> Implement stateless scanner for Stargate
> ----------------------------------------
>
> Key: HBASE-9343
> URL: https://issues.apache.org/jira/browse/HBASE-9343
> Project: HBase
> Issue Type: Improvement
> Components: REST
> Affects Versions: 0.94.11
> Reporter: Vandana Ayyalasomayajula
> Assignee: Vandana Ayyalasomayajula
> Priority: Minor
> Attachments: HBASE-9343_94.00.patch, HBASE-9343_94.01.patch,
> HBASE-9343_trunk.00.patch, HBASE-9343_trunk.01.patch,
> HBASE-9343_trunk.01.patch, HBASE-9343_trunk.02.patch
>
>
> The current scanner implementation for scanner stores state and hence not
> very suitable for REST server failure scenarios. The current JIRA proposes to
> implement a stateless scanner. In the first version of the patch, a new
> resource class "ScanResource" has been added and all the scan parameters will
> be specified as query params.
> The following are the scan parameters
> startrow - The start row for the scan.
> endrow - The end row for the scan.
> columns - The columns to scan.
> starttime, endtime - To only retrieve columns within a specific range of
> version timestamps,both start and end time must be specified.
> maxversions - To limit the number of versions of each column to be returned.
> batchsize - To limit the maximum number of values returned for each call to
> next().
> limit - The number of rows to return in the scan operation.
> More on start row, end row and limit parameters.
> 1. If start row, end row and limit not specified, then the whole table will
> be scanned.
> 2. If start row and limit (say N) is specified, then the scan operation will
> return N rows from the start row specified.
> 3. If only limit parameter is specified, then the scan operation will return
> N rows from the start of the table.
> 4. If limit and end row are specified, then the scan operation will return N
> rows from start of table till the end row. If the end row is
> reached before N rows ( say M and M < N ), then M rows will be returned to
> the user.
> 5. If start row, end row and limit (say N ) are specified and N < number
> of rows between start row and end row, then N rows from start row
> will be returned to the user. If N > (number of rows between start row and
> end row (say M), then M number of rows will be returned to the
> user.
