On December 26, 2017, TiDB 1.0.5 is released with the following updates:
TiDB
- Add the max value for the current Auto_Increment ID in the
Show Create Table
statement. - Fix a potential goroutine leak.
- Support outputting slow queries into a separate file.
- Load the
TimeZone
variable from TiKV when creating a new session. - Support the schema state check so that the
Show Create Table
andAnalyze
statements process the public table/index only. - The
set transaction read only
should affect thetx_read_only
variable. - Clean up incremental statistic data when rolling back.
- Fix the issue of missing index length in the
Show Create Table
statement.
PD
- Fix the issue that the leaders stop balancing under some circumstances.
- Fix potential panic during bootstrapping.
TiKV
- Fix the issue that it is slow to get the CPU ID using the
get_cpuid
function. - Support the
dynamic-level-bytes
parameter to improve the space collection situation.
To upgrade from 1.0.4 to 1.0.5, follow the rolling upgrade order of PD -> TiKV -> TiDB.
