently. If we compare this second column family with similar situation in mysql, it is like an index in mysql. So if we can add inline block index on required columns, the second column family then is not needed. -- This message is automatically generated by JIRA.
