Revert "TEPHRA-263 Enforce TTL, regardless of any in-progress transactions. Also Handle the case where TTL is longer than the duration from beginning of epoch to now." This reverts commit a346efe7560cc3b96349263669c4e15951ad401b. This closes #66 Signed-off-by: poorna <poorna@apache.org>
Apache Tephra provides globally consistent transactions on top of distributed data stores such as Apache HBase. While HBase provides strong consistency with row- or region-level ACID operations, it sacrifices cross-region and cross-table consistency in favor of scalability. This trade-off requires application developers to handle the complexity of ensuring consistency when their modifications span region boundaries. By providing support for global transactions that span regions, tables, or multiple RPCs, Tephra simplifies application development on top of HBase, without a significant impact on performance or scalability for many workloads.
Tephra is used by the Apache Phoenix as well to add cross-row and cross-table transaction support with full ACID semantics.
Please refer to the Getting Started guide to start using Apache Tephra.
You can build Tephra directly from the latest source code:
git clone https://git-wip-us.apache.org/repos/asf/incubator-tephra.git cd incubator-tephra mvn clean package
