.SH "DESCRIPTION"
|
|
.PP
|
|
\fBndb_index_stat\fR
|
|
provides per\-fragment statistical information about indexes on
|
|
NDB
|
|
tables\&. This includes cache version and age, number of index entries per partition, and memory consumption by indexes\&.
|
|
Usage.PP
|
|
To obtain basic index statistics about a given
|
|
NDB
|
|
table, invoke
|
|
\fBndb_index_stat\fR
|
|
as shown here, with the name of the table as the first argument and the name of the database containing this table specified immediately following it, using the
|
|
\fB\-\-database\fR
|
|
(\fB\-d\fR) option:
|
|
.sp
|
|
.if n \{\
|
|
.RS 4
|
|
.\}
|
|
.nf
|
|
ndb_index_stat \fItable\fR \-d \fIdatabase\fR
|
|
.fi
|
|
.if n \{\
|
|
.RE
|
|
.\}
|
|
.PP
|
|
In this example, we use
|
|
\fBndb_index_stat\fR
|
|
to obtain such information about an
|
|
NDB
|
|
table named
|
|
mytable
|
|
in the
|
|
test
|
|
database:
|
|
.sp
|
|
.if n \{\
|
|
.RS 4
|
|
.\}
|
|
.nf
|
|
shell> \fBndb_index_stat \-d test mytable\fR
|
|
table:City index:PRIMARY fragCount:2
|
|
sampleVersion:3 loadTime:1399585986 sampleCount:1994 keyBytes:7976
|
|
query cache: valid:1 sampleCount:1994 totalBytes:27916
|
|
times in ms: save: 7\&.133 sort: 1\&.974 sort per sample: 0\&.000
|
|
NDBT_ProgramExit: 0 \- OK
|
|
.fi
|
|
.if n \{\
|
|
.RE
|
|
.\}
|
|
.PP
|
|
sampleVersion
|
|
is the version number of the cache from which the statistics data is taken\&. Running
|
|
\fBndb_index_stat\fR
|
|
with the
|
|
\fB\-\-update\fR
|
|
option causes sampleVersion to be incremented\&.
|
|
.PP
|
|
loadTime
|
|
shows when the cache was last updated\&. This is expressed as seconds since the Unix Epoch\&.
|
|
.PP
|
|
sampleCount
|
|
is the number of index entries found per partition\&. You can estimate the total number of entries by multiplying this by the number of fragments (shown as
|
|
fragCount)\&.
|
|
.PP
|
|
sampleCount
|
|
can be compared with the cardinality of
|
|
SHOW INDEX
|
|
or
|
|
INFORMATION_SCHEMA\&.STATISTICS, although the latter two provide a view of the table as a whole, while
|
|
\fBndb_index_stat\fR
|
|
provides a per\-fragment average\&.
|
|
.PP
|
|
keyBytes
|
|
is the number of bytes used by the index\&. In this example, the primary key is an integer, which requires four bytes for each index, so
|
|
keyBytes
|
|
can be calculated in this case as shown here:
|
|
.sp
|
|
.if n \{\
|
|
.RS 4
|
|
.\}
|
|
.nf
|
|
keyBytes = sampleCount * (4 bytes per index) = 1994 * 4 = 7976
|
|
.fi
|
|
.if n \{\
|
|
.RE
|
|
.\}
|
|
.PP
|
|
This information can also be obtained using the corresponding column definitions from
|
|
INFORMATION_SCHEMA\&.COLUMNS
|
|
(this requires a MySQL Server and a MySQL client application)\&.
|
|
.PP
|
|
totalBytes
|
|
is the total memory consumed by all indexes on the table, in bytes\&.
|
|
.PP
|
|
Timings shown in the preceding examples are specific to each invocation of
|
|
\fBndb_index_stat\fR\&.
|
|
.PP
|
|
The
|
|
\fB\-\-verbose\fR
|
|
option provides some additional output, as shown here:
|
|
.sp
|
|
.if n \{\
|
|
.RS 4
|
|
.\}
|
|
.nf
|
|

|

.PP
|
|
If the only output from the program is
|
|
NDBT_ProgramExit: 0 \- OK, this may indicate that no statistics yet exist\&. To force them to be created (or updated if they already exist), invoke
|
|
\fBndb_index_stat\fR
|
|
with the
|
|
\fB\-\-update\fR
|
|
option, or execute
|
|
ANALYZE TABLE
|
|
on the table in the
|
|
\fBmysql\fR
|
|
client\&.
|
|
Options.PP
|

The following table includes options that are specific to the NDB Cluster
|
|
\fBndb_index_stat\fR

utility\&. Additional descriptions are listed following the table\&. For options common to most NDB Cluster programs (including
