1.21.0

  • Added support for custom node locators in the Ketama continuum

1.20.0

  • Added TLS support

1.17.0

1.16.1

  • Add non-authenticated errors for all ASCII operations

1.16.0

  • Add support for ASCII authentication

1.15.0

  • Expose opcode and withCas in SetRequest
  • Expose withCas in binary DeleteRequest

1.14.0

  • core: The Ascii client will behave more similar to Binary client for the case of server returning out-of-memory or value-too-large.

1.13.1

  • folsom-semantic-metrics: Bug-fix for the memcache-hit-ratio gauge

1.13.0

  • Ergonomic feature: Add support for generics when using Serializable transcoder

1.12.1

  • Re-add public methods that were accidentally removed

1.12.0

  • Expose numPendingRequests in RawMemcacheClient

1.11.0

  • Move duplicate method to the Request interface

1.10.0

  • Add support for flags
  • Add micrometer metrics

1.9.2

  • Minor maven related changes

1.9.1

  • Minor maven related changes

1.9.0

  • Add new utility methods for multigets to return maps instead of lists:
    • BinaryMemcacheClient.getAndTouchAsMap
    • MemcacheClient.getAsMap
    • MemcacheClient.casGetAsMap
  • Bump guava from 28.0-android to 29.0-android

1.8.0

  • Add new method getAllNodes() to support advanced custom use cases for multi-node setups.

1.7.4

  • Minor bugfix: metrics for outstanding requests could sometimes return the wrong value after connection is closed

1.7.3

  • Deprecate withRequestTimeoutMillis, replace with withConnectionTimeoutMillis.

1.7.2

  • Add deleteWithCas
  • Take ElastiCache configuration version into account

1.7.1

  • Add elasticache resolver
  • Add BOM artifact

1.6.2

  • Bump dependency versions. This includes major version bumps of com.google.guava:guava and com.spotify.metrics:semantic-metrics-core. Folsom continues supporting also the old versions, so users can delay upgrading if needed.

1.6.1

  • Add support for OpenCensus based tracing

1.6.0

  • Implemented support for reading memcached statistics

1.5.0

  • Added support for setting multiple usernames/passwords for SASL authentications

  • Fixed problem with release being built using a too new JDK, causing runtime errors

1.4.1

  • Fixed bug with reconnections during high request loads

1.4.0

  • Added MemcachedClient.deleteAll() method
  • Reuse existing connections on DNS updates.

1.3.1

  • Fixed bug with the outstanding-requests metric.

1.3.0

  • Extracted Yammer metrics to a separate module to limit dependencies. add "folsom-yammer-metrics" module to your project's dependencies if you need YammerMetrics class.
  • Added support for configurable batch size when creating clients. See the new withRequestBatchSize(int) method in MemcacheClientBuilder.
  • More precise timeout detection (check every 10 ms instead of every second)
  • Always send expiration values to server as TTL instead of timestamp for TTL's up to 30 days.

1.2.1

  • Fixed memory/fd/thread leak introduced in 1.1.0

1.2.0

  • Added MemcachedClient.flushAll() method
  • Add support for SASL authentication for binary protocol

1.1.1

  • Fixed bug with setting too large values

1.1.0
