Patrick Xiaoman Huang updated TEPHRA-246:
-----------------------------------------
    Comment: was deleted

(was: Maybe we can try TCompactProtocol first.
Default TBinaryProtocol write long with 8byte, and TCompactProtocol transform i64 to zigzag
int, then write with 10byte var int.)

> The current codec simply uses Thrift. However, with large invalid lists, the encoded
byte array cvan become very large, Using compression techniques such as delta encoding, variable
length integer encoding, or simple compression can greatly reduce the size of the encoded
byte array, as well as the time it takes to encode, transmit, and decode the transaction.

> This can be applied to the transactions in the Thrift protocol as well as to the transactions
that are attached to the HBase operations.
