void	testMatch_ExpiredExplicit() Verify that ScanQueryMatcher only skips expired KeyValue instances and does not exit early from the row (skipping later non-expired KeyValues).

void	testMatchWhenFilterReturnsIncludeAndSeekNextRow()
void	testMergeFilterResponseCase1() Here is the unit test for UserScanQueryMatcher#mergeFilterResponse, when the number of cells exceed the versions requested in scan, we should return SEEK_NEXT_COL, but if current match code is INCLUDE_AND_SEEK_NEXT_ROW, we can optimize to choose the max step between SEEK_NEXT_COL and INCLUDE_AND_SEEK_NEXT_ROW, which is SEEK_NEXT_ROW.
void	testMergeFilterResponseCase2() Here is the unit test for UserScanQueryMatcher#mergeFilterResponse: the match code may be changed to SEEK_NEXT_COL or INCLUDE_AND_SEEK_NEXT_COL after merging with filterResponse, even if the passed match code is neither SEEK_NEXT_COL nor INCLUDE_AND_SEEK_NEXT_COL.
void	testNeverIncludeFakeCell() This is a cryptic test.

Method Detail

testNeverIncludeFakeCell

public void testNeverIncludeFakeCell()
                              throws IOException

This is a cryptic test. It is checking that we don't include a fake cell, one that has a timestamp of HConstants.OLDEST_TIMESTAMP. See HBASE-16074 for background.

Throws:

IOException

testMatchExplicitColumns

public void testMatchExplicitColumns()
                              throws IOException

Throws:

IOException

testMatch_Wildcard

public void testMatch_Wildcard()
                        throws IOException

Throws:

IOException

testMatch_ExpiredExplicit

public void testMatch_ExpiredExplicit()
                               throws IOException

Verify that ScanQueryMatcher only skips expired KeyValue instances and does not exit early from the row (skipping later non-expired KeyValues). This version mimics a Get with explicitly specified column qualifiers.

Throws:

IOException

testMatch_ExpiredWildcard

public void testMatch_ExpiredWildcard()
                               throws IOException

Verify that ScanQueryMatcher only skips expired KeyValue instances and does not exit early from the row (skipping later non-expired KeyValues). This version mimics a Get with wildcard-inferred column qualifiers.

Throws:

IOException

testMatchWhenFilterReturnsIncludeAndSeekNextRow

public void testMatchWhenFilterReturnsIncludeAndSeekNextRow()
                                                     throws IOException

Throws:

IOException

testMergeFilterResponseCase1

public void testMergeFilterResponseCase1()
                                  throws IOException

Here is the unit test for UserScanQueryMatcher#mergeFilterResponse, when the number of cells exceed the versions requested in scan, we should return SEEK_NEXT_COL, but if current match code is INCLUDE_AND_SEEK_NEXT_ROW, we can optimize to choose the max step between SEEK_NEXT_COL and INCLUDE_AND_SEEK_NEXT_ROW, which is SEEK_NEXT_ROW.

Throws:

IOException

testMergeFilterResponseCase2

public void testMergeFilterResponseCase2()
                                  throws Exception

Here is the unit test for UserScanQueryMatcher#mergeFilterResponse: the match code may be changed to SEEK_NEXT_COL or INCLUDE_AND_SEEK_NEXT_COL after merging with filterResponse, even if the passed match code is neither SEEK_NEXT_COL nor INCLUDE_AND_SEEK_NEXT_COL. In that case, we need to make sure that the ColumnTracker has been switched to the next column.
An effective test way is: we only need to check the cell from getKeyForNextColumn(). because that as long as the UserScanQueryMatcher returns SEEK_NEXT_COL or INCLUDE_AND_SEEK_NEXT_COL, UserScanQueryMatcher#getKeyForNextColumn should return an cell whose column is larger than the current cell's.

Throws:

Exception
