Method Detail

testWithColumnCountGetFilter

public void testWithColumnCountGetFilter()
                                  throws Exception

Throws:

Exception

testFullRowGetDoesNotOverreadWhenRowInsideOneBlock

public void testFullRowGetDoesNotOverreadWhenRowInsideOneBlock()
                                                        throws IOException

Throws:

IOException

testFullRowSpansBlocks

public void testFullRowSpansBlocks()
                            throws IOException

Throws:

IOException

testOptimize

public void testOptimize()
                  throws IOException

Test optimize in StoreScanner. Test that we skip to the next 'block' when we it makes sense reading the block 'index'.

Throws:

IOException

testOptimizeAndGet

public void testOptimizeAndGet()
                        throws IOException

Ensure the optimize Scan method in StoreScanner does not get in the way of a Get doing minimum work... seeking to start of block and then SKIPPING until we find the wanted Cell. This 'simple' scenario mimics case of all Cells fitting inside a single HFileBlock. See HBASE-15392. This test is a little cryptic. Takes a bit of staring to figure what it up to.

Throws:

IOException

testOptimizeAndGetWithFakedNextBlockIndexStart

public void testOptimizeAndGetWithFakedNextBlockIndexStart()
                                                    throws IOException

Ensure that optimize does not cause the Get to do more seeking than required. Optimize (see HBASE-15392) was causing us to seek all Cells in a block when a Get Scan if the next block index/start key was a different row to the current one. A bug. We'd call next too often because we had to exhaust all Cells in the current row making us load the next block just to discard what we read there. This test is a little cryptic. Takes a bit of staring to figure what it up to.

Throws:

IOException
