06b99e987c Don't checksum 1=1 on master if table on slave is too large. 2011-11-17 13:15:26 -07:00
Daniel Nichter
7b8736c1f5 Use SELECT * instead of SELECT COUNT(*) to avoid 'Select tables optimized away'. Make _get_row_estimate() "public". 2011-11-17 12:15:21 -07:00

07420ff78e Don't crash on empty tables with --chunk-size-limit=0. Don't crash trying to print MySQL warning. Finish updating (all the important) tests. 2011-10-15 17:47:56 -06:00

964bb094a0 Get row estimate from NibbleIterator. Use user's index over MySQL's index when --where is given. 2011-10-13 09:23:53 -06:00
Daniel Nichter
28fa7d62c2 Support --where in NibbleIterator. If --where, prefer index that MySQL wants to use. Keep SHOW TABLE STATUS from SchemaIterator and re-use it in NibbleIterator (avoids double execution). 2011-10-13 08:49:32 -06:00
Daniel Nichter

25882d49e7 Resume for SchemaIterator. Use only next_lb; don't need first_lb in NibbleIterator. 2011-09-27 13:06:24 -06:00
Daniel Nichter
04eca15150 Add next_boundaries callback. 2011-09-27 10:23:09 -06:00
Daniel Nichter
83bbe45187 Simplify NibbleIterator callbacks. Pass args to init callback so caller can check ub_sth. 2011-09-27 08:21:34 -06:00
Daniel Nichter
c9e8444166 Handle one-chunk tables. Chunk tables w/o indexes if they're small enough. Check index for every chunk. Check chunk size if ub and next_lb are equal. 2011-09-26 11:38:35 -06:00
Daniel Nichter
10e31c1b63 Fix NibbleIterator::_can_nibble_once(). Add boundaries() and one_nibble(), remove unused _check_index_usage(). 2011-09-26 10:23:42 -06:00

eff835ffe7 Detect infinite loops using only lower boundaries. 2011-09-26 08:53:22 -06:00
Daniel Nichter
9f3e05691c Detect infinite loops. Use best non-unique index. Disable chunk size limit if chunk index is unique. 2011-09-23 17:33:23 -06:00
Daniel Nichter
07cb6010a2 More repl table columns: chunk_time, chunk_index, lower_boundary, and upper_boundary (those two replace boundaries). 2011-09-23 10:13:57 -06:00
Daniel Nichter
f6fb8b44bd Decompose ReplicaLagLimiter into ReplicaLagWaiter and WeightedAvgRate. Don't use OptionParser in NibbleIterator; use chunk_size arg instead. 2011-09-21 11:19:49 -06:00
Daniel Nichter
30dc37e3a5 Debug-print initial chunk size. 2011-09-20 11:51:40 -06:00
Daniel Nichter
be9337a202 Pass NibbleIterator obj to callbacks. 2011-09-20 10:05:37 -06:00
Daniel Nichter
26b99b20ad Use weighted exp avg instead of moving avg for ReplicaLagLimiter::update(). Use "LIMIT ?, 2" for ub_sql/sth in NibbleIterator. 2011-09-19 11:41:41 -06:00
Daniel Nichter
006b93ddf9 Create ReplicaLagLimiter. Replace --max-lag, --check-interval, and --check-slave-lag with --replica-lag and --replica-lag-dsn. Use TableParser::get_table_status() in NibbleItertor. Eval SHOW TABLE STATUS. Auto-add "n" (name) part to parsed DSNs. 2011-09-16 17:35:40 -06:00

Daniel Nichter
8ce093655f Add dms arg, remove before_row callback, pass some args to callbacks, get next boundary if no rows (so exec_nibble callback can skip nibbles). 2011-09-11 10:22:40 -06:00
Daniel Nichter
84f7c47ff4 Rename new TableChecksum to RowChecksum and revert TableChecksum to r108. This will avoid completely break TableSync*.pm and pt-table-sync. 2011-09-10 13:46:55 -06:00
