Subject [jira] [Commented] (HBASE-18232) Add variable size chunks to the MSLAB
Date Mon, 26 Jun 2017 09:47:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18232?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16062850#comment-16062850

Anastasia Braginsky commented on HBASE-18232:

# Add a method isVariableSize() to the Chunk interface, which is going to calculate the boolean
answer based on the sizes comparison
# Add new interface to ChunkCreator so a new Chunk of a specified size is created and returned
to the user.
# After creation, the variable size chunk is going to be managed as regular chunk, however
upon release() request its ByteBuffer is going to be deallocated immediately.
# Usage: while creating CellChunkMap if found any cell allocated on heap and bigger than a
chunk, allocate a variable size chunk and copy the cell there.
