eff835ffe7 Detect infinite loops using only lower boundaries. 2011-09-26 08:53:22 -06:00

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

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

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

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

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

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

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

968d10ac37 Refactor TableChecksum for NibbleIterator (use only BIT_XOR, return just column list, etc.). 2011-09-10 12:21:00 -06:00
