Subject [jira] [Commented] (PHOENIX-5156) Consistent Global Indexes for Non-Transactional Tables

Kadir OZDEMIR commented on PHOENIX-5156:
----------------------------------------

[~giacomotaylor], [~elserj], [~lhofhansl], [~vincentpoon], [~gjacoby], please see the design
doc at [https://docs.google.com/document/d/1Vsf23GCT0_CK4q8g_xaXyE_4Dw3aH71BfZypEy3T9iQ/edit?usp=sharing|https://docs.google.com/document/d/1Vsf23GCT0_CK4q8g_xaXyE_4Dw3aH71BfZypEy3T9iQ/edit?usp=sharing)]. I
have discussed the solution described in the design doc with [~twdsilva@gmail.com] who has
suggested to create this JIRA. I have updated the design details section based on his feedback.

[~lhofhansl] and [~vincentpoon], I have discussed with you two proposals before on the same
issue and greatly benefitted from these discussions. The solution in this doc is a hybrid
of these proposals.  It turned out that this solution can be implemented quickly as far as
I can see.

If I do not have a hole in the design, this will greatly improve the correctness of global
indexes. It is a very short document and should not take much of your time. I am looking forward
to your feedback.

> Without transactional tables, the global indexes can get easily out of sync with their
data tables in Phoenix. Transactional tables require a separate transaction manager, have
some restrictions and performance penalties. This issue is to have consistent global indexes
without the need for using transactional tables.
