9019e91 Andrew Kryczka 03 November 2017, 05:16:23 UTC dynamically change current memtable size Summary: Previously setting `write_buffer_size` with `SetOptions` would only apply to new memtables. An internal user wanted it to take effect immediately, instead of at an arbitrary future point, to prevent OOM. This PR makes the memtable's size mutable, and makes `SetOptions()` mutate it. There is one case when we preserve the old behavior, which is when memtable prefix bloom filter is enabled and the user is increasing the memtable's capacity. That's because the prefix bloom filter's size is fixed and wouldn't work as well on a larger memtable.

f90ced9 Yi Wu 02 November 2017, 22:50:30 UTC Blob DB: fix snapshot handling Summary: Blob db will keep blob file if data in the file is visible to an active snapshot. Before this patch it checks whether there is an active snapshot has sequence number greater than the earliest sequence in the file. This is problematic since we take snapshot on every read, if it keep having reads, old blob files will not be cleanup. Change to check if there is an active snapshot falls in the range of [earliest_sequence, obsolete_sequence) where obsolete sequence is 1. if data is relocated to another file by garbage collection, it is the latest sequence at the time garbage collection finish 2. otherwise, it is the latest sequence of the file Closes https://github.com/facebook/rocksdb/pull/3087 Differential Revision: D6182519 Pulled By: yiwu-arbug fbshipit-source-id: cdf4c35281f782eb2a9ad6a87b6727bbdff27a45 03 November 2017, 06:40:01 UTC

Default disable auto garbage collection for now since the whole logic is not fully tested and we plan to make major change to it.

f98efcb Sagar Vemuri 02 November 2017, 19:02:42 UTC Blob DB: Evict oldest blob file when close to blob db size limit Summary: Evict oldest blob file and put it in obsolete_files list when close to blob db size limit. The file will be delete when the `DeleteObsoleteFiles` background job runs next time. For now I set `kEvictOldestFileAtSize` constant, which controls when to evict the oldest file, at 90%. It could be tweaked or made into an option if really needed; I didn't want to expose it as an option pre-maturely as there are already too many :) .

c1e99ed Yi Wu 31 October 2017, 23:33:55 UTC Blob DB: cleanup unused options Summary: * cleanup num_concurrent_simple_blobs. We don't do concurrent writes (by taking write_mutex_) so it doesn't make sense to have multiple non TTL files open. We can revisit later when we want to improve writes. * cleanup eviction callback. we don't have plan to use it now. * rename s/open_simple_blob_files_/open_non_ttl_file_/ and s/open_blob_files_/open_ttl_files_/ to avoid confusion.

9e82540 Yi Wu 27 October 2017, 20:14:34 UTC Blob DB: update blob file format Summary: Changing blob file format and some code cleanup around the change. The change with blob log format are: * Remove timestamp field in blob file header, blob file footer and blob records. The field is not being use and often confuse with expiration field. * Blob file header now come with column family id, which always equal to default column family id. It leaves room for future support of column family. * Compression field in blob file header now is a standalone byte (instead of compact encode with flags field) * Blob file footer now come with its own crc. * Key length now being uint64_t instead of uint32_t * Blob CRC now checksum both key and value (instead of value only). * Some reordering of the fields. The list of cleanups: * Better inline comments in blob_log_format.h * rename ttlrange_t and snrange_t to ExpirationRange and SequenceRange respectively. * simplify blob_db::Reader * Move crc checking logic to inside blob_log_format.cc Closes https://github.com/facebook/rocksdb/pull/3081 Differential Revision: D6171304 Pulled By: yiwu-arbug fbshipit-source-id: e4373e0d39264441b7e2fbd0caba93ddd99ea2af 03 November 2017, 06:37:56 UTC
d66bb21 Yi Wu 26 October 2017, 19:19:43 UTC Blob DB: Inline small values in base DB Summary: Adding the `min_blob_size` option to allow storing small values in base db (in LSM tree) together with the key. The goal is to improve performance for small values, while taking advantage of blob db's low write amplification for large values. Also adding expiration timestamp to blob index. It will be useful to evict stale blob indexes in base db by adding a compaction filter. I'll work on the compaction filter in future patches. See blob_index.h for the new blob index format. There are 4 cases when writing a new key: * small value w/o TTL: put in base db as normal value (i.e. ValueType::kTypeValue) * small value w/ TTL: put (type, expiration, value) to base db. * large value w/o TTL: write value to blob log and put (type, file, offset, size, compression) to base db. * large value w/TTL: write value to blob log and put (type, expiration, file, offset, size, compression) to base db.

05d5c57 Sagar Vemuri 25 October 2017, 23:18:15 UTC Return write error on reaching blob dir size limit Summary: I found that we continue accepting writes even when the blob db goes beyond the configured blob directory size limit. Now, we return an error for writes on reaching `blob_dir_size` limit and if `is_fifo` is set to false. (We cannot just drop any file when `is_fifo` is true.) Deleting the oldest file when `is_fifo` is true will be handled in a later PR.

2b8893b Yi Wu 18 October 2017, 00:24:25 UTC Blob DB: Store blob index as kTypeBlobIndex in base db Summary: Blob db insert blob index to base db as kTypeBlobIndex type, to tell apart values written by plain rocksdb or blob db. This is to make it possible to migrate from existing rocksdb to blob db. Also with the patch blob db garbage collection get away from OptimisticTransaction. Instead it use a custom write callback to achieve similar behavior as OptimisticTransaction. This is because we need to pass the is_blob_index flag to DBImpl::Get but OptimisticTransaction don't support it.

419b93c Yi Wu 17 October 2017, 19:11:52 UTC Blob DB: not writing sequence number as blob record footer Summary: Previously each time we write a blob we write blog_record_header + key + value + blob_record_footer to blob log. The footer only contains a sequence and a crc for the sequence number. The sequence number was used in garbage collection to verify the value is recent. After #2703 we moved to use optimistic transaction and no longer use sequence number from the footer. Remove the footer altogether. There's another usage of sequence number and we are keeping it: Each blob log file keep track of sequence number range of keys in it, and use it to check if it is reference by a snapshot, before being deleted.

The purpose is to 1. Make it possible to open existing rocksdb instance as blob db. Existing value will be of kTypeIndex type, while value inserted by blob db will be of kTypeBlobIndex. 2. Make rocksdb able to detect if the db contains value written by blob db, if so return error. 3. Make it possible to have blob db optionally store value in SST file (with kTypeValue type) or as a blob value (with kTypeBlobIndex type). The root db (DBImpl) basically pretended kTypeBlobIndex are normal value on write. On Get if is_blob is provided, return whether the value read is of kTypeBlobIndex type, or return Status::NotSupported() status if is_blob is not provided. On scan allow_blob flag is pass and if the flag is true, return wether the value is of kTypeBlobIndex type via iter->IsBlob(). Changes on blob db side will be in a separate patch.

1c8dbe2 Andrew Kryczka 17 August 2017, 01:41:18 UTC update scores after picking universal compaction Summary: We forgot to recompute compaction scores after picking a universal compaction like we do in level compaction (https://github.com/facebook/rocksdb/blob/a34b2e388ee51173e44f6aa290f1301c33af9e67/db/compaction_picker.cc#L691-L695). This leads to a fairness issue where we waste compactions on CFs/DB instances that don't need it while others can starve. Previously, ccecf3f4fb8e6eeaa06504b9d477b6db4137831a fixed the issue for the read-amp-based compaction case; this PR avoids the issue earlier and also for size-ratio-based compactions.

eb64253 Maysam Yabandeh 16 August 2017, 23:49:11 UTC Update WritePrepared with the pseudo code Summary: Implement the main body of WritePrepared pseudo code. This includes PrepareInternal and CommitInternal, as well as AddCommitted which updates the commit map. It also provides a IsInSnapshot method that could be later called form the read path to decide if a version is in the read snapshot or it should other be skipped. This patch lacks unit tests and does not attempt to offer an efficient implementation. The idea is that to have the API specified so that we can work on related tasks in parallel.

132306f Sagar Vemuri 15 August 2017, 21:54:41 UTC Remove PartialMerge implementation from Cassandra merge operator Summary: `PartialMergeMulti` implementation is enough for Cassandra, and `PartialMerge` is not required. Implementing both will just duplicate the code. As per https://github.com/facebook/rocksdb/blob/master/include/rocksdb/merge_operator.h#L130-L135 : ``` // The default implementation of PartialMergeMulti will use this function // as a helper, for backward compatibility. Any successor class of // MergeOperator should either implement PartialMerge or PartialMergeMulti, // although implementing PartialMergeMulti is suggested as it is in general // more effective to merge multiple operands at a time instead of two // operands at a time. ``` Closes https://github.com/facebook/rocksdb/pull/2737 Reviewed By: scv119 Differential Revision: D5633073 Pulled By: sagar0 fbshipit-source-id: ef4fa102c22fec6a0175ed12f5c44c15afe3c8ca 15 August 2017, 21:59:34 UTC

We already have logic to add `-std=c++11` to `CXXFLAGS` when the compiler is not MSVC; simply reorder CMakeLists.txt so that logic happens before the calls to `CHECK_CXX_SOURCE_COMPILES`. Additionally add a missing `set(CMAKE_REQUIRED_FLAGS, ...)` before a call to `CHECK_C_SOURCE_COMPILES`.
