Connect2id server 14.10

2023-11-22

This Connect2id server release improves the performance of expired entry purges in deployments with an SQL database. If you have an identity provider deployment that deals with a large number of sessions and identifier-based access tokens, objects that eventually expire, this upgrade will reduce the database traffic and load when the purge task runs.

The SQL connector also adds two Java system properties:

  • dataSource.maxLifetime -- Overrides the maximum SQL connection lifetime (in the Hikari connection pool)

  • dataSource.expiredQueryPageLimit -- Overrides the page limit in SQL select statements for expired records.

These two new properties are explained in the configuration docs for the supported SQL databases:

The dataSource.maxLifetime configuration override can be useful to address situations where the backend SQL database is configured to close connections before their expiration in the Connect2id server pool (30 minutes).

The release notes below have more information.

Release notes

14.10 (2023-11-22)

Summary

  • Connect2id server deployments with an SQL database receive an optimised purge task and SQL query for expired records, such as records for expired subject sessions or identifier-based access tokens. The page limit in the SQL query to select expired records is made configurable, to enable further performance tuning.

    A Java system property to override the maximum lifetime of SQL connections in the connection pool is also made available.

Configuration

  • /WEB-INF/infinispan-*-{mysql|oracle|postgres95|sqlserver}.xml

    • Upgrades the SQL store schema to v3.2.

    • dataSource.maxLifetime -- New optional Java system property to override the default maximum lifetime of SQL connections in the Hikari connection pool. The value is expressed in microseconds and must not be shorter than 30000 (30 seconds). The default value is 1800000 (30 minutes).

      This configuration can be used to address Hikari warnings (recorded in the Connect2id server log) "Failed to validate connection (Closed Connection)".

    • dataSource.expiredQueryPageLimit -- New optional Java system property to override the default page limit of SQL queries to select expired records, such as the records of expired subject sessions. The page limit value is 1000 records.

      This configuration can be used to optimise the retrieval of expired records by the Infinispan entry purge task.

    • Upgrades the SQL database connector and the sessionStore.sessionMap, authzStore.idAccessTokenMap, authzStore.expendedTokenMap, op.authSessionMap, clients.registrationsMap SQL definitions to select only expired records from the respective tables when the Infinispan purge task runs.

Resolved issues

  • The expired entry reaper in Connect2id server deployments with an SQL database must not terminate when an unchecked exception is encountered during an SQL select or delete query. The exception must be swallowed and an appropriate error logged (issue sql-store/31, sql-store/32).

  • The infinispan-replication-*.xml configurations must not use passivation for sessionStore.sessionMap and sessionStore.subjectMap as this is incompatible with shared cache stores (issue server/943).

  • Reduces and aligns the memory max-count limits in the infinispan-*-local-h2.xml configurations (issue server/944).

  • The page LIMIT in the SQL select query run by the purge task must be inlined (issue sql-store/29).

Dependency changes

  • Updates to com.nimbusds:oauth2-authz-store:24.8

  • Updates to com.nimbusds:oidc-session-store:16.8

  • Updates to com.nimbusds:infinispan-cachestore-sql:7.4.1

  • Updates to com.zaxxer:HikariCP:5.1.0

  • Updates to Log4j 2.22.0

Connect2id server 14.9

2023-11-13

This release ships an enhancement for Connect2id server deployments with an AWS DynamoDB. The purge thread that wakes up periodically to scan the subject (end-user) sessions table for expired entries and then delete them, will now automatically limit the rate of read and write capacity unit consumption to 10% of the provisioned for the sub_sessions table.

The rate limiting moderates the use of capacity units when the purge thread is running. With a DynamoDB table in provisioned mode the rate limiting ensures the scan (and delete) requests will not potentially starve regular API requests of database capacity. In on-demand mode the rate limiting smooths potential peaks in capacity use and thus can help reduce your AWS bill.

The default configuration can be overridden with a dynamodb.purgeMaxReadCapacity Java system property, by setting it to an absolute capacity unit value, or to a percentage (evaluated using the reported provisioned read capacity every time before the purge thread runs).

Example override to use at most 20 read capacity units / second for purges:

dynamodb.purgeMaxReadCapacity=20

Example override to rate limit the consumption to 15% of the current read capacity units for the table:

dynamodb.purgeMaxReadCapacity=15%

Note that when automatic DynamoDB TTL expiration is enabled for the sessions table the Connect2id server will not run the purge thread (as all sessions are being expired within DynamoDB) and the dynamodb.purgeMaxReadCapacity will have no effect then.

Release notes

14.9 (2023-11-13)

Summary

  • Connect2id server deployments with an AWS DynamoDB receive rate limiting of the paged scan and delete requests that purge the database of expired subject sessions. This enhancement guards regular requests to DynamoDB from potentially being starved of their provisioned database read and write capacity when a purge scan is taking place. Moderating the purge scans may also smooth spikes in DynamoDB consumption over time and thus enable the provisioned capacity to be lowered to save costs.

    Note, in deployments where native DynamoDB TTL expiration is enabled for the subject sessions, by setting the "dynamodb.enableTTL.sessionStore.sessionMap" Java system property to true, the sessions will be expired automatically by DynamoDB and the Connect2id server doesn't need to run purge scans on the sessions table. The TTL expiration suits Connect2id server deployments that have no OpenID relying parties registered to receive logout and session expiration notifications. Such notifications can be generated only when the sessions are expired by the Connect2id server itself.

Configuration

  • /WEB-INF/infinispan-*-dynamodb.xml

    • Upgrades the dynamodb schema to v2.1.

  • /WEB-INF/infinispan-*-{stateless|replication}-dynamodb.xml

    • Scan and delete requests that purge the sub_sessions table of expired subject sessions are rate limited to 10% of the reported provisioned read capacity for the table. For example, if the table is provisioned with 100 read capacity units, the consumed purge scan read and delete operations will be rate-limited to 10 capacity units.

      To specify a different value set the "dynamodb.purgeMaxReadCapacity" Java system property to the desired maximum read capacity units that may be consumed during a purge, as an absolute value, e.g. 20, or as a percentage of the current provisioned read capacity of the table, e.g. 20%. Any write capacity consumed to delete expired items is bounded by the "dynamodb.purgeMaxReadCapacity" and will always stay below it. The default value of "dynamodb.purgeMaxReadCapacity" is 10%, as explained above.

Resolved issues

  • The expired entry reaper in Connect2id server deployments with an AWS Dynamo database must not terminate when an unchecked parse or another exception is thrown when parsing a retrieved DynamoDB item. This may occur in DynamoDB items manipulated outside the Connect2id server APIs. Instead, the exception must be swallowed and an error with the offending item logged. This is now done with a DS0152 log error (issue dynamodb-store/21).

  • The *.dynamoDB.deleteTimer metrics must include DynamoDB delete requests performed as part of purges of expired items (issue dynamodb-store/22).

  • Removes legacy comma separator support in Scope.parse(String) (issue oidc-sdk/445).

  • Updates to com.nimbusds:nimbus-jose-jwt:9.37.1

Resolved issues

  • Fixes a bug introduced in v14.8.1 that affects Connect2id server deployments with an SQL database. The bug resulted in repeat duplicate SQL delete queries when purging expired records in the database, causing excessive slowdown of the purge task in SQL tables with many expired records, such as records for subject sessions (issue server/938, sql-store/25).

  • The *.sqlStore.deleteTimer metrics must include SQL delete queries performed as part of purges of expired records (issue sql-store/26).

Dependency changes

  • Updates to com.nimbusds:oauth2-authz-store:24.7.2

  • Updates to com.nimbusds:oidc-session-store:16.7.4

  • Updates to com.nimbusds:infinispan-cachestore-sql:7.1.1

Connect2id server 14.8.2

2023-11-02

This second Connect2id server release for today fixes an issue in v14.8.1 with the Log4j Web 2.21.1 BOM that introduced an erroneous transitive dependency to two Spring artifacts. The erroneous dependency is now removed and we'll make a report upstream.

As always, more information can be found in the release notes below.

Connect2id server 14.8.1

2023-11-02

This maintenance release of the Connect2id server addresses issues related to the SQL database connector, which is now optimised to conserve memory when purging expired entres. An issue slowing down the server startup with Oracle Databases is also fixed. If you have a deployment that uses an SQL database and deals with significant traffic updating to 14.8.1 is recommended.

Updating to 14.8.1 can be skipped if you have a Connect2id server deployment that uses DynamoDB.

Release notes

14.8.1 (2023-11-02)

Resolved issues

  • Updates the expired entry reaper for Connect2id server deployments with an SQL database to conserve memory by employing paged key set seek, in sets of up to 100 SQL records and interleaving the record deletion between the pages. Intended to prevent OOM errors in deployments with a very large number of sessions and other expiring objects (issue server/935).

  • Optimises the dataSource.createTableIfMissing implementation for Oracle Databases when the queried table has a very large number of records, causing Connect2id server startup to pause for times longer than 1 minute at startup. The issue is addressed by switching from LIMIT 0 to LIMIT 1 in the query to obtain the table's column names (issue server/933).

  • The expired entry reaper in Connect2id server deployments with an SQL database must not terminate when an unchecked parse or another exception is thrown when parsing a retrieved SQL record. This may occur in SQL records manipulated outside the Connect2id server APIs. Instead, the exception must be swallowed and an error with the offending SQL record logged. This is now done with an IS0141 log error (issue sql-store/23).

  • Fixes the default value and parsing of the optional sessions form parameter of the /session-store/rest/v2/purge resource (issue session-store/95).

Dependency changes

  • Updates to com.nimbusds:oauth2-authz-store:24.7.1

  • Updates to com.nimbusds:oidc-session-store:16.7.3

  • Upgrades to com.nimbusds:infinispan-cachestore-sql:7.1

  • Updates to Log4j 2.21.1

  • Updates to Dropwizard Metrics 4.2.20.
