| 12:38 | Estimate row sizes for tables and indices and use those estimates during query planning. Enhance the index_info pragma to show the estimated row sizes and to show the estimated row size for the main table as well. Allow an alternative row size estimate to be specified in the sqlite_stat1 table. check-in: d27b88b8 user: drh tags: trunk | |
|
2013-10-09
| ||
| 19:07 | Make sure the correct printf format is used for type tRowcnt regardless of whether 32-bit or 64-bit row counts are specified at compile-time. Closed-Leaf check-in: e97d7d30 user: drh tags: row-size-est | |
|
2013-10-08
| ||
| 23:16 | Move a conditional inside of an #ifdef in order to make all branches reachable regardless of compile-time options used. check-in: f7cc30d4 user: drh tags: row-size-est | |
| 22:25 | Fix test cases for the new information in PRAGMA index_list. check-in: dd03be10 user: drh tags: row-size-est | |
| 20:42 | Rollback some of the previous changes in the branch such that the estimated row sizes are now only used as a tie-breaker for index scans. check-in: 65553ff3 user: drh tags: row-size-est | |
| 20:01 | Use #ifdefs to omit unused code in the columnType() routine depending on compile-time options. check-in: 3fd5e332 user: drh tags: row-size-est | |
| 18:40 | Further refinement of the idea of multiplying run-time cost estimates by the estimated row size. check-in: 18bd6ba9 user: drh tags: row-size-est | |
|
2013-10-07
| ||
| 21:49 | Fix compilation issue with MSVC. check-in: 36d64dc3 user: mistachkin tags: trunk | |
| 17:32 | Multiply all cursor step cost estimates by the estimated size of the row in bytes, in order to get the query planner ot make use of estimated row sizes. This check-in uses magic numbers in a few places (for example, estimates of the size of output rows) and needs lots of refinement. Consider this a proof-of-concept only. check-in: cb34cfe5 user: drh tags: row-size-est | |
| 16:53 | Try to remember statistics from ANALYZE using LogEst instead of u64. Leaf check-in: 8e78557a user: drh tags: log-stats | |
| 10:48 | Merge bug fixes from trunk. check-in: 1d7b2dc0 user: drh tags: row-size-est | |

|
2013-10-06
| ||
| 22:52 | Remove an incorrect debugging assert() that was accidently added during the STAT4 enhancement. check-in: 2bb7f74b user: drh tags: trunk | |
| 22:12 | Accept the sz=N parameter on table-only lines of sqlite_stat1. check-in: e9e932aa user: drh tags: row-size-est | |
|
2013-10-05
| ||
| 20:18 | Fix an issue in the test8.c test module that arises because of the change to PRAGMA index_list(). Remove an unused local variable. check-in: 029430c5 user: drh tags: row-size-est | |
| 19:18 | Completely remove the iScanRatio field. The PRAGMA index_list(TABLE) command shows the estimated row size in the forth column. It also generates a row for the table with an index name of NULL. The query planner still does not take row size estimates into account - that is the next step. check-in: 8b4aa0c7 user: drh tags: row-size-est | |
| 18:32 | Improvements to the LogEst command-line tool used to convert between ordinary numbers and the LogEst representation. check-in: 5252aeb6 user: drh tags: row-size-est | |
| 18:16 | Begin an experimental refactoring to estimate the average number of bytes in table and index rows and to use that information in query planner. Begin by renaming WhereCost to LogEst and making that type and its conversion routines available outside of where.c. check-in: 66c4a251 user: drh tags: row-size-est | |
| 02:56 | In the index_list pragma, make sure the "r" column is the same on output as it was on input in the sqlite_stat1 table. Closed-Leaf check-in: de78250a user: drh tags: index-scan-rate | |
|
2013-10-04
| ||
| 20:39 | Merge trunk changes. check-in: c6ac80ed user: drh tags: index-scan-rate | |
| 18:29 | Further refinements of the index scanning speed logic. check-in: e5d9371d user: drh tags: index-scan-rate | |
| 18:17 | If an "INSERT INTO ... SELECT" can use the xfer optimization, pass the OPFLAG_BULKCSR hint to btree cursors used to update indices. This results in a tighter key packing. check-in: 087af29e user: dan tags: trunk | |
| 15:58 | Fix test cases so that they work when the query planner uses index size estimates to determine whether or not to try an covering index scan. check-in: 2f394de8 user: drh tags: index-scan-rate | |
| 15:30 | Improved estimates of the relative speed of index scans based on declared datatypes of columns in the table. Add "r" column to PRAGMA index_info, showing the estimated relative scan rate. check-in: 07462bb6 user: drh tags: index-scan-rate | |
| 02:36 | Progress toward using the iScanRatio information on indices. Many tests are still failing. check-in: 6c352edb user: drh tags: index-scan-rate | |
| 00:00 | Make sure the count(*) optimization works correctly even when partial indices are present. Ticket [a5c8ed66cae]. check-in: 9f2f4c0a user: drh tags: trunk | |
|
2013-10-03
| ||
| 20:41 | Have FTS take advantage of "docid<?" constraints when they are present. Extend the FTS "incremental doclist" optimization so that it is used for tokens within multi-token phrases. check-in: baf8ce59 user: dan tags: trunk | |
| 20:28 | Merge latest trunk changes. Closed-Leaf check-in: 24aa20da user: dan tags: fts4-docid-range-constraints | |
| 19:27 | Allow FTS4 multi-token phrases to use a combination of in-memory and incrementally loaded doclists. This allows phrases to (partially) benefit from incremental doclists without disabling the deferred token optimization. check-in: f6819c5f user: dan tags: fts4-docid-range-constraints | |
| 19:21 | Experimental branch allowing different postulated scan rates for each index. check-in: d59d97b0 user: drh tags: index-scan-rate | |
| 15:39 | The sqlite3FixInit() routine cannot fail. So change the return type from "int" to "void". check-in: 500c5932 user: drh tags: trunk | |
| 14:08 | Rework the PRAGMA implementation to only call sqlite3ReadSchema() from a single place, based on a flag in the pragma table, rather than separately from each case which needs the schema. check-in: 8338232a user: drh tags: trunk | |
| 12:29 | Return an error if an attempt is made to create a trigger with an SQL variable embedded within it. If such a variable reference is found within a trigger definition loaded from the sqlite_master table, silently replace it with a NULL. check-in: f35f6ae3 user: dan tags: trunk | |
| 11:27 | Remove unnecessary memset() calls from test code. check-in: eec3187b user: drh tags: trunk | |
|
2013-10-02

| 20:46 | In the lemon parser generator, change all hashes to unsigned to avoid potential problems with signed integer overflow. check-in: 8d399a03 user: drh tags: trunk | |
| 08:04 | Add a test to check that the new multi-token phrase optimization is actually helping. check-in: bc3a2ed5 user: dan tags: fts4-docid-range-constraints | |
|
2013-10-01
| ||
| 20:29 | Bring some file format comments in btreeInt.h up to date. check-in: 012d54d0 user: drh tags: trunk | |
| 20:10 | Merge trunk changes with this branch. check-in: 65d9c6fa user: dan tags: fts4-docid-range-constraints | |
| 20:02 | Allow multi-token phrases to load doclists from the database incrementally. This allows queries that feature such phrases to benefit from the "docid<?" optimization. check-in: ea543f08 user: dan tags: fts4-docid-range-constraints | |
| 19:36 | Fix comments in the fast_vacuum.c demonstration program. check-in: e0db7b38 user: drh tags: trunk | |
| 19:02 | Add the "fast_vacuum.c" demonstration program to the tool/ subdirectgory. check-in: 2b60320d user: drh tags: trunk | |
| 15:30 | Change the ".dump" command in the command-line shell so that it COMMITs if there are database corruption errors but invokes ROLLBACK on any other kind of error. check-in: 47323463 user: drh tags: trunk | |

| 12:40 | Updates to the sqlite3_analyzer utility: Change the names of some labels, especially change "Fragmentation" to "Non-sequential pages". Revise the computation of non-sequential pages so that it ignores itercalated non-leaf pages (overflow and index pages). check-in: 3e5c7771 user: drh tags: trunk | |
|
2013-09-26
