Connector/J (JDBC) Reference
these rewritten statements only works when the
entire batch includes INSERT statements.
Use newer result set row unpacking code that
skips a copy from network buffers to a MySQL
packet instance and instead reads directly into the
result set row data buffers.
Should the driver use a per-connection cache of
character set information queried from the server
when necessary, or use a built-in static mapping
that is more efficient, but isn't aware of custom
character sets or character sets implemented after
the release of the JDBC driver?
Use internal String->Date/Time/Timestamp
conversion routines to avoid excessive object
creation?
Use internal String->Integer conversion routines to
avoid excessive object creation?
Always use the character encoding routines built
into the JVM, rather than using lookup tables for
single-byte character sets?
Use newer, optimized non-blocking, buffered input
stream when reading from the server?
Definition
The name of a class that implements
"com.mysql.jdbc.log.Log" that will be
used to log messages to. (default is
"com.mysql.jdbc.log.StandardLogger", which logs
to STDERR)
Should the driver gather performance metrics,
and report them via the configured logger every
'reportMetricsIntervalMillis' milliseconds?
Trace queries and their execution/fetch times to
the configured logger (true/false) defaults to 'false'
Deprecated, use 'profileSQL' instead. Trace
queries and their execution/fetch times on
STDERR (true/false) defaults to 'false'
If 'gatherPerfMetrics' is enabled, how often should
they be logged (in ms)?
Controls the maximum length/size of a query that
will get logged when profiling or tracing
The maximum number of packets to retain when
'enablePacketDebug' is true
If 'logSlowQueries' is enabled, how long should a
query (in ms) before it is logged as 'slow'?
If 'useNanosForElapsedTime' is set to true, and
this property is set to a non-zero value, the driver
will use this threshold (in nanosecond units) to
determine if a query was slow.
