Changelog
Evolutions
- [CONJ-675] permit multiple alternative authentication methods for the same user (future MariaDB 10.4 feature)
- {CONJ-678] permit indication of truststore/keystore type (JKS/PKCS12), then not relying on java default type
- [CONJ-378] GSSAPI: client can provide SPN
- [CONJ-667] Support MYSQL_TYPE_JSON datatype
- [CONJ-652] faster results buffering socket available
- [CONJ-659] improve text performance reading date/time/timestamp resultset
- [CONJ-670] ability to Refresh SSL certificate
New options:
| Option | Description |
|---|---|
| useReadAheadInput | use a buffered inputSteam that read socket available data. Default: true |
| keyStoreType | indicate key store type (JKS/PKCS12). default is null, then using java default type. |
| trustStoreType | indicate trust store type (JKS/PKCS12). default is null, then using java default type |
| servicePrincipalName | when using GSSAPI authentication, SPN (Service Principal Name) use the server SPN information. When set, connector will use this value, ignoring server information |
| includeInnodbStatusInDeadlockExceptions | add "SHOW ENGINE INNODB STATUS" result to exception trace when having a deadlock exception. Default: false |
| includeThreadDumpInDeadlockExceptions | add thread dump to exception trace when having a deadlock exception. Default: false |
CONJ-642 disable the option "useBulkStmts" by default
Using useBulkStmts permit faster batch, but cause one major issue: Batch return -1 = SUCCESS_NO_INFO
Different option uses this information for optimistic update, and cannot confirm if update succeeds or not.
This option still makes sense, since for big batch is way faster, but will not be activated by default.
