Page size in bytes
|

The number of bytes in a single page of the database file.

Usually 1024.

Number of pages in the whole file

Pages that store data
|
||||
|
||||
The number of pages that store data, either as primary B*Tree pages or
|
||||
as overflow pages. The number at the right is the data pages divided by
|
||||
the total number of pages in the file.
|
||||
|
||||
Pages on the freelist
|
||||
|
||||
The number of pages that are not currently in use but are reserved for
|
||||
future use. The percentage at the right is the number of freelist pages
|
||||
divided by the total number of pages in the file.
|
||||
|
||||
Pages of auto-vacuum overhead
|
||||
|
||||
The number of pages that store data used by the database to facilitate
|
||||
auto-vacuum. This is zero for databases that do not support auto-vacuum.
|
||||
|
||||
Number of tables in the database
|
||||
|
||||
The number of tables in the database, including the SQLITE_MASTER table
|
||||
used to store schema information.
|
||||
|
||||
Number of indices
|
||||
|
||||
The total number of indices in the database.
|
||||
|
||||
Number of defined indices
|
||||
|
||||
The number of indices created using an explicit CREATE INDEX statement.
|
||||
|
||||
Number of implied indices
|
||||
|
||||
The number of indices used to implement PRIMARY KEY or UNIQUE constraints
|
||||
on tables.
|
||||
|
||||
Size of the file in bytes
|
||||
|
||||
The total amount of disk space used by the entire database files.
|
||||
|
||||
Bytes of user payload stored
|
||||
|
||||
The total number of bytes of user payload stored in the database. The
|
||||
schema information in the SQLITE_MASTER table is not counted when
|
||||
computing this number. The percentage at the right shows the payload
|
||||
divided by the total file size.
|
||||
|
||||
Percentage of total database
|
||||
|
||||
The amount of the complete database file that is devoted to storing
|
||||
information described by this category.
|
||||
|
||||
Number of entries
|
||||
|
||||
The total number of B-Tree key/value pairs stored under this category.
|
||||
|
||||
Bytes of storage consumed
|
||||
|
||||
The total amount of disk space required to store all B-Tree entries
|
||||
under this category. The is the total number of pages used times
|
||||
the pages size.
|
||||
|
||||
Bytes of payload
|
||||
|
||||
The amount of payload stored under this category. Payload is the data
|
||||
part of table entries and the key part of index entries. The percentage
|
||||
at the right is the bytes of payload divided by the bytes of storage
|
||||
consumed.
|
||||
|
||||
Bytes of metadata
|
||||
|
||||
The amount of formatting and structural information stored in the
|
||||
table or index. Metadata includes the btree page header, the cell pointer
|
||||
array, the size field for each cell, the left child pointer or non-leaf
|
||||
cells, the overflow pointers for overflow cells, and the rowid value for
|
||||
rowid table cells. In other words, metadata is everything that is neither
|
||||
unused space nor content. The record header in the payload is counted as
|
||||
content, not metadata.
|
||||
|
||||
Average payload per entry
|
||||
|
||||
The average amount of payload on each entry. This is just the bytes of
|
||||
payload divided by the number of entries.
|
||||
|
||||
Average unused bytes per entry
|
||||
|
||||
The average amount of free space remaining on all pages under this
|
||||
category on a per-entry basis. This is the number of unused bytes on
|
||||
all pages divided by the number of entries.
|
||||
|
||||
Non-sequential pages
|
||||
|
||||
The number of pages in the table or index that are out of sequence.
|
||||
Many filesystems are optimized for sequential file access so a small
|
||||
number of non-sequential pages might result in faster queries,
|
||||
especially for larger database files that do not fit in the disk cache.
|
||||
Note that after running VACUUM, the root page of each table or index is
|
||||
at the beginning of the database file and all other pages are in a
|
||||
separate part of the database file, resulting in a single non-
|
||||
sequential page.
|
||||
|
||||
Maximum payload per entry
|
||||
|
||||
The largest payload size of any entry.
|
||||
|
||||
Entries that use overflow
|
||||
|
||||
The number of entries that user one or more overflow pages.
|
||||
|
||||
Total pages used
|
||||
|
||||
This is the number of pages used to hold all information in the current
|
||||
category. This is the sum of index, primary, and overflow pages.
|
||||
|
||||
Index pages used
|
||||
|
||||
This is the number of pages in a table B-tree that hold only key (rowid)
|
||||
information and no data.
|
||||
|
||||
Primary pages used
|
||||
|
||||
This is the number of B-tree pages that hold both key and data.
|
||||
|
||||
Overflow pages used
|
||||
|
||||
The total number of overflow pages used for this category.
|
||||
|
||||
Unused bytes on index pages
|
||||
|
||||
The total number of bytes of unused space on all index pages. The
|
||||
percentage at the right is the number of unused bytes divided by the
|
||||
total number of bytes on index pages.
|
||||
|
||||
Unused bytes on primary pages
|
||||
|
||||
The total number of bytes of unused space on all primary pages. The
|
||||
percentage at the right is the number of unused bytes divided by the
|
||||
total number of bytes on primary pages.
|
||||
|
||||
Unused bytes on overflow pages
|
||||
|
||||
The total number of bytes of unused space on all overflow pages. The
|
||||
percentage at the right is the number of unused bytes divided by the
|
||||
total number of bytes on overflow pages.
|
||||
|
||||
Unused bytes on all pages
|
||||
|
||||
The total number of bytes of unused space on all primary and overflow
|
||||
pages. The percentage at the right is the number of unused bytes
|
||||
divided by the total number of bytes.
