Providing Durability of In-Memory Columnar Datastores Using Multile Logs
First Claim
1. A computer-implemented method in a database system, comprising:
- receiving, from a client, a request to perform a transaction, the transaction requiring two or more database tables in an in-memory column-oriented data store;
performing the transaction on each of the two or more database tables, wherein performance of the transaction generates two or more commit fragments corresponding to each of the two or more database tables; and
updating a transaction log and a commit log according to the generated two or more commit fragments.

Abstract
Embodiments described herein generally relate to providing durability of in memory columnar datastores using multiple logs. A computer-implemented method is described. The method includes receiving a request to perform a transaction involving multiple tables in a column-oriented database system. The method further includes performing the transaction on each of the two or more database tables. Performance of the transaction generates two or more commit fragments corresponding to each of the two or more database tables. The method further includes writing each commit fragment to a transaction log for each of the two or more database tables. The method also includes writing a commit record for the transaction to a commit log after all commit fragments have been written.

8. A system, comprising:
-
one or more processors; and a memory, the memory storing instructions that, when executed by the one or more processors, cause the one or more processors to; receive, from a client, a request to perform a transaction, the transaction requiring two or more database tables in an in-memory column-oriented data store; perform the transaction on each of the two or more database tables, wherein performance of the transaction generates two or more commit fragments corresponding to each of the two or more database tables; and update a transaction log and a commit log according to the generated two or more commit fragments. - View Dependent Claims (9, 10, 11, 12, 13, 14)

-
receiving, from a client, a request to perform a transaction, the transaction requiring two or more database tables in an in-memory column-oriented data store; performing the transaction on each of the two or more database tables, wherein performance of the transaction generates two or more commit fragments corresponding to each of the two or more database tables; and updating a transaction log and a commit log according to the generated two or more commit fragments. - View Dependent Claims (16, 17, 18, 19, 20)
