------------------------------------
Summary: Low hanging checksum improvements
Key: HBASE-8323
URL: https://issues.apache.org/jira/browse/HBASE-8323
Project: HBase
Issue Type: Improvement
Reporter: Enis Soztutar
Over at Hadoop land, [~tlipcon] had done some improvements for checksums, a
native implementation for CRC32C (HADOOP-7445) and bulk verify of checksums
(HADOOP-7444).
In HBase, we can do
- Also develop a bulk verify API. Regardless of
hbase.hstore.bytes.per.checksum we always want to verify of the whole checksum
for the hfile block.
- Enable NativeCrc32 to be used as a checksum algo. It is not clear how much
gain we can expect over pure java CRC32.
Though, longer term we should focus on convincing hdfs guys for inline
checksums (HDFS-2699)
