Class SXSSFWorkbook

java.lang.Object
  org.apache.poi.xssf.streaming.SXSSFWorkbook

All Implemented Interfaces:: java.io.Closeable, java.lang.Iterable<Sheet>, Workbook

Direct Known Subclasses:: SXSSFWorkbookWithCustomZipEntrySource

public class SXSSFWorkbook
extends java.lang.Object
implements Workbook
extends java.lang.Object
implements Workbook

Streaming version of XSSFWorkbook implementing the "BigGridDemo" strategy. This allows to write very large files without running out of memory as only a configurable portion of the rows are kept in memory at any one time. You can provide a template workbook which is used as basis for the written data. See https://poi.apache.org/spreadsheet/how-to.html#sxssf for details. Please note that there are still things that still may consume a large amount of memory based on which features you are using, e.g. merged regions, comments, ... are still only stored in memory and thus may require a lot of memory if used extensively. SXSSFWorkbook defaults to using inline strings instead of a shared strings table. This is very efficient, since no document content needs to be kept in memory, but is also known to produce documents that are incompatible with some clients. With shared strings enabled all unique strings in the document has to be kept in memory. Depending on your document content this could use a lot more resources than with shared strings disabled. Carefully review your memory budget and compatibility needs before deciding whether to enable shared strings or not.

Field Detail

DEFAULT_WINDOW_SIZE

public static final int DEFAULT_WINDOW_SIZE

Specifies how many rows can be accessed at most via SXSSFSheet.getRow(int). When a new node is created via SXSSFSheet.createRow(int) and the total number of unflushed records would exceed the specified value, then the row with the lowest index value is flushed and cannot be accessed via SXSSFSheet.getRow(int) anymore.

See Also:: Constant Field Values

Constructor Detail

SXSSFWorkbook

public SXSSFWorkbook()

Construct a new workbook with default row window size

SXSSFWorkbook

public SXSSFWorkbook(XSSFWorkbook workbook)

Construct a workbook from a template.

There are three use-cases to use SXSSFWorkbook(XSSFWorkbook) :

Append new sheets to existing workbooks. You can open existing workbook from a file or create on the fly with XSSF.
Append rows to existing sheets. The row number MUST be greater than max(rownum) in the template sheet.
Use existing workbook as a template and re-use global objects such as cell styles, formats, images, etc.

All three use cases can work in a combination. What is not supported:

Access initial cells and rows in the template. After constructing SXSSFWorkbook(XSSFWorkbook) all internal windows are empty and SXSSFSheet.getRow(int) and SXSSFRow.getCell(int) return null.
Override existing cells and rows. The API silently allows that but the output file is invalid and Excel cannot read it.

Parameters:: workbook - the template workbook

SXSSFWorkbook

public SXSSFWorkbook(XSSFWorkbook workbook,
                     int rowAccessWindowSize)

Constructs an workbook from an existing workbook.

When a new node is created via SXSSFSheet.createRow(int) and the total number of unflushed records would exceed the specified value, then the row with the lowest index value is flushed and cannot be accessed via SXSSFSheet.getRow(int) anymore.

A value of -1 indicates unlimited access. In this case all records that have not been flushed by a call to flush() are available for random access.

A value of 0 is not allowed because it would flush any newly created row without having a chance to specify any cells.

Parameters:: rowAccessWindowSize - the number of rows that are kept in memory until flushed out, see above.

SXSSFWorkbook

public SXSSFWorkbook(XSSFWorkbook workbook,
                     int rowAccessWindowSize,
                     boolean compressTmpFiles)

Constructs an workbook from an existing workbook.

A value of -1 indicates unlimited access. In this case all records that have not been flushed by a call to flush() are available for random access.

A value of 0 is not allowed because it would flush any newly created row without having a chance to specify any cells.

Parameters:: rowAccessWindowSize - the number of rows that are kept in memory until flushed out, see above.; compressTmpFiles - whether to use gzip compression for temporary files

SXSSFWorkbook

public SXSSFWorkbook(XSSFWorkbook workbook,
                     int rowAccessWindowSize,
                     boolean compressTmpFiles,
                     boolean useSharedStringsTable)

Constructs an workbook from an existing workbook.

A value of -1 indicates unlimited access. In this case all records that have not been flushed by a call to flush() are available for random access.

A value of 0 is not allowed because it would flush any newly created row without having a chance to specify any cells.

Parameters:: workbook - the template workbook; rowAccessWindowSize - the number of rows that are kept in memory until flushed out, see above.; compressTmpFiles - whether to use gzip compression for temporary files; useSharedStringsTable - whether to use a shared strings table

SXSSFWorkbook

public SXSSFWorkbook(int rowAccessWindowSize)

Construct an empty workbook and specify the window for row access.

A value of -1 indicates unlimited access. In this case all records that have not been flushed by a call to flush() are available for random access.

A value of 0 is not allowed because it would flush any newly created row without having a chance to specify any cells.

Parameters:: rowAccessWindowSize - the number of rows that are kept in memory until flushed out, see above.

Method Detail

getRandomAccessWindowSize

public int getRandomAccessWindowSize()

See the constructors for a more detailed description of the sliding window of rows.

Returns:: The number of rows that are kept in memory at once before flushing them out.

isCompressTempFiles

public boolean isCompressTempFiles()

Get whether temp files should be compressed.

Returns:: whether to compress temp files

setCompressTempFiles

public void setCompressTempFiles(boolean compress)

Set whether temp files should be compressed.

SXSSF writes sheet data in temporary files (a temp file per-sheet) and the size of these temp files can grow to to a very large size, e.g. for a 20 MB csv data the size of the temp xml file become few GB large. If the "compress" flag is set to true then the temporary XML is gzipped.

Please note the the "compress" option may cause performance penalty.

Setting this option only affects compression for subsequent createSheet() calls.

Parameters:: compress - whether to compress temp files
