[jira] [Created] (HBASE-12016) Reduce number of versions in Meta table.

Andrey Stepachev created HBASE-12016:
----------------------------------------

             Summary: Reduce number of versions in Meta table.
                 Key: HBASE-12016
                 URL: https://issues.apache.org/jira/browse/HBASE-12016
             Project: HBase
          Issue Type: Improvement
    Affects Versions: 1.0.0, 2.0.0
            Reporter: Andrey Stepachev
            Assignee: Andrey Stepachev
            Priority: Minor

Currently meta keeps up to 10 versions of each KV. 
For big metas it leads to substantial memory overhead and scan slowdowns.
(see https://issues.apache.org/jira/browse/HBASE-11165 )

Need to keep reasonable number of versions (suggested value is 3). 
Even better make that configurable.

During modifyTable, if a MOB CF is removed from a table, the corresponding mob data also should get removed.

Hey all,

Currently, the namespaces are not being explicitly stated while displaying the user tables. This will
help in decoupling the table names and their corresponding namespaces.

Currently code accessed meta table name via HTableDescriptor.META_TABLEDESC.getTableName(), but we
have TableName.META_TABLE_NAME already. It is better to use from one place.

          Components: Client, regionserver
    Affects Versions: 0.89-fb
            Reporter: Alex Goltman
             Fix For: 0.89-fb

Allow assigning priority to Get, Put, MultiPut, and MultiAction, in preparation for later QoS tasks.
Current policy regarding MultiPuts and MultiAction sent by client after batching operations - the Multi
operation's priority will be equal to the one of the contained operations' priority. If the client would
like to send mixed Puts/Gets with different priorities he should call flushCommits() in between. The
logic behind this is the server will have to process all the operations in the batch operation, and thus
they all must have the same priority.
