java.lang.Object

org.apache.jackrabbit.oak.plugins.document.rdb.RDBDocumentStore

All Implemented Interfaces:

DocumentStore

public class RDBDocumentStore
extends java.lang.Object
implements DocumentStore

Implementation of DocumentStore for relational databases.

Supported Databases

The code is supposed to be sufficiently generic to run with a variety of database implementations. However, the tables are created when required to simplify testing, and that code specifically supports these databases:

• H2DB
• Apache Derby
• IBM DB2
• PostgreSQL
• MariaDB (MySQL)
• Microsoft SQL Server
• Oracle

Table Layout

Data for each of the DocumentStore's Collections is stored in its own database table (with a name matching the collection).

The tables essentially implement key/value storage, where the key usually is derived from an Oak path, and the value is a serialization of a Document (or a part of one). Additional fields are used for queries, debugging, and concurrency control:

Column	Type	Description
ID	varchar(512) not null primary key	The document's key (for databases that can not handle 512 character primary keys, such as MySQL, varbinary is possible as well).
MODIFIED	bigint	Low-resolution timestamp.
HASBINARY	smallint	Flag indicating whether the document has binary properties.
DELETEDONCE	smallint	Flag indicating whether the document has been deleted once.
MODCOUNT	bigint	Modification counter, used for avoiding overlapping updates.
DSIZE	bigint	The approximate size of the document's JSON serialization (for debugging purposes).
VERSION	smallint	The schema version the code writing to a row (or inserting it) was aware of (introduced with schema version 1). Not set for rows written by version 0 client code.
SDTYPE	smallint	Split Document type.
SDMAXREVTIME	bigint	Split document max revision time..
DATA	varchar(16384)	The document's JSON serialization (only used for small document sizes, in which case BDATA (below) is not set), or a sequence of JSON serialized update operations to be applied against the last full serialization.
BDATA	blob	The document's JSON serialization (usually GZIPped, only used for "large" documents).

The names of database tables can be prefixed; the purpose is mainly for testing, as tables can also be dropped automatically when the store is disposed (this only happens for those tables that have been created on demand).

Versioning

The initial database layout used in OAK 1.0 through 1.6 is version 0.

Version 1 introduces an additional "version" column, which records the schema version of the code writing to the database (upon insert and update). This is in preparation of future layout changes which might introduce new columns.

Version 2 introduces an additional "sdtype" and "sdmaxrevtime".

The code deals with both version 0, version 1 and version 2 table layouts. By default, it tries to create version 2 tables, and also tries to upgrade existing version 0 and 1 tables to version 2.

DB-specific information

Databases need to be configured so that:

• Text fields support all Unicode code points,
• Collation of text fields happens by Unicode code point,
• and BLOBs need to support at least 16 MB.

See the RDBDocumentStore documentation for more information.

Table Creation

The code tries to create the tables when they are not present. Likewise, it tries to upgrade to a newer schema when needed.

Users/Administrators who prefer to stay in control over table generation can create them "manually". The oak-run "rdbddldump" command can be used to print out the DDL statements that would have been used for auto-creation and/or automatic schema updates.

Caching

The cache borrows heavily from the MongoDocumentStore implementation.

Queries

The implementation currently supports only three indexed properties: "_bin", "deletedOnce", and "_modified". Attempts to use a different indexed property will cause a DocumentStoreException.

                                   java.lang.String id)

Description copied from interface: DocumentStore

Get the document with the given key. This is a convenience method and equivalent to DocumentStore.find(Collection, String, int) with a maxCacheAge of Integer.MAX_VALUE.

The returned document is immutable.

Specified by:

find in interface DocumentStore

Type Parameters:

T - the document type

Parameters:

remove

public <T extends Document> void remove(Collection<T> collection,
                                        java.lang.String id)

Description copied from interface: DocumentStore

Remove a document. This method does nothing if there is no document with the given key.

In case of a DocumentStoreException, the document with the given key may or may not have been removed from the store. It is the responsibility of the caller to check whether it still exists. The implementation however ensures that the result of the operation is properly reflected in the document cache. That is, an implementation could simply evict the document with the given key.

Specified by:

remove in interface DocumentStore

Type Parameters:

T - the document type

Parameters:

collection - the collection

id - the key

remove

public <T extends Document> void remove(Collection<T> collection,
                                        java.util.List<java.lang.String> ids)

Description copied from interface: DocumentStore

Batch remove documents with given keys. Keys for documents that do not exist are simply ignored. If this method fails with an exception, then only some of the documents identified by keys may have been removed.

In case of a DocumentStoreException, the documents with the given keys may or may not have been removed from the store. It may also be possible that only some have been removed from the store. It is the responsibility of the caller to check which documents still exist. The implementation however ensures that the result of the operation is properly reflected in the document cache. That is, an implementation could simply evict documents with the given keys from the cache.

Specified by:

remove in interface DocumentStore

Type Parameters:

T - the document type

Parameters:

collection - the collection

ids - list of keys

remove

public <T extends Document> int remove(Collection<T> collection,
                                       java.util.Map<java.lang.String,java.lang.Long> toRemove)

Description copied from interface: DocumentStore

Batch remove documents with given keys and corresponding equal conditions on NodeDocument.MODIFIED_IN_SECS values. Keys for documents that do not exist are simply ignored. A document is only removed if the corresponding condition is met.

In case of a DocumentStoreException, the documents with the given keys may or may not have been removed from the store. It may also be possible that only some have been removed from the store. It is the responsibility of the caller to check which documents still exist. The implementation however ensures that the result of the operation is properly reflected in the document cache. That is, an implementation could simply evict documents with the given keys from the cache.

Specified by:

remove in interface DocumentStore

Type Parameters:

T - the document type

Parameters:

collection - the collection.

toRemove - the keys of the documents to remove with the corresponding timestamps.

Returns:

the number of removed documents.

remove

public <T extends Document> int remove(Collection<T> collection,
                                       java.lang.String indexedProperty,
                                       long startValue,
                                       long endValue)
                                throws DocumentStoreException

Description copied from interface: DocumentStore

Batch remove documents where the given "indexed property" is within the given range (exclusive) - (startValue, endValue).

The indexed property is a Long value and numeric comparison applies.

In case of a DocumentStoreException, the documents with the given keys may or may not have been removed from the store. It may also be possible that only some have been removed from the store. It is the responsibility of the caller to check which documents still exist. The implementation however ensures that the result of the operation is properly reflected in the document cache. That is, an implementation could simply evict documents with the given keys from the cache.

Specified by:

remove in interface DocumentStore

Type Parameters:

T - the document type

Parameters:

collection - the collection.

indexedProperty - the name of the indexed property

startValue - the minimum value of the indexed property (exclusive)

endValue - the maximum value of the indexed property (exclusive)

Returns:

the number of removed documents.

Throws:

DocumentStoreException - if the operation failed. E.g. because of an I/O error.

create

public <T extends Document> boolean create(Collection<T> collection,
                                           java.util.List<UpdateOp> updateOps)

Description copied from interface: DocumentStore

Try to create a list of documents. This method returns true iff none of the documents existed before and the create was successful. This method will return false if one of the documents already exists in the store. Some documents may still have been created in the store. An implementation does not have to guarantee an atomic create of all the documents described in the updateOps. It is the responsibility of the caller to check, which documents were created and take appropriate action. The same is true when this method throws DocumentStoreException (e.g. when a communication error occurs). In this case only some documents may have been created.

Specified by:

create in interface DocumentStore

Type Parameters:

T - the document type

Parameters:

collection - the collection

updateOps - the list of documents to add (where UpdateOp.Conditions are not allowed)

Returns:

true if this worked (if none of the documents already existed)

createOrUpdate

public <T extends Document> T createOrUpdate(Collection<T> collection,
                                             UpdateOp update)

Description copied from interface: DocumentStore

Atomically checks if the document exists and updates it, otherwise the document is created (aka "upsert"), unless the update operation requires the document to be present (see UpdateOp.isNew()). The returned document is immutable.

If this method fails with a DocumentStoreException, then the document may or may not have been created or updated. It is the responsibility of the caller to check the result e.g. by calling DocumentStore.find(Collection, String). The implementation however ensures that the result of the operation is properly reflected in the document cache. That is, an implementation could simply evict documents with the given keys from the cache.

Specified by:

createOrUpdate in interface DocumentStore

Type Parameters:

T - the document type

Parameters:

collection - the collection

update - the update operation (where UpdateOp.Conditions are not allowed)

Returns:

the old document or null if it either didn't exist before, or the UpdateOp required the document to be present but UpdateOp.isNew() was false.

createOrUpdate

public <T extends Document> java.util.List<T> createOrUpdate(Collection<T> collection,
                                                             java.util.List<UpdateOp> updateOps)

Description copied from interface: DocumentStore

Create or unconditionally update a number of documents. An implementation does not have to guarantee that all changes are applied atomically, together.

In case of a DocumentStoreException (e.g. when a communication error occurs) only some changes may have been applied. In this case it is the responsibility of the caller to check which UpdateOps were applied and take appropriate action. The implementation however ensures that the result of the operations are properly reflected in the document cache. That is, an implementation could simply evict documents related to the given update operations from the cache.

Specified by:

createOrUpdate in interface DocumentStore

Type Parameters:

T - the document type

Parameters:

collection - the collection

updateOps - the update operation list

Returns:

the list containing old documents or null values if they didn't exist before (see DocumentStore.createOrUpdate(Collection, UpdateOp)), where the order reflects the order in the "updateOps" parameter

findAndUpdate

public <T extends Document> T findAndUpdate(Collection<T> collection,
                                            UpdateOp update)

Description copied from interface: DocumentStore

Performs a conditional update (e.g. using UpdateOp.Condition.Type.EXISTS and only updates the document if the condition is true. The returned document is immutable.

In case of a DocumentStoreException (e.g. when a communication error occurs) the update may or may not have been applied. In this case it is the responsibility of the caller to check whether the update was applied and take appropriate action. The implementation however ensures that the result of the operation is properly reflected in the document cache. That is, an implementation could simply evict the document related to the given update operation from the cache.

Specified by:

findAndUpdate in interface DocumentStore

Type Parameters:

T - the document type

Parameters:

collection - the collection

update - the update operation with the condition

Returns:

the old document or null if the condition is not met or if the document wasn't found

invalidateCache

public CacheInvalidationStats invalidateCache()

Description copied from interface: DocumentStore

Invalidate the document cache. Calling this method instructs the implementation to invalidate each document from the cache, which is not up to date with the underlying storage at the time this method is called. A document is considered in the cache if DocumentStore.getIfCached(Collection, String) returns a non-null value for a key.

An implementation is allowed to perform lazy invalidation and only check whether a document is up-to-date when it is accessed after this method is called. However, this also includes a call to DocumentStore.getIfCached(Collection, String), which must only return the document if it was up-to-date at the time this method was called. Similarly, a call to DocumentStore.find(Collection, String) must guarantee the returned document reflects all the changes done up to when invalidateCache() was called.

In some implementations this method can be a NOP because documents can only be modified through a single instance of a DocumentStore.

Specified by:

invalidateCache in interface DocumentStore

Returns:

cache invalidation statistics or null if none are available.

invalidateCache

public CacheInvalidationStats invalidateCache(java.lang.Iterable<java.lang.String> keys)

Description copied from interface: DocumentStore

Invalidate the document cache but only with entries that match one of the keys provided. See DocumentStore.invalidateCache() for the general contract of cache invalidation.

Specified by:

invalidateCache in interface DocumentStore

Parameters:

keys - the keys of the documents to invalidate.

Returns:

cache invalidation statistics or null if none are available.

invalidateCache

public <T extends Document> void invalidateCache(Collection<T> collection,
                                                 java.lang.String id)

Description copied from interface: DocumentStore

Invalidate the document cache for the given key. See DocumentStore.invalidateCache() for the general contract of cache invalidation.

Specified by:

invalidateCache in interface DocumentStore

Parameters:

collection - the collection

id - the key

determineServerTimeDifferenceMillis

public long determineServerTimeDifferenceMillis()

Specified by:

determineServerTimeDifferenceMillis in interface DocumentStore

Returns:

the estimated time difference in milliseconds between the local instance and the (typically common, shared) document server system. The value can be zero if the times are estimated to be equal, positive when the local instance is ahead of the remote server and negative when the local instance is behind the remote server. An invocation is not cached and typically requires a round-trip to the server (but that is not a requirement).

getDroppedTables

public java.lang.String getDroppedTables()

getTableNames

public static java.util.List<java.lang.String> getTableNames()

dispose

public void dispose()

Description copied from interface: DocumentStore

Dispose this instance.

Specified by:

dispose in interface DocumentStore

getIfCached

public <T extends Document> T getIfCached(Collection<T> collection,
                                          java.lang.String id)

Description copied from interface: DocumentStore

Fetches the cached document. If the document is not present in the cache null will be returned. This method is consistent with other find methods that may return cached documents and will return null even when the implementation has a negative cache for documents that do not exist. This method will never return NodeDocument.NULL.

Specified by:

getIfCached in interface DocumentStore

Type Parameters:

T - the document type

Parameters:

collection - the collection

id - the key

Returns:

cached document if present. Otherwise null.

getCacheStats

public java.lang.Iterable<CacheStats> getCacheStats()

Specified by:

getCacheStats in interface DocumentStore

Returns:

status information about the cache

getMetadata

public java.util.Map<java.lang.String,java.lang.String> getMetadata()

Specified by:

getMetadata in interface DocumentStore

Returns:

description of the underlying storage.

getStats

@NotNull
public @NotNull java.util.Map<java.lang.String,java.lang.String> getStats()

Statistics are generated for each table. The following fields are always added:

tableName.ns

fully qualified name of the database table

tableName.schemaInfo

DDL information for table, as obtained during startup

tableName.indexInfo

DDL information for associated indexes, as obtained during startup

tableName.count

exact number of rows

In addition, some statistics information for Collection.CLUSTER_NODES is added:

clusterNodes.updates

Writes to the table, counted by cluster node ID

Finally, additional database-specific statistics may be added; see descriptions in RDBDocumentStoreDB.getAdditionalStatistics(RDBConnectionHandler, String, String) for details.

Specified by:

getStats in interface DocumentStore

Returns:

statistics about this document store.
