| <div class="block">See if we should actually SEEK or rather just SKIP to the next Cell (see HBASE-13109). |
| ScanQueryMatcher may issue SEEK hints, such as seek to next column, next row, or seek to an |
| arbitrary seek key. This method decides whether a seek is the most efficient _actual_ way to |
| get us to the requested cell (SEEKs are more expensive than SKIP, SKIP, SKIP inside the |
| current, loaded block). It does this by looking at the next indexed key of the current HFile. |
| This key is then compared with the _SEEK_ key, where a SEEK key is an artificial 'last possible |
| key on the row' (only in here, we avoid actually creating a SEEK key; in the compare we work |
| with the current Cell but compare as though it were a seek key; see down in |
| matcher.compareKeyForNextRow, etc). If the compare gets us onto the next block we *_SEEK, |
| otherwise we just SKIP to the next requested cell. |
| <p> |
| Other notes: |
| <ul> |
| <li>Rows can straddle block boundaries</li> |
| <li>Versions of columns can straddle block boundaries (i.e. column C1 at T1 might be in a |
| different block than column C1 at T2)</li> |
| <li>We want to SKIP if the chance is high that we'll find the desired Cell after a few |
| SKIPs...</li> |
| <li>We want to SEEK when the chance is high that we'll be able to seek past many Cells, |
| especially if we know we need to go to the next block.</li> |
| </ul> |
| <p> |
| A good proxy (best effort) to determine whether SKIP is better than SEEK is whether we'll |
| likely end up seeking to the next block (or past the next block) to get our next column. |
| Example: |
| |
| <pre> |
| | BLOCK 1 | BLOCK 2 | |
| | r1/c1, r1/c2, r1/c3 | r1/c4, r1/c5, r2/c1 | |
| ^ ^ |
| | | |
| Next Index Key SEEK_NEXT_ROW (before r2/c1) |
| |
| |
| | BLOCK 1 | BLOCK 2 | |
| | r1/c1/t5, r1/c1/t4, r1/c1/t3 | r1/c1/t2, r1/c1/T1, r1/c2/T3 | |
| ^ ^ |
| | | |
| Next Index Key SEEK_NEXT_COL |
| </pre> |
| |
| Now imagine we want columns c1 and c3 (see first diagram above), the 'Next Index Key' of r1/c4 |
| is > r1/c3 so we should seek to get to the c1 on the next row, r2. In second case, say we only |
| want one version of c1, after we have it, a SEEK_COL will be issued to get to c2. Looking at |
| the 'Next Index Key', it would land us in the next block, so we should SEEK. In other scenarios |
| where the SEEK will not land us in the next block, it is very likely better to issues a series |
| of SKIPs.</div> |
